The Four Doors Room was the formal antechamber to the more important rooms in the palace, and the doors which give it its name are ornately framed in precious Eastern marbles; each is surmounted by an allegorical sculptural group that refers to the virtues which should inspire those who took on the government responsibilities. The present decoration is a work by Antonio da Ponte and design by Andrea Palladio and Giovan Antonio Rusconi. Painted by Tintoretto from 1578 onwards, the frescoes of mythological subjects and of the cities and regions under Venetian dominion were designed to show a close link between Venice’s foundation, its independence, and the historical mission of the Venetian aristocracy. Amongst the paintings on the walls, one that stands out is Titian’s portrait of Doge Antonio Grimani (1521–1523). On the easel stands a painting by Tiepolo portraying Venice receiving the gifts of the sea from Neptune.
