On the left are the Correr (Corraro) coat of arms. Despite the indications in the inscriptions, it is difficult to identify the sitter with any known Antonio Correr, son of Vittore Correr. Their wording has probably been repainted wrongly. The sitter could be Vittore Correr (1658 - 1714), who became Procurator of S. Marco in 1685.
