Palladio's closest follower
Vincenzo Scamozzi (1552–1616) was an architect from Vicenza and Palladio’s closest follower. He inherited Palladio's unfinished projects after his master's death (including the Teatro Olimpico in Vicenza) and took his ideas to classicizing extremes, notably in the Procuratie Nuove. He had only one pupil, but he was a gem: Baldassare Longhena.
Outside of Italy he was perhaps best known for his treatise L’Idea dell’Architettura Universale (The Idea of a Universal Architecture), said to be very last of its kind in the Renaissance just before everything went Baroque, which he published in Venice the year before he died. His ideas went into hibernation but would later influence Neoclassicism.
