The architectural theory of Carlo Lodoli emerged from a critique of 18th-century design, where he advocated for forms derived strictly from the inherent properties of construction materials. Operating within the Republic of Venice, he challenged the decorative excesses of the Baroque and Rococo periods, proposing instead a rational architecture grounded in scientific principles and structural integrity.
Early Life and Education
Born in 1690 in Venice, Lodoli originated from a family with professional ties to the Venetian Arsenal and military engineering. In 1706, he began his religious training as an Observant Friar Minor in Dalmatia. By 1709, he relocated to the monastery of Santa Maria in Ara Coeli in Rome. During this four-year period, he engaged in studies of philosophy, theology, Greek, French, and science, which informed his later architectural perspectives.

Between 1715 and 1720, Lodoli resided in Verona, where he taught mathematics, astronomy, and physics to local noblemen while instructing monastic novices in philosophy. He also collaborated on an edition of the works of Marcus Antonius Muretus and forged significant friendships with Francesco Scipione Maffei and Angelo Calogerà. Upon his return to Venice in 1720, he lectured on theology and held the position of historian for the Franciscan Order.
Architectural Theory and Practice
Lodoli maintained that the function of a building must dictate its form, arguing against the imitation of timber-based classical orders when working with stone. His concepts relied on the honest use of materials and the scientific rigor found in physics, a discipline he believed should guide civil architecture.
Legacy and Records
Because Lodoli never published his own writings, his influence persists through the documentation of his students and contemporaries. Andrea Memmo detailed Lodoli’s theories in the 1786 volume Elementi d’architettura lodoliana, while Francesco Milizia incorporated these ideas into his 1781 treatise. Lodoli died in Padua in 1761, leaving behind a legacy as a pioneering theorist who anticipated modern functionalist principles.

What was the main criticism Lodoli leveled against classical architecture?
