Proviamo a trarre alcune conclusioni, tra le molte possibili, da quanto abbiamo fino ad ora esposto. Conclusioni le quali, contenendo inevitabilmente il senso di una proposta critica, superano, in qualche modo, i limiti del corso, e che tuttavia sono utili, ci sembra, a completare la sistemazione stessa della materia come “organismo” teorico e didattico, a rendere esplicito come le diverse parti non siano solo legate da un rapporto di necessità, ma da un “orientamento”.

Nella costante trasformazione degli organismi edilizi attraverso le infinite revisioni e rinnovi del tipo, l’essenza dell’atto costruttivo, abbiamo visto, rimane costante nel tempo: essa consiste nel gesto fondativo di prendere possesso, orientare e proteggere uno spazio. Eppure questo non basta. Occorre all’uomo, animale politico, che il senso della fondazione sia reso leggibile, diventi gesto comunicabile: ripetuto e convenzionale, quindi simbolico. La geometrizzazione dei gesti di fondazione, ereditati nel corso del tempo dal mondo preriflessivo, annuncia il nuovo edificio stabilendo la posizione del nodo dove il costruttore annoderà, al colmo del tetto, le travi di copertura, l’asse dove la porta indicherà il verso di percorrenza: assegna un centro, stabilisce direzioni, organizza il recinto in modo leggibile. Collega, anche, il nuovo edificio a tutti gli infiniti edifici che lo hanno preceduto, e dei quali quello che sta per iniziare sarà un aggiornamento, un contributo al patrimonio di esperienze che il tipo ha conquistato nel tempo. Ogni atto costruttivo ha senso se partecipa (se è parte) di un processo operante, riassumendo la propria matrice fondativa attraverso il riconoscimento dei gesti tettonici iniziali: ogni costruzione diviene, in questo senso, originale, individuo edilizio capace di “ripossedere” la propria origine.

Nel mondo primitivo e arcaico questo eterno ritorno avveniva attraverso la sacralizzazione del gesto di fondazione, nel mondo antico e premoderno attraverso la ritualizzazione: forme diverse di codificazione riconducibili, tutte, ad un unico principio iterativo, storicamente diversificato, che governa la costruzione.

Abbiamo cercato di dimostrare come, nel mondo moderno e desacralizzato, il riconoscimento delle matrici trasmesse dal tipo costituisca l’ultimo legame possibile, e per questo preziosissimo, tra quanto andiamo costruendo e le nostre radici sulla terra: esso restituisce i riferimenti, le coordinate spazio-temporali. Fornisce l’orientamento. Il carattere sintetico del pensiero arcaico, che si sforza di trasformare il Caos in Cosmos attraverso la ripetizione del tempo mitico delle origini, l’aspirazione all’unità leggibile negli organismi prodotti dalle prime forme di socializzazione delle società preurbane, l’ordine mirabile della città antica, ma anche il bisogno di principi ordinatori (e non regole), latente nel pensiero moderno, possono venire, per questa via, ereditati dal pensiero sistematico contemporaneo, leggendo negli edifici la loro essenza fenomenica, manifestazione di un’esperienza processualmente individuabile e rapportabile al sistema di valori civili che ha prodotto l’universo costruito, come testimonianze operanti di gesti costruttivi concreti. Una razionale cosmogonia, in altri termini, capace di informare la concezione “totale” dell’organismo, dove l’innovazione costituisce l’incipit vita nova fondato non su cataloghi, inventari, elenchi di idee, ma sui pochi gesti elementari eternamente rinnovati che leggono, della realtà, l’essenziale e lo stabile, distinguendolo dal superfluo e dal transeunte delle mode che devastano la nostra disciplina, ma anche dall’accessorio che spesso l’architetto elegge nella storia a pretesto per la spettacolarizzazione dei propri prodotti.

Ci rendiamo conto della inattualità di una tale proposta, in un momento in cui la cultura è occupata a riflettere sull’impossibilità dei procedimenti onnicomprensivi e trovano largo impiego termini quali “microstoria”, “pensiero debole”, “decostruzione”. Eppure, per il progettista, obbligato alla sintesi dall’urgenza delle scelte, la salvezza dalla storia (intuizione latente nel pensiero moderno che i grandi architetti del passato, tuttavia, inconsciamente possedevano) consiste nel togliere le incrostazioni del particolare, che ne oscurano il senso, dai nessi che individuano nel tempo la struttura processuale profonda e operante dei fenomeni; nel cogliere la capacità di rigenerazione degli organismi edilizi ed urbani a partire dalle matrici fondative. Rigenerazione capace di liberarci, auspicabile corollario, tanto dalle letture spesso estetizzanti dei molti critici che hanno contribuito ad immettere la nostra disciplina nel circuito del puro consumo dell’immagine, quanto dalla storiografia intesa come distesa di rovine, museo polveroso e, in fondo, inutile. Inserire il mondo, sempre più autobiografico e privato, del progetto nel circuito della realtà costruita individuando il senso collettivo delle matrici formative dei tipi e del loro processo di trasformazione: sembra essere questo, nelle condizioni di crisi nelle quali versa oggi la disciplina, l’unico modo di superare accademie e fughe nell’universo mercificato dei media. Senza questo legame ogni innovazione è prodotto rivolto al mercato dell’immagine, si esaurisce all’interno dei circuiti del gusto e delle mode. Proviamo a riflettere, al riguardo, su uno dei caratteri più significativi ed evidenti dell’architettura moderna, dilapidato dalla superficialità di un impiego distratto, privo di ragioni strutturali, come l’attenzione all’asimmetria delle forme. Accennavamo, nell’introduzione a queste note, ad un pensiero sistematico che si svolge per diadi, ereditate dalla coscienza spontanea del costruttore arcaico, delle quali vanno riconosciuti tanto i caratteri di opposizione e complementarità, quanto la potenziale integrabilità a costituire sintesi organiche. Un sistema binario dove ogni carattere acquista senso in quanto esiste il suo contrario. Ma abbiamo anche appreso in seguito come, nel mondo illusoriamente simmetrico della diade, un terzo fattore sposti l’asse del problema: in realtà gli opposti termini sono affetti, oltre che dalle qualità di antagonismo e complementarità, da una terza qualità: la polarità, che introduce l’elemento dinamico distinguendo le capacità, “polarizzanti” appunto, di uno dei due termini, immettendo nell’organismo il germe vitale dell’asimmetria.

Il diverso senso, funzionale-simbolico, dei termini duali è legato all’esperienza concreta che appartiene ad ogni aspetto della realtà: il diverso senso convenzionale della mano destra rispetto alla sinistra, del maschile rispetto al femminile, dell’oscurità rispetto alla luce, lo stesso mondo abitato diviso in due dal corso del sole (ogni civiltà ha un suo nord e un suo sud affetti da diversi caratteri allo stesso tempo antagonisti e complementari) così come nello spazio costruito è diverso il senso tra elementi diadici, ad esempio, del percorso: porta, portale, ingresso, soglia, uscio, adito, varco, da una parte, e braciere, camino, abside, altare, trono, mirhab, immagine del dio o del sovrano dall’altra, essendo implicito, nei termini, il valore di strumento polarizzante del primo rispetto al valore di fine polarizzante del secondo. Coinvolgendo un moto e una direzione, la polarizzazione indica la vita dell’edificio, legando la sua geometria al consumo che dell’edificio verrà fatto. “Consumo” e non “uso”, contenendo il primo termine il concetto di esperienza ripetuta nel tempo, che esaurisce o trasforma l’oggetto utilizzato conservandone la memoria dei caratteri tipici. Ma riguardando anche i caratteri degli organismi architettonici nel loro divenire storico-processuale, la polarizzazione della diade fornisce senso (verso, orientamento) anche a sequenze di mutazioni (abbiamo esemplificato alcune delle più semplici nel passaggio dal recinto alla copertura, dalla serie al nodo, dal frammentario all’organico) ciclicamente ricorrenti. L’organismo edilizio è dunque il risultato di un equilibrio dinamico prodotto da termini polarizzanti che impediscono lo stato di pura quiete attraverso l’asimmetrica gerarchizzazione degli elementi binari. L’edificio costruito coglie, nel tempo e nello spazio, uno di questi provvisori stati di equilibrio, divenendo esso stesso luogo di nuove, possibili forme di stabilità attraverso mutazioni, trasformazioni, reimpieghi. La regolarità che il pensiero sistematico induce negli organismi edilizi non è, dunque, l’asettica perfezione geometrica del cristallo, di simmetrica astrazione: abbiamo visto come, ad esempio, nel processo di trasformazione dei tipi, l’impianto perfettamente centrale costituisca pura ricerca intellettuale slegata dalla realtà fenomenica delle trasformazioni edilizie. Il mondo costruito rispecchia la complessità della vita, dei percorsi, del moto: esso presenta versi e discontinuità nella distribuzione, nell’apparecchio statico-costruttivo, nell’aspetto visibile, nel modo stesso di organizzare (di trasformare in organismo) questi sistemi in sintesi leggibile.

Ebbene, se una delle conquiste della modernità consiste proprio nel riconoscimento di questa sostanziale discontinuità ed asimmetria nell’universo, l’architettura moderna, soprattutto nelle versioni volgarizzate dagli epigoni dei “pionieri”, ha dato a questo riconoscimento, sulla scia delle arti figurative, una traduzione pittoresca e imitativa senza riconoscerne, in sostanza, la struttura di caratteri processualmente costanti: il senso strutturante dell’opposizione, della complementarità, della polarizzazione. L’asimmetria è così divenuta, per questa strada dalle origini complesse eppure semplicissima da riconoscere, carattere distintivo portatore di valori autonomi, assoluti, propiziatori di modernità: vero esorcismo dell’architettura del XX secolo.

Ma noi non avalleremo, in coerenza con le considerazioni fin qui riportate, un’interpretazione dell’architettura moderna come collettiva, catastrofica dissoluzione. Se intendiamo la civiltà, ogni civiltà, e quindi anche quella contemporanea, come manifestazione concreta e prodotto organico di una società, e dunque essa stessa organismo in continua trasformazione, la modernità ci appare come fase critica di uno svolgimento che si rinnova ciclicamente. Il fatto stesso che l’architettura moderna si sia storicizzata contraddicendo i propri stessi manifesti, che abbia riconosciuto al suo interno fasi e processi e ne abbia preso coscienza, è il sintomo evidente di come nulla di quello che l’uomo ha costruito possa essere veramente distrutto. E la constatazione che noi non abbiamo ereditato un pugno di cenere è perfino più importante dell’ambiguità del lascito. Anzi, permette di comporre, superandola, quella stessa ambiguità.

Torniamo alla capanna primitiva.

Ciclicamente la trattatistica ha utilizzato questo tema per i propri fini: dimostrare una chiave di lettura, surrogare una teoria, affermare un principio. L’interpretazione della capanna primitiva corrisponde, in ultima analisi, al desiderio di un solo, unico principio unitario, capace di spiegare la totalità dei fenomeni. Essa esprime la nostalgia dell’età dell’oro: della visione mitica, unitaria e convenzionale del mondo propria delle civiltà allo stato aurorale, quando uomo, natura e cosmo erano realtà inscindibili e la capanna costituiva, appunto, essa stessa una cosmogonia.

Non volendo essere innovatori, volendo anzi seguire pedissequamente le orme di quanti ci hanno preceduto, utilizzeremo anche noi la metafora della capanna primitiva per fornire una spiegazione convenzionale e una chiave di lettura sintetica di quanto abbiamo esposto fino ad ora. Accettando consapevolmente, s’intende, la sostanza critica insita in ogni metafora, e non potendo evitare di considerare il problema in termini scientificamente verificabili, con gli occhi di chi vive immerso in un mondo analitico, e che della visione intuitivamente onnicomprensiva delle cose non può non diffidare come retaggio di tempi meno incerti, ma anche più oscuri, di quelli attuali. Utilizzeremo la capanna allo stesso modo nel quale, nell’organizzare l’esposizione che stiamo concludendo, abbiamo preferito utilizzare dati concreti, gli edifici (siamo partiti dal fenomeno per arrivare alla lettura generale del problema), cercando di individuarne i principi formativi attraverso il confronto dei loro caratteri, piuttosto che definire a priori principi generali dai quali dedurre descrizione e interpretazione di problemi particolari. Una fondamentale differenza tra casa e capanna, tra cultura moderna e culture arcaiche, consiste nella concezione del tempo: noi pensiamo ad un tempo storico, ad una successione di periodi temporali che possono essere perimetrati, delimitati e racchiusi in una sequenza logica interpretabile. Nella visione dell’uomo primitivo o arcaico il tempo era continuo: al contrario dell’idea di storia come svolgimento ininterrotto di eventi, il riferimento di ogni suo atto, e quindi anche di ogni atto costruttivo, non era agli avvenimenti che si succedevano, ma a un’origine prima delle cose, a un atto generativo di partenza che doveva essere costantemente ripetuto. In base alle definizioni che abbiamo dato, questa constatazione riveste un interesse interpretativo fondamentale, perché indica nelle matrici elementari la presenza della manifestazione non solo più sintetica (unità assoluta nella concezione dell’organismo edilizio) ma anche più tipizzata e stabile delle forme costruite.

La modernità ha interrotto questo rapporto intenso con l’origine (non solo edilizia) delle cose, introducendo strumenti di interpretazione logico-analitici che hanno frantumato l’unità intuitivo-sintetica della conoscenza. Interpretazione, si badi, anch’essa storicamente necessaria, che non può essere semplicisticamente respinta cogliendo aspetti parziali di trasformazioni generali, ma che deve essere letta criticamente come momento dialetticamente necessario di un processo in atto. L’interesse, dunque, dello studio delle forme edilizie elementari ed originali, sviluppatesi secondo iterazioni divenute anche principi geometrici, non è per noi legato ad analisi di carattere storico e tanto meno etnografico o antropologico: esse riportano un’idea di spazio strutturatasi attraverso l’uso polarizzante del sistema binario (il diverso valore dell’alto rispetto al basso, del davanti rispetto al dietro, del verticale rispetto all’orizzontale) i cui principi hanno validità generale. Se il principio costruttivo dell’uomo primitivo era dunque quello della ripetizione (essendo rituale e stabile l’interpretazione dello spazio abitato, la nozione arcaica di tipo non contempla alcuna idea di progresso), l’uomo storico fonda la sua nozione di tipo sull’esperienza, dove la coscienza delle scelte acquista nel tempo valore crescente, procedendo per accumulazioni, dimostrate dalla progressiva complessità delle strutture architettoniche al termine delle diverse fasi storiche, fino al ciclico esaurimento dei principi che avevano generato le forme iniziali ed alla necessaria rigenerazione. La storia dell’architettura è, per questo, il portato vincolante di una lettura continua di esperienze acquisite, di antecedenti che condizionano l’operare: questo spiega il desiderio dell’uomo storico di liberarsi ciclicamente del fardello della storia che lo appesantisce, di ricercare il nuovo pur sapendo che, a rigore, il nuovo non esiste, che ogni edificio è sempre la conseguenza della lettura di una rilettura, fino ad arrivare alle matrici, alle forme aurorali. Periodicamente, dunque, ogni civiltà prova il bisogno di ricostruire le proprie forme originali: è il mito dell’eterno ritorno che attraversa la storia dell’architettura da quando il costruttore ha preso coscienza della propria storicità e, per quello che ci riguarda, della sostanza critica del lavoro dell’architetto nella società moderna. Un mito che continua a svolgersi nel cuore della modernità. Loos ha espresso in termini molto semplici e chiari il senso liberatorio delle forme originali, la loro necessità: l’architetto, buono o cattivo, costruendo una casa sul lago, finisce per deturparlo, il contadino no. Perché avviene questo? Semplicemente perché la coscienza spontanea del contadino “continua” la costruzione del paesaggio, compie gesti che già sono stati fatti. Il tetto che egli costruisce è parte costituente di una struttura più generale, di un mondo ordinato che si va trasformando e consolidando. “Un tetto bello o brutto?” si chiede Loos senza darsi risposta: semplicemente “Il tetto”1: la costruzione della copertura è legata ad una tradizione che libera dal problema della scelta del tipo e riuscirà certamente bene “come riesce ad ogni animale che si lascia guidare dal suo istinto”2.

Non si tratta, si badi, del mito del “buon selvaggio”, così come non è possibile ricostruire una “coscienza spontanea moderna”, ma di riconoscere il senso operante di nessi e legami. Perfino Le Corbusier, massimo tra i fautori dell’innovazione continua, nel parlare di ordine ritorna al tempo mitico in cui la casa è stata fondata per la prima volta attraverso i gesti elementari della costruzione della copertura-capanna (rappresentata da una tenda) e del recinto costituito da una palizzata. La nozione di spazio abitato non si evolve, è la stessa per la casa arcaica come per il tempio: “Non c’è l’uomo primitivo; ci sono mezzi primitivi. L’idea è costante, in potenza fin dall’inizio”3. Perfino Giedion, pur nel consueto parallelo con le arti figurative, riconosce il legame necessario dell’innovazione con l’origine primitiva delle forme: “Come la pittura e la scultura, essa (l’architettura contemporanea) deve ricominciare da capo. Deve riconquistare le cose più primitive, come se niente fosse stato mai fatto prima”4. A parte l’equivoco, palese e persistente, di voler legare con un filo continuo la prima casa prodotta dall’uomo all’ultima casa prodotta dalla macchina, le osservazioni di Loos, Le Corbusier, Giedion (ma si potrebbero citare anche Gropius, Pagano, Mercadal, Wachsmann, e tanti altri protagonisti dell’avventura moderna) fanno riflettere sulla durata dei miti di rifondazione, sulla loro incidenza nella formazione di molte teorie del moderno, costituendone spesso la faccia nascosta: il desiderio di tornare periodicamente all’origine delle cose al di là della storia, dare senso e giustificare la propria condizione riproducendo i gesti compiuti all’origine, è una delle caratteristiche dell’uomo civilizzato. L’uomo storico tende continuamente a rifondare il sistema di convenzioni in uso cercando di abolire il tempo passato, riproponendo come attuale la cosmogonia delle origini. Un sistema convenzionale che è anche, ma non solo, architettonico: si pensi al sabato giudaico-cristiano come riposo, interruzione e nuovo inizio, ai riti del Capodanno, diffusissimi in ogni parte del mondo civilizzato. L’uomo arcaico non aveva bisogno di scoprire di continuo la necessità delle rigenerazioni: quello che compiva con ogni gesto costruttivo era la riproposizione dell’atto fondativo, del momento mitico nel quale le forme tettoniche originarie erano state rivelate: ogni costruzione era assoluto ab initio che riproponeva l’istante iniziale depurato di ogni traccia di storia attraverso i simboli del centro, dell’asse verticale, dell’incrocio, del cerchio. Tutte le religioni arcaiche prevedono che la creazione nasca dal centro, legato all’ombelico del mondo. L’atto costruttivo è la creazione che si diparte da un centro, tanto da assumere forma di atto rituale, prevedendo ogni volta una nuova fondazione.

Così l’idea che l’uomo primitivo aveva della propria capanna era in qualche modo cosmogonia (come rappresentazione dell’ordine delle cose) e cosmologia (come spiegazione dell’ordine dell’Universo). Il centro è l’intersezione dove l’asse del mondo (simbolizzato, nei miti delle diverse civiltà arcaiche, dalla Montagna Cosmica che unisce cielo, terra, inferi, dal Pilastro centrale che sostiene i livelli cosmici, dall’Albero del Mondo) interseca la terra in un punto. Può sorprendere il pensiero logico che non esista, per l’homo religiosus delle società tradizionali, un solo centro del mondo e che per la costruzione di ogni nuovo edificio venga individuato un nuovo centro, ma l’uomo arcaico cerca costantemente il rapporto tra il particolare e la totalità, la coesione dell’universo attraverso la ripetizione delle stesse nozioni ad ogni possibile scala. In corrispondenza del centro, l’asse polare, l’Axis mundi, in origine leggibile in senso fisico attraverso il palo centrale, indica la posizione del nodo che lega l’edificio, ereditato in forma stabile nella memoria collettiva dei costruttori. L’intersezione degli assi orizzontali corrisponde all’orientamento, a partire dall’ingresso, individuando l’asse di percorribilità, e permettendo di distinguere le parti dello spazio, la destra e la sinistra di chi entra. L’altro carattere che permane nella storia dell’architettura è legato all’idea di perimetro espresso dalla forma immediata del cerchio. La nozione di centro e di circonferenza perimetrale era un dato permanente nella mente del costruttore perché legato all’atto fisico del costruire: il cerchio veniva tracciato a partire dal centro piantando un picchetto, costruendo con un compasso rudimentale costituito da una corda la circonferenza. Questa struttura elementare legata alla sequenza costruttiva dell’edificio è dunque costituita da assi, nodi, poli, il cui senso non è astratto ma concretamente costruttivo. Essa permane fino ai nostri giorni come dato strutturante qualsiasi spazio processualmente prodotto dall’uomo, palese negli organismi tradizionali, ma anche latente nelle opere più autenticamente moderne, purché si sappia riconoscerla.

La forma circolare della capanna elementare indica, in maniera simbolica, l’unità isolata dell’abitazione, la sua non aggregabilità: ogni capanna è un microcosmo autonomo, tendenzialmente incapace di produrre tessuto (si veda lo scarso rendimento dei tessuti ottenuti da matrici monocellulari circolari nei villaggi arcaici in Asia occidentale, ma anche nei villaggi nuragici in Sardegna, come Barumini, e negli stessi aggregati di trulli a pianta circolare in Puglia): un’interpretazione della costruzione come elemento autonomamente organico, unitario in senso totale. Ma, nel momento in cui l’unità abitativa si dispone, da organismo autonomo, a formare organismi di scala maggiore, aggregazioni di unità abitative, la forma circolare si trasforma, fase fondamentale di passaggio, in quadrilatera, originando la cellula elementare che tramanderà la scala umana agli organismi più complessi. Se la tenda appartiene al ciclo della pastorizia e della raccolta, e la capanna al ciclo agrario, la cellula elementare aggregabile appartiene al ciclo successivo: all’uomo sociale, che edifica la città secondo un ordine più complesso. La quale mantiene, tuttavia, la stessa idea di necessità nei rapporti tra le parti degli organismi edilizi più semplici: dalla forma elementare abitativa preriflessiva viene ereditata la fondamentale qualità genetica di “ricapitolazione” del sistema naturale di orientamento che, derivato dal bisogno dell’uomo di leggere e riprodurre l’ordine cosmico, ha valore a tutte le scale del costruito: la città antica come la domus elementare, la basilica come il foro, hanno anch’essi, come abbiamo cercato di dimostrare, il loro ordine binario di termini antagonisti e complementari, costituito da nodi e antinodi, assi di percorrenza accentranti e linee periferiche dividenti, all’interno dei quali la polarizzazione dei termini della diade introduce l’elemento dinamico, il verso, la direzione, l’orientamento. Questa eredità di pochissimi, fondamentali gesti, legata processualmente all’uso antropico del territorio, è ancora potenzialmente operante, sepolta sotto le incrostazioni che almeno mezzo secolo di smarrimento ha depositato sulla coscienza dei costruttori, e ancora capace di rigenerazione, di dare origine ad un nuovo umanesimo.

Nei caratteri degli edifici strutturati secondo una concezione dell’organismo ereditata dalle matrici del pensiero architettonico, dalla riflessione allo stato aurorale sul senso degli elementi e della loro aggregazione, può dunque anche essere letta, al di fuori di ogni interpretazione nostalgica e in un mondo inevitabilmente desacralizzato, la palingenesi che qualsiasi trasformazione vitale contiene, inizio e ultima permanenza potenzialmente ancora operante di una concezione sintetica ed unitaria del mondo, persa nei frammenti specializzati del pensiero moderno. Il poter risalire alle matrici formative dell’universo abitato attraverso il processo di modificazione che ne individua le tracce, il riconoscere la sostanziale, persistente organicità della realtà costruita che ci circonda, diviene così uno dei rari strumenti di continuità rimasti all’uomo moderno immerso in un mondo in cui nessuna continuità è più assicurata dall’atto che ripete gelosamente gesti tramandati.

Se il costruire è da sempre l’atto vitale (e non a caso in tutte le civiltà arcaiche ricorre la percezione che la costruzione possieda un’anima) capace di testimoniare il radicamento dell’uomo sulla terra, il suo operante senso processuale assume valore ancora più centrale, se possibile, nel cuore della tarda modernità, dove rappresenta l’ultimo riferimento stabile nel vortice di un universo precario e inabitabile “dove tutto quello che è solido si dissolve nell’aria”. Non si tratta, in altre parole, come vorrebbe certa letteratura nostalgica, di raccogliere e amplificare un’eco lontana attualizzando forme distanti nello spazio e nel tempo, ma di riconoscere le strutture profonde che sono ancora in grado di informare e rifondare gli edifici prodotti dai costruttori di fine millennio. Una storia operante, dunque, ma nell’accezione vasta del termine. Non una storia in perenne progresso che procede per gesti esemplari, sotto l’impulso salvatico di personalità creatrici, che avanza per opposizioni, paradossi folgoranti, innovazioni continue e radicali. La storiografia che ha proposto questa lettura delle cose, pur volendo essere dissacrante e innovativa, ha finito per essere conservatrice nel modo peggiore: riconoscendo puntualmente all’Unicità, all’Irripetibilità, alla Distanza il valore auratico che deve informare l’opera d’arte (assegnando, in fondo, alla storia il ruolo dogmaticamente didattico che le assegna qualsiasi ideologia della conservazione). Ma una storia come “processualità corale” basata sull’evidenza, sulla concretezza, sulla continuità del mondo costruito capace di strappare, per usare un’espressione cara a Pierpaolo Pasolini, ai conservatori il patrimonio della tradizione.

THE HERITAGE OF THE ROMAN SCHOOL OF ARCHITECTURE AND THE CANIGGIA’S NOTION OF ORGANISM

THE HERITAGE OF THE ROMAN SCHOOL OF ARCHITECTURE AND THE CANIGGIA’S NOTION OF ORGANISM

by Giuseppe Strappa

in: Gianfranco Caniggia Architetto, edited by Gian Luigi Maffei, Alinea, Florence 2003

  1. CRITICISM OF INTERNATIONAL MODERNISM

The figure of Gianfranco Caniggia, as a scholar and architect, must undoubtedly be studied inside the general background of continuity with his own cultural area, whose heritage – extensively dilapidated by Italian post-war architecture – was driven as much by “survivors” who contributed to the formation of the Roman School of Architecture between the two wars (Fasolo, Foschini and Piacentini) as by Saverio Muratori.

Saverio Muratori’s fundamental role in the formation of Caniggia’s thinking is fully dealt with in another part of this publication.

Our intention here is to develop certain considerations, already disclosed at the Cernobbio convention in July 2002[1], about Caniggia’s heritage from didactic experiments conducted by the Roman School of Architecture between the two wars, based on history’s new centrality in built environment interpretation and design and the architectural swing-back, foreshadowing “redesign”, tooled by planners and implemented by the built environment’s forming processes, through which the notion of organism is actually transmitted as an “integrated, self-sufficient correlation of complementary notions with a unitary aim”.[2]

A great deal has been written, especially during the post-war period but also in recent times, about the conservative standpoints of the original Roman School of Architecture, generally considered “academic” in its meaning of pedantic submission to traditional design forms and rules: didactics not abreast of rapidly changing times and design contrary to the spirit of modernism, equivocally identified as avant-garde for some time.

In fact Giovannoni, Fasolo and Milani, innovatively followed by Muratori and Caniggia, were perfectly conscious of conditions induced by modernity yet, like all classic thinker, they interpreted avant-gardism as a loss of rules and fragmentation of the basic unity of knowledge, clearly acknowledging its compounding of problems. In architecture, these fragmentations coincided with the irrational destruction of established values with intellectualistic and, therefore, unruly abstract experimentation.

They were fully aware of the true conditions of the modern crisis and, also, how it was impossible to repeat the archaic unity of things that had enabled the historic continuity of civil experiences, building cycles and decadence of forms.  They also knew that the world required new answers to up-and-coming, complex problems.  Yet they did not agree – and this is where they differ from the Modern Movement’s pioneers and their followers – on the accepted meaning of the crisis, faithful adaptation to new myths and noting of the desegregation irreversibility of every shared and authentic language.  Not to mention every style.  However, in the wake of major reformers, they did not surrender to the apparent evidence of objects by interpreting the built environment not as it appears but, according to their own design ethics, making interpretation converge with a transformation hypothesis that gave meaning to the built environment, unifying in the “thought which became architecture” the conscience of countless phenomena which otherwise appear as simple, dispersed fragments.

Giovannoni’s intuitions, Muratori’s major territorial visions and Caniggia’s interpretations of the organic transformation of basic building into specialized building are interpretations that not only imply design but are, themselves, design from many standpoints.

In Caniggia’s thought, the interpretation of modern succession (of critical conditions resulting from bewilderment vis-à-vis repeated, extended area exchanges, from the internationalisation of critical design tools, from the generalized serialization of forms and from the arising of new production modes) joined a current of thought originating from the criticism of contradictions arising from the radical split between reading interpretation and construction generated by the loss of the synthetic, unitary idea of organism.  Just in this radical split they recognised the formation of various tendencies in international modernity, starting  from the beginning of the century.

Fully comprehending how modern architecture cannot be traced back to a single corpus of design theories and tools, synthetically individuated through a presumed common language, Giovannoni raised the issue as far back as the Thirties. He opposed militant propaganda who tended to debase an unitary idea of the Modern Movement by sustaining the existence of numerous, contradictory forms of modernity, individuating the topic around which opposite design principles revolved in the discord between analytical technical and intuitive artistic components and in its direct upshot, individuated by the unsystematic relationship between structure (in the sense of static-structural system) and architectural form. The parallel transformation process of its technique and aesthetical principles, which enabled continuous exchanges among complementary disciplines, ended during the 19th century when the thread of stylistic continuity was broken between building and form and the two terms “seemed to belong to an organism that had lost its physiological balance”[3].

Giovannoni accused the split between architectural “imagination”, eclectic building and, above all, modernism at the beginning of the century for the fall of the “principle of truth” that has always been, during the course of history, one of the ethical rules that architects were called to obey, as proven by modern Roman architecture, unsupportive of innovative trends such as liberty that proposed such an indirect relationship between interpretation and typological character of architectural organisms as to leave the study of façades to other disciplines as visual arts and industrial design. Giovannoni did not reduce the “principle of truth” to a simple cause-effect relationship between static-structural solutions and spatial-pattern upshots, by introducing the implicit relational – and not mechanical – notion that averages form and building and which Caniggia then developed out rightly in his exposition on “direct and indirect” interpretation forms of architectural organisms, specially in his second volume on basic building design[4]. To oppose the simplifications of positivist trends, Giovannoni provided an implicit definition of the notion of interpretation that actually seems to foreshadow Caniggia’s thoughts, establishing the principle that the foundation supporting architectural composition must not only have an  “actual structural basis” as building rules provide precious means of expression in simple cases and, anyway, do not suffice in the most exacting applications. Structural nature must arise as a component or “general compositional sentiment” in the formation of the building’s general character, avoiding solutions that bare its body or even “display its skeleton”.

In fact, Giovannoni individuated the splitting of original design unity into various, specialized aspects of modern architectural thought by thinking about form and admitting how – in certain research series – indirect interpretability prevailed over direct interpretability of structural organisms,

The positivist line of thought was individuated in the sequence that originates in Schopenhauer’s assertions in Die Welt als Wille und Vorstellung on the disagreement between architectural weight and rigidity and that was developed with Viollet le Duc’s constructivist theories expounded in Entretiens sur l’Architecture and with Pugin’s assertions (considered, amongst other things, to disclose functionalist architectural interpretation) and ended with queries raised by new building experiments and by new materials answered by Modern Movement theoreticians, especially Le Corbusier in Vers une Architecture nouvelle, in aesthetical machinery and manufacturing terms.

Alongside this line of thought and in direct opposition to its apparent productive pragmatism, Giovannoni individuated a second set of theories that privilege (dimensional, geometric and chromatic) aesthetic rules actually linked more to physiology than to reason, an expected design principle. This line of thought was rooted in ancient theoreticians, who seemed to find new justifications in abstract art, true to the positivist meaning of architectural work, without any contemporary critic revealing its contradictions. Even though inexplicably Giovannoni – who had individuated in August Tiersch’s proportional theory the link between ancient treatises and modern design, does not exemplify the results of this different component of modernity in architectural practice – he evidently alludes to works such as Le Corbusier’s Villa Stein, where the town plan appears, free from any structuring reasoning, to exorcise the arbitrary nature of its façade composition by stating its hidden Muthesian derivation from Anglo Saxon picturesque  tradition.

The start of modern interpretation of the expressionist series, in opposition to “formal and objective” aesthetics based on geometric rules – the third group of theories that was also latent in ancient and Renaissance treatises – was grasped by Giovannoni, especially in studies on the use of psychology in interpreting Wölfflin’s artistic work, while a fourth group of theories was acknowledged in the work of those who derived architectural forms from the environment, intended as much to be an historic context as the nature of the place, clearly raising the issue – which lasted right throughout the second half of the 20th century, especially during the seventies and eighties – of its relationship with area references, often simplified in the internationalism-localism combination.

This interpretation of modern architecture is evidently the disruption of shared, original organic totality and Muratori’s interpretation of modern succession – as it was expounded during the period that coincides with the first critical elaboration phase of Caniggia’s thought – in his first post-war writings and in lessons imparted at the Roman Faculty of Architecture at the end of the fifties, retrieved and published by G. Cataldi and G. Marinucci in 1990[5].

Yet, at the same time, Giovannoni admitted how the theoretical innovations that characterized the Modern Movement, albeit with unexpected results, were an attempt to overcome the late 19th century eclectic drift in an endeavour to rebuild a new full design form.

Antinomy between modernist theories and the structural procedure that Giovannoni acknowledged, amongst other things, in manifest rational architecture: in fact, he does not out rightly refuse rationalism “that sticks to the principle of necessity and sufficiency” but the “unreasonable” rationalism that ends up by splitting design issues into structural “exaggeration” on the one hand and functional exaggeration on the other; the two sides end up by sticking to the same formal arbitrary principles of ecleticism,  including in design unity the remaining spontaneous component that enables art to be spoken about as “presumptive intuition” or “an early form of knowledge”[6].

The same fragmentation of other modernistic trends hid behind recent developments of rationalism: the technically exalted truth principle was actually contradicted by the lack of a general shared order and of a discipline that freed design from the changeability of fashions and from extemporary invention.

Right from initial syntheses during the forties, Muratori’s thought seems to extensively resume and develop certain issues raised by Giovannoni, not only by basically acknowledging lacerations in modern succession and including modernism among eclecticisms (environmental aestheticism) that had lost the order governing the unitary formation of architectural organisms but also reconsidering, more generally, the linguistic fragmentation that preceded the first world war as the origin of the crisis in modern language. Despite its moderation as compared to the excesses of 19th century eclecticism, this phase was an ambiguous passage in the history of architecture; disbelieving linguistic unity, it ended up by being an “anti-stylistic” period”[7].

Contrary to superficial, misinformed historiography that dichotomously separated academics from innovators, Giovannoni criticized modern and, therefore, perfectly updated, fertile internationalism, consciously included in the contemporary debate.  In other words, it is not a question “on the one hand of persons ignorant of the European cultural picture”, as Caniggia observed – nor of informed participants. If anything, the apparent independence of the former from diatopic architectural developments and the intentional upshot of their attention to the relative autochthony of experiences and of their continual reference to local participation compelling continuous critical choice to exclude modes and behaviours considered out of character with the place itself, to prefer outside experience and to assume facets in character with the Roman built environment”[8].

In keeping with this critical series developed between the two wars, Caniggia also accepted the basic historic need for the Modern Movement, admitting how it strove to bridge – despite contradicting aforementioned specializations – the gap between the interpretable form of buildings and aggregates and their relative building and fabric types: especially in basic building. The imitation of interpretability originating from specialized 19th century building was sometimes successfully overcome by part of modern architecture’s endeavour to swing-back to a comprehensible relationship between building (orientation of building parts, ceiling texture and layout of bearing walls) and external interpretability (hierarchization of apertures and expression of dwelling units in shells).

According to critical intuition that was already latent in Giovannoni’s thought, the Modern Movement was mainly accused of not having taken forming processes into account and, therefore, of professing aestheticism and being individualistic. However, these processes continued to operate also in wider spread modern architecture, in a sort of area inertia that could not be completely eliminated.  As in the case of Oud’s row houses in Kiefhoek, where façade walls are evidently not bearing and strip aperture seems to be rooted in the local language and in the flexible wooden origins of the Dutch area – despite its out-of-character flat-roof solution – or in the case of Fisker’s block in Copenhagen where obsessive holing seriality, indifferent to the dimension of underlying rooms, is made to originate from its wooden trellis construction and continual windows, even though the corner solution right around, more pertinent to masonry areas, seems to be out of character with local tradition.

 

  1. UPDATING THE NOTION OF ORGANISM

 

The innovativeness of the line of thought leading from the Roman School, which formed between the two wars, to Caniggia, can be assessed by comparing it to surrounding conditions in the context of the international debate on architectural design tools.  If related to European schools’ contemporary interpretation of disciplines such as the History of Architecture or Restoration, for instance, it is worth mentioning the Roman School’s great effort to renew them by restoring monuments, not just as a constituent part of architects’ culture but also as a way of extracting linguistic rules from the series of texts handed down by history.

Caniggia developed, innovated and systematized this heritage by introducing the issue of not only comprehending cultured monumental language but also basic building “dialect” to such an extent that he almost founded a new discipline – which becomes increasingly valuable the more we consider the cultural climate in which his didactic and design experiments were conducted – countered, with rare major exceptions, by confused reinterpretations of the past, intended as a morphological repertory for looting, or spent revivals of the Modern Movement’s principles[9].

In order to get to the bottom of this discipline, consider the founding role played by the teaching of history, continually updated by Gustavo Giovannoni and then Vincenzo Fasolo at the Roman School, during the pre-war period. In fact, this teaching was imparted not only though institutional courses on the History of Architecture but also through a real “didactic organism” necessarily pooled with courses such as Stylistic and Structural features of Monuments, imparted for many years by Guglielmo De Angelis D’Ossat as from 1937, basically true to Gustavo Giovannoni’s views and in the conviction that restoration, like all architectural operations, possesses inevitable critical and, all round, design material. This didactic organism was fundamentally boosted by Monumental Restoration teaching, imparted during the first year of the Regia Scuola di Architettura in via Ripetta in 1920-21, before it became a university faculty, by Sebastiano Locati, a teacher who played a brief, yet significant, role in linking up with Lombard research and the antecedents of Boito, who had taught him. Trained at the Brera Academy and then at the Milan Polytechnic School and an authority on Roman monuments’ organic features by directly surveying buildings, Locati proposed restoration based on rules analogically deducible from a stylistic comparison between synchronic works: restoration considered by his technical and artistic training as the synthesis of all architectural disciplines, by interpreting planner roles similarly to Giovannoni.  This teaching was then taken over by Giovannoni himself for twenty years until he stopped lecturing in 1943, testifying to the discipline’s founding role in the Roman school’s more general didactic design context.

For Giovannoni, didactic restoration of the work’s original organicity by interpreting typical transformations was actually a tool not only oriented towards restoration but, more generally, towards comprehending the forming processes of architectural organisms.  When faced with the problem of restoring a work of architecture, Giovannoni intentionally proposed – moving away from Viollet le Duc-style back-swings and with a surprising assertion of principle that, however, was perfectly consistent with his theoretical assumptions – that works could never actually be completely restored (note the affinity with Caniggia’s thoughts).

Therefore, it is clear how restoration was not just intended as study and safeguarding of the document’s historic and artistic aspects but also as a purely design operation which, like all design, is critical modification of the built environment and also restoration of the qualities of the organism intended, Caniggian style, as individuated type.

In fact, Giovannoni realised the specificity of the method used by architects to research other disciplines and how architects, “when they apply methods, fit for other arts, to architecture, also become amateurs and often presumptuous.”[10] With this background, history could not be considered as a tool of knowledge with independent aims but ended up by foreshadowing “operational history” that was forcefully proposed by the Muratorian school during the post-war period and whose capacity, especially in the field of the recovery, conservation and safeguarding of historic fabrics, restoration culture – as Gaetano Miarelli courageously called it – “was unknown or incomprehensible to it, let alone exploitable by it.”[11]

Lastly, drawing disciplines were to assume a vital function in the teaching of the history of architecture at the Roman Faculty[12]. In fact, drawing became not merely a communications and graphic transmission tool, as in schools for applied engineering, but above all a means of research and knowledge, linking history’s role to that of design[13].

As a result, according to a thesis that Giovannoni had developed some time back, architectural research was supposed to be “unitarian”, i.e. examining the phenomena that structurally and aesthetically combine unitarily to form the organism, and in terms of practical spatial and financial requirements, of external expressions and of its relationship with civilization and social conditions”[14].

The issue of teaching unity as essential to the organic synthesis expressed by design had already been raised by Giovannoni in 1907 with his proposal of the “complete architect”, who would have been trained though coordinated fields of study, each oriented towards “complete artistic training”: technical training “comparable, albeit in a narrower field, to that of civil engineers; independent study training produced by general culture “that could only be provided by a university”, and in-depth knowledge of architectural and art history”[15]. An idea resumed by Giovannoni on various occasions with his “complete architect” proposal, judging that – amongst advocates of “architecture as merely a branch of building science” and of “architecture as always, and above all, art with a capital A, which cannot be compressed by too many other notions” – architects have to be artistic experts who have acquired specific qualities not through “independent notions” thrown together but as expressions of unique thought, unique energy”[16].

In fact, the albeit remote origins of the Regia Scuola di Architettura di Roma paved the way for organic synthesis among disciplines, starting from the proposal put forward by the Commissione dell’Associazione Artistica to architectural scholars, also joined by Giovannoni, Magni and Milani, which envisaged teaching with four groups of disciplines unitarily converging: design based on architectural composition, academic drawing and decoration, science borrowed from polytechnic school teaching and history including restoration[17].

The origin and consequence of the new didactic method was the notion itself of organism around which Composition courses revolved.  In 1931, at his Architectural Course, Giovannoni wrote that architectural elements should compose “organisms that together can be considered structural in that they have to be practical, stable and distributive -consisting as they do of numerous elementary spaces interconnected through a determinate function – and aesthetic on account of the type of beauty adapted to the theme and to the environment that they have to adopt both outwardly and inwardly.

This notion of organism also formed the basis for technical teaching as in certain engineering school disciplines.  In this sense, Giovan Battista Milani played a major role in studying the stability of buildings.  In fact Milani, addressing the purely technical issue of design in his fundamental L’ossatura muraria (Turin, 1920), not only felt how it had to be referred to a more general rule of unitary need among parts of the building but referred to interpretations of both ancient and modern architectural organisms, which were the texts in which the etymons and rules of contemporary language had to be acknowledged.

During the post-war period, Vincenzo Fasolo continued teaching the History of Architecture based on the notion of organism and oriented towards design without, however, substantially updating the method and, on the contrary, acknowledging the contribution of 19th century French positivism treatises and, in particular, Choisy, Gustavo Giovannoni and Giovan Battista Milani, who clearly identified the relationship between structure and form. Yet Fasolo also stressed building interpretation, whose actual structural conception was not simply the way of materialising an architectural invention but formed an integral part of “expression” and the “utilitarian issue” solution. This interpretation did not simply coincide with the analysis of the visible part of the building yet, by resuming Muratorian school intuition, it also concerned its invisible part to the extent that – as ancient principles still applied to new artistic expressions – Fasolo suggested continuing decoration even in concealed building parts in order to “sense their existence even when they are out of sight” [18].

In his Guida metodica per lo studio della Storia dell’Architettura, pointing out the specificities of his teaching method as compared to others, he explains that the treatise addresses subjects “for our teaching aims and expands on building frames”. In fact, we have to realise how these buildings were constructed in various building materials, how spatial conquests were made and how stability relationships between parts of buildings materialised.  In other words, it is a question of analysing “the organisms” of buildings.[19]

At a critical stage for design disciplines and the role of architects, for Fasolo, works of architecture still manifest the degree of civilization achieved by a civil neighbourhood during a certain period in history.[20] Fasolo’s interpretation of history focused on design just as Gianfranco Caniggia’s interpretation of the built environment was design: interpretation as the dialectic synthesis between the subject’s intentions and capacity and the object’s attitudes[21]. The difference between “restoration”, as active reinterpretation of the lesson imparted by the monument, discovered by Caniggia at History of architecture courses during the early fifties[22] and “redesign”, as reconstruction of the forming process of buildings and building fabrics, is basically due to the new onus placed on the critical aspect of built environment interpretation.

During the fifties, some of Fasolo’s proposals on the static and spatial collaboration of components in forming architectural organisms – partially disclosed by Milani’s previous systematisation of matter – seemed to foreshadow thoughts processed by the Muratorian and Caniggian schools: see for instance the systematisation of matter proposed by G. Cataldi at the end of the seventies[23].

Fasolo evolutionary distinguished two major categories to which the same number of spatial systems corresponds: systems working out of gravity, without forcing, on continuous or discontinuous support (beam supported systems, mainly pertaining to ancient Greek, Egyptian and Persian civilizations) whose repeatability and seriality are implicitly individuated; systems working vertically and horizontally, and therefore, forcing, on continuous or discontinuous support (vaulted structures mainly pertaining to ancient Mesopotamian, Etrurian and Roman civilizations) consisting of more organic elements that differ in their structural duty, foreshadowing Caniggia’s definition of organicity as a “feature of aggregation consisting of elements that differ in their peculiar position and form and that are, therefore, unrepeatable and not interchangeable, just as each constituent element can be placed in one single position and in one single role within the aggregation, and has its own form and function, opposable and complementary to the roles, positions, forms and functions of other constituent elements.[24]

The static-structural system intervenes, unitarily with other components, also in determining various types of spatial systems: see, for instance, Fasolo’s distinction between central organisms with a heavy or elastic roof and central domed organisms, where the static-structural component does not so much erect the building as compose a linguistic and integral part of the type individuated in the design, together with its distributive and spatial system, whose nature depends on materials and their workmanship.

Caniggia openly refers to Fasolo’s renowned “nine Doric rows” leading to structural interpretation of the classic code; the nine rows (and eight underlying areas) indicate the origin of cultured language transmitted to monuments in subsequent eras by spontaneous building vernacular.[25]

If it is true that Caniggia’s demonstration of the link between profound linguistic etymons and the structural grounds that helped to form codes was probably inherited from Fasolo, albeit more intuitively than antecedent wise, it is worth mentioning – also to avoid debasing inexistent mechanical derivations – how the fundamental analysis of the organic (logical and process) relationship between fabric and building does not appear in Fasolo’s treatises and, more generally, in the Roman school’s historic interpretations before Caniggia’s thought.

Palazzo formation interpreted by Fasolo in subsequent transformations, starting from noblemen’s palaces, is still linked, for instance, to the traditional interpretation of Italian historiography whose version he provided in the second volume of Le forme architettoniche, edited together with Giovan Battista Milani[26]. And if, in Caniggia’s teaching, the interpretation of walls overlooking an inner courtyard – already proposed by Fasolo as the building’s real main façade – basically reappeared, Caniggia’s individuations have a radically different, innovative meaning: they are based on the assumption that palaces have to be interpreted as fabric specialization (“from the fabric and in the fabric”) and as an aggregate “overturned” in its routes inside the building, re-proposing all urban hierarchization features and ending up by explaining the substantial continuity of various building scales and demonstrating built environment data that appeared in Fasolo’s expositions as simple observations.

 

 

  1. REDESIGN

 

Despite lacking in the systematic nature that characterized Muratori’s post-war teaching, the method of comprehending the built environment through its swing-back interpretation, analysing relationships essential to the formation of structures collaborating to form the organism, shaped the teaching of the Scuola superiore di architettura di Roma right from its foundation, especially the teaching of disciplines that revolved more directly around the History of Architecture course.

In the ensuing debate, application of the decree of 31st October 1919 establishing the Regia Scuola superiore di Architettura, Vincenzo Fasolo went as far as proposing – in view of the new School’s opening months– that students’ entire training should be based exclusively on interpretation of the built environment, especially its specialized and monumental part and that the first three years should be entirely dedicated to studying the formation and transformation of architectural organisms to synthesize all the School’s teachings, which were to become real structures collaborating in the general didactic organism and unified by history. In fact, the study of the form of organisms had to combine the following curriculum: scientific-technical subjects, comprising analysis of the static arrangements of various structural systems; “general culture” subjects, which were supposed to explain the remote cause of transformations putting them into a more general – and not purely architectural – light; artistic subjects to make students familiar with the meaning of sets of decorations and, lastly, more compositional subjects which were to be imparted through stencils and exercises on “actual theme application” that was not supposed to repeat repertories but to “personalize” them.  Fasolo maintained that they all foreshadowed modern design, which was studied during the last two years of the course and that was, anyway, the upshot of a forming process whose need had to be proven by historic disciplines.  It is not hard to perceive this proposal that, despite arousing heated debates, met with a large following: the roots of the design-interpretation combination that then basically shaped Roman design didactics.

In Fasolo’s justifying of his proposal, the centrality of the notion of type is also explicit. In fact, the study of past organisms served less to traditionally divulge the history of architecture than to become familiar with how certain building forms were historically “necessary”, limited in numbers and could be updated to satisfy modern-day needs: “in architecture, as in life, invention is very restricted”[27]. Despite the aggressive extremism with which Fasolo put forward his proposal, he only met with the partial opposition of colleagues and Arnaldo Foschini, who held the course on Composition, raised reservations more of a practical nature than on principle.

The peculiarity of Fasolo’s History of Architecture teaching actually lay in his attempt to transmit to students his observation of architectural organisms as the result and unification of collaborating structures.  His lessons were conducted by graphically reconstructing detailed elements of the building before structurally and spatially linking them until they represented the whole organism, almost as though the teacher’s task was to design a new organism starting from the tools of a certain civil phase in the presence of students, aided by legendary graphic capacity.

Therefore, reconstruction of the architectural work’s features through surveys also became interpretation or retracing the monument’s forming process with measuring and dimensional ratio tools, on which building type study conferred a meaning and content. Giovannoni deliberately concluded his inaugural speech at the new School of Architecture by praising the function of surveys as a didactic tool oriented towards design, whose “main experimental aid will be the practical survey of local monuments, be they noble or humble, in order to comprehend their type and meaning by dissecting them, back tracing the path followed by the architect and planners who composed the organism and shaped its elements: starting from plans and their structural layouts (that only those who do not understand architectural conception can consider superfluous) as far as designs and decorations on their facing.”[28]

Yet redesign practice also has a remote origin that does not necessarily coincide with that of historic studies: it is not only professionally and didactically customary with Roman monuments but also with restoration’s particular guidance, provided by study tradition and interventions on ancient moments (just think of the numerous antecedents exemplified and compounded by Piranesi), as the main didactic tool.  When modern design procedure saw analytical-technical components progressively breaking away from intuitive-artistic components, the general knowledge essential to architects’ training, monumental study, became a discipline that – professional aims aside – fulfilled its fundamental educational task, not only with a unitary view of the design of various building components but also to synthesize forming process, which presided over architectural composition and were individuated in the substantial continuity between interpretation and design. Architects’ interpretation is never inert verification and reading up on the built environment but, even more than a traditional driving force, it is design that involves their critical conscience and selective and interpretative capacity, according to a method that has continued at the Roman School of Architecture virtually to date.  Therefore, the monument’s history and development stages had to be “swing-back tested”. More generally speaking, restoration was intended as a critical, fundamentally design, act that restored the work and not the series of fragments handed down by history. It studied how the element testified to a structure of relations that originally linked it to other indispensable elements.  And this structure – like, to a greater degree, systems and inherited organisms – can only be recognisable by comparing it to other structures and similar systems.

This modern monumental restoration[29] conception also propitiated the formation of a new connotation of the notion of type as a set of historically individuated laws and rules that determine a typical relationship among elements, structures and systems combining to form the architectural organism.

From many standpoints, redesign proposed at Caniggia’s courses (in Genoa, Florence and Rome) inherited, updated and upgraded the foregoing: history as swing-back processes still under way both on building and on building-aggregate scales; restoration as rediscovery of the built environment’s charter laws not so much of monuments as basic building aggregates, apart from compensation for damages caused by a culture out of character with the inherited features of the town and territory. Restoration is not, therefore, just conservation of the artistic and documentary value of individual building works or aggregative organisms: it is recouping their value as organisms reconsidering the relationship between “authentic”, “false” and “integration” and legitimising the reconstruction of an albeit unauthentic text that, like the copy of a manuscript, certainly does not retain its original, but its literary, value.

Where monuments were not simple ruins but “live, complete organisms” it is worth remembering how Giovannoni insisted on restoration “that restores their harmony”.[30]

Therefore, historic cities became texts that safeguarded linguistic origins and in which daily vernacular laws had to be recognised, tracing back “concealed architecture” and grasping process symptoms that could still enable design in character with the inherited building culture[31].

Filtered through fundamental experiments conducted at courses held by Muratori in Rome as from the 1961-62 academic year on redesign of historic fabrics such as Tor di Nona but also on contemporary fabrics like Centocelle, experiences proposed by Caniggia to students tended to “asymptotically” approach, through successive approximations, the real built environment process gradually conquered by its critical process through interpretation.

Interpretation that gave rise to a design method which, directly derived from the built environment, avoided the shortcomings and risks of the ideology that largely contributed to the disaster of modern architectural theories.

Giovannoni had already schematically raised this issue by acknowledging how theory ends up by having independent grounds and upshots from design: “Theory runs its own course, tracing its own rigid forms and expounding its own unilateral cocooned philosophy; reality often goes its own way but this net difference in thought and process does not lead to formal dissention. On the contrary, a tacit agreement seems to have been established to enable artists’ freedom of action, elegantly feigning in order to make them humbly accept the lofty principles with which theory intends to guide them.  The laborious evolution of art requires a layer of dead leaves to conceal and protect new germination.”[32] This observation concerned the issue of interpreting past works, for which they continued to use (arousing renewed criticism of Muratori and Caniggia) theoretical art history tools, without taking into due account their features as organisms (plans, structural reasons).

In fact Giovannoni, unlike Caniggia who based himself on Muratori’s systematisation of matter assumptions, arrived at the notion of aggregative organism through successive approximation, progressively abandoning wide sweeping theories. If Giovannoni’s initial spacing-out theory proposed an abstract idea of fabric, in time it evolved by taking into account the features of the environment surrounding the moment and its historic and artistic value: if properly designed, new spatial and route-hierarchization brought about by “systematisation” could lead to updating the urban aggregate, according to new polarizations. In other words, albeit far-removed from Caniggia’s procedure and contemporary positions also in northern European modernism, that isolated historic buildings, even dwellings, from their pertinent lot. Giovannoni progressively approached a building aggregate idea as individuation of a more general typical law, i.e. of fabrics.  In addressing the brand new “cinematic city”, Giovannoni sensed the latent developments of this notion on an urban scale, as an alternative to town planners’ widespread belief that they could split towns into single-functional, specialized parts and separate the zoning principle from the idea of urban form connected to building design: “tracing road sections without knowing whence they could lead or laying tramway lines or metropolitan undergrounds without taking their building function into account expresses empiricism as opposed to rational conception”[33].

Yet, affinities and derivations aside, also in the light of subsequent studies, sources and antecedents, Caniggia’s research on the formation of fabrics and their transformations and specializations must be acknowledged as being surprisingly original and unequalled in Italian schools of architecture. Differences in method with parallel Italian typological research have been fully investigated. However, analogies were recently found with studies conducted by geographers who, when Caniggia was commencing his research, felt the need to extensively renew territorial surveying tools and start investigating urban morphological issues.  In England, the German geographer M.R.G.Conzen, a lecturer on Human Geography at Newcastle upon Tyne University, experimented on the town of Alnwick a town plan analysis method, based on the process of lotting and then aggregating into blocks updated by a streets system. Conzen proposed an interpretation method oriented towards restoring a forming process, apparently unknown to Caniggia[34] and based on the general hypothetical behaviour of medieval urban tissues, analogous to Caniggia’s thought on progressive building-type updating and contemporary permanence of systems and fabric[35]. Yet Caniggia’s research also differed from these studies on account of his synthesis on different scales, whose substantial continuity was acknowledged, starting from the notion of territory, which also originated from initial street hierarchization, to building organisms – giving rise to the distinction between basic and specialized building – but also of their unity, through the “cellular nature” of fabrics and typological continuity.

 

  1. AESTHETIC SYNTHESIS AND THE NEW NOTION OF STYLE

 

With the course of events at the Roman School of Architecture between the two wars, the term “expression” meant the architect’s effort to synthesize formal unity, “the end result of architectural conception”[36] in opposition to contemporary designers’ individualistic versions but also to research methods used in architectural historiography at the time which, under the influence of Adolfo Venturi’s criticism professing aestheticism, tended to privilege architects’ individuality and the exceptionality of works.

Despite superficial and, anyway, far-removed affinities with the 19th century French school, the restoration didactic issue ended up by involving the definition itself of “style”, intended as much a built-environment interpretation tool as a design tool.  The restoration issue was raised innovatively not to interpret style, intended as choice of individual expression and the artist’s visible peculiarities, but to historically comprehend the organism’s essential features to the extent that the “real form” of the monument could not paradoxically coincide with its original form.

The new onus placed on structural features synthetically individuating the system of building organisms is indicative of breaking away from art historians’ methods and definitions: instead of the accepted meaning of the term “style” as a language used in works (in architecture as in painting or sculpture) and traced in ornaments, particulars and details, its definition implicitly ended up by acquiring, also through De Angelis D’Ossat’s teaching in Caratteri stilistici dei monumenti, new connotations and meanings, foreshadowing Caniggia’s systematisation.

As far back as 1920 Giovannoni wrote, “Style is not architectural crystallization but a series of stages in a continual flow, a series of groups of forms, whose temporal and local evolution often proceeds irregularly with adaptations and evolutions; style is not a sporadic plant that ‘germinates like spelt grain’.  It only germinates with special soil conditions for various permanent or changing, material and historic, ethnographic and social reasons and it is essential to know these causes in order to learn its artistic and structural characteristics and to get its gist and meaning.”[37]

This different conception of style – linked to a latent notion of process and the synthetic idea of structure that binds collaborating parts, expressed and interpretable through a language common to civil environs and pertinent to a determinate historic phase – induced the design of ancient organisms, their restoration and interpretation in a new form: bare, essential and often stripped of details, individually linking the design and interpretation of ancient works to Roman late twenties and early thirties modernist architecture, in which modernity appears as simplification, updating and stripping of inherited organisms.  Therefore, this combination of interpretation and design in one single graphic gesture seems to illustrate how the splitting of architecture into disciplines as a didactic contrivance is evident from students’ drawings at Fasolo’s courses on History and architectural styles during the thirties: bare assembly sketches, mass-produced drawings and building frames simplified in order to recognise internal organic relationships, where the “patterns” of basilicas and ancient thermal baths alternate with the “visions” of Greek and Roman architectures.

Saverio Muratori had already picked up the new meaning of the term “style” during the post-war period.  Contrary to its generally accepted definition, in 1944 Muratori started re-proposing an accepted meaning, distilled from pre-war experiences, of the term as the unifying rule that presides over action, sensing its bond, which was subsequently developed with the notion of organism and organicity: compositions (reference to contemporary architecture is evident) where elements aggregate without unifying are not stylistic whereas “architectures that explicitly express their structure, i.e. their structural energy, influence us by introducing us to action organicity, stress coordination and an attitude on which style is based”[38].

Even more so today, this new definition seems to be the most evident upshot of a continually updated, profound, ancient heritage, which was handed down to us through Roman didactics during the first half of the past century and innovated by Muratori and his school: in opposition to style intended as “manner, peculiar egocentric form of a certain personality, school, nation or time and, worse still, academy or prearranged stylistic formulary…”[39]. Therefore, style became “absolute reality, recognisable in the collaboration, articulation and synthesis among individual parts, foreshadowing the unity-distinction principle that was then developed in Architettura e civiltà in crisi.

 

These brief notes on his relationship with modern Roman tradition between the two wars will perhaps help to explain how according to Caniggia – who was the most innovative and, at the same time, faithful interpreter of that universe of ideas and thought – the multiple built-environment forms washed up by history could not simply be classified and scientifically processed as in the series of typological studies generated by Giulio Carlo Argan’s analysis.

According to pre-modern principles, Caniggia sensed how it was necessary to extract hidden, deeper meanings from objects: the world inhabited by man, houses as monuments, thus became not just simple construction but textes and designer-architects had to be capable of interpreting the message conveyed by the text, and also of deciphering not only what the built environment appeared to be but how it should be.

Therefore, in this, Caniggia seems to have inherited, and transmitted, the Roman school’s deeper and more authentic teaching. With his capacity to grasp what was individual and to recognise its vital belonging to the more general, living anthropic environment, he ended up by restoring it for us as a constituent and inseparable part of a shared heritage.

[7] The theses that he asserted at his lessons during the fifties are basically disclosed in his works Storia e critica dell’architettura contemporanea (1944) and Saggi di critica e di metodo nello studio dell’architettura (1946), in S.Muratori, Storia e critica dell’architettura contemporanea, Roma 1980, published by G.Marinucci.

[9] Chronologically, the general study of the relationship between “dialect” as a product of spontaneous conscience and “cultured language” as the product of critical conscience started from Caniggia’s studies on territory, intended as an organism comprehensive of all degrees of anthropic transformation.  As part of Saverio Muratori’s teaching, Caniggia held, during the 1965-66 academic year, a course on Surveys – design of territorial structures, which included the study of “deduction and reinterpretation from structures and typical organisms and from individual and environmental processes of typical territorial constants and their application” (Cf. Programma dei corsi e attività di Istituto, Istituto di Metodologia architettonica dell’Università di Roma, Facoltà di Architettura, Roma 1965-66.)

[12] On the history of the Roman Faculty of Architecture, see not only the volume by V. Franchetti Pardo, La Regia Scuola di Architettura di Roma, Roma 1932 but also L.Vagnetti and G. Dell’Osteria (by), La Facoltà di Architettura di Roma nel suo trentacinquesimo anno di vita, Roma 1955. Particular significance in comprehending didactic design lies in Prolusione inaugurale della nuova Scuola Superiore di Architettura, read by Giovannoni on 18th December 1920, and the publication of Discussioni Didattiche (in G.Giovannoni, Questioni di Architettura, Roma 1929), where Giovannoni refers to the design didactics debate held in via Ripetta classrooms in 1920.

[13] This didactic tradition also had a large following in Muratorian and Caniggian schools. Refer to the didactic text used during the first courses at the Faculty of Architecture in Reggio Calabria: R.Bollati, S.Bollati, G.Leonetti, L’organismo architettonico. Metodo grafico di lettura, Firenze 1990.

[34] Caniggia knew and appreciated studies by the Italian geographer Renato Biasiutti who established, in 1938, a series of studies on Italian country-houses published by Leo S. Olschki in Florence.

[35] “In the process, however, the plan and fabric of the town, representing as they do the static investment of past labour and capital, offer great resistance to change. New functions in an old area do not necessarily give rise to new forms. Adaptation rather than replacement of existing fabric is more likely to occur over the greater part of built-up area established in a previous period.” (M.R.G.Conzen, Alnwick, Northumberland. A Study in Town Plan Analysis, London 1969, page 6).
