Beside his profile portrait by Lazzaro Bastiani, Foscari commissioned a bas-relief bronze plaquette from Donatello, which survives in several examples. His figure kneeling in prayer to St Mark figured over the portal to the Doge's Palace until it was dismantled by order of the revolutionary government, 1797; the head was preserved and is conserved in the Museo dell'Opera di Palazzo Ducale. His monument by the sculptor Antonio Bregno in collaboration with his architect brother Paolo was erected in the church of Santa Maria dei Frari in Venice.
