Alessandro Leopardi
Alessandro Leopardi (c. 1465–1522/1523) was a Venetian sculptor, bronze founder and architect, nicknamed del Cavallo after his most famous work. A master at the Venetian mint, he was exiled for fraud in 1487 but recalled in 1490 to cast the bronze equestrian statue of Bartolomeo Colleoni, left unfinished at Verrocchio's death. Verrocchio had made the clay model, but the Venetians chose Leopardi; casting was completed in 1492 and his pedestal in 1495.
He also designed and cast the three bronze flagpole bases in St Mark's Square between 1505 and 1506, and later oversaw fortifications at Padua and Treviso.
