This essay examines Giovanni Montiroli’s 1871 survey of San Salvatore in Spoleto through two sets of drawings that reveal the dual nature of architectural representation. The first consists of precise survey sheets documenting measurement and form; the second includes five expressive presentation drawings derived from them. Their comparison, supported by parallels with other works by the architect, shows how survey drawing adapts to different technical and editorial contexts. Set in the late 19th century, the study highlights Montiroli’s interpretive approach, informed by his collaboration with Luigi Canina, and its lasting value for later research on the monument. Giovanni Montiroli clearly views drawing as an essential tool for knowledge. His critical approach goes beyond the simple representation of the current state of affairs to become a tool for cognitive analysis, detached from any form of flattening and graphic regularisation inclined towards an idealised representation of the monument, towards which he shows in-depth historical knowledge, analysing its spatial articulation, technical and construction characteristics and the use of different materials. With his ability to “see architecture” down to the smallest detail, providing information even on the state of deterioration of the material surface, Giovanni Montiroli leaves behind a rare graphic documentation of extraordinary value to those who subsequently ventured into the “discovery” of the Basilica of San Salvatore.
Questo saggio indaga il rilievo di San Salvatore a Spoleto realizzato da Giovanni Montiroli nel 1871 attraverso due serie di disegni che rivelano la duplice natura della rappresentazione architettonica. La prima è costituita da tavole tecniche di rilievo che documentano la misura e la forma; la seconda comprende cinque disegni espressivi di presentazione derivati dalle prime. Il loro confronto, supportato da riscontri con altre opere dell’architetto, mostra come il disegno di rilievo si adatti a differenti contesti tecnici ed editoriali. Collocato nella seconda metà del XIX secolo, lo studio evidenzia l’approccio interpretativo di Montiroli, maturato anche attraverso la collaborazione con Luigi Canina, e il suo valore duraturo per gli studi successivi sul monumento. Giovanni Montiroli considera chiaramente il disegno uno strumento essenziale per la conoscenza. Il suo approccio critico supera la semplice rappresentazione dello stato di fatto per divenire uno strumento di analisi cognitiva, estraneo a qualsiasi forma di appiattimento e di regolarizzazione grafica orientata verso una rappresentazione idealizzata del monumento. Al contrario, Montiroli dimostra una profonda conoscenza storica dell’edificio, analizzandone l’articolazione spaziale, le caratteristiche tecniche e costruttive e l’impiego dei diversi materiali. Grazie alla sua capacità di “vedere l’architettura” fin nei minimi dettagli, fornendo informazioni anche sullo stato di degrado delle superfici materiche, Giovanni Montiroli lascia una rara documentazione grafica di straordinario valore per quanti, in seguito, si sono dedicati alla “scoperta” della Basilica di San Salvatore.

Abstract
This essay examines Giovanni Montiroli’s 1871 survey of San Salvatore in Spoleto through two sets of drawings that reveal the dual nature of architectural representation. The first consists of precise survey sheets documenting measurement and form; the second includes five expressive presentation drawings derived from them. Their comparison, supported by parallels with other works by the architect, shows how survey drawing adapts to different technical and editorial contexts. Set in the late 19th century, the study highlights Montiroli’s interpretive approach, informed by his collaboration with Luigi Canina, and its lasting value for later research on the monument. Giovanni Montiroli clearly views drawing as an essential tool for knowledge. His critical approach goes beyond the simple representation of the current state of affairs to become a tool for cognitive analysis, detached from any form of flattening and graphic regularisation inclined towards an idealised representation of the monument, towards which he shows in-depth historical knowledge, analysing its spatial articulation, technical and construction characteristics and the use of different materials.
