Jacopo d'Antonio Sansovino (2 July 1486 – 27 November 1570) was an Italian Renaissance sculptor and architect, best known for his works around the Piazza San Marco in Venice. These are crucial works in the history of Venetian Renaissance architecture. Andrea Palladio, in the Preface to his Quattro Libri was of the opinion that Sansovino's Biblioteca Marciana was the best building erected since Antiquity. Giorgio Vasari uniquely printed his Vita of Sansovino separately.
