Jacopo Sansovino (1486–1570), also an important sculptor, was a Florentine with a successful career in Florence and then Rome. He fled to Venice after the catastrophic Sack of Rome in 1527 and in 1529 was appointed chief architect and superintendent of properties (Protomaestro or "Proto") to the Procurators of San Marco. Before long he found a style that satisfied Venetian patrons and was "definitive for the entire subsequent history of Venetian architecture". He created the appearance of much of the area around the Piazza San Marco beyond Basilica of San Marco itself, designing the Biblioteca Marciana (1537 onwards) and mint or "Zecca" on the Piazzetta di San Marco. His palazzi include Palazzo Corner della Ca' Grande (1532 onwards) and Palazzo Dolfin Manin from 1536.
