Italian medallist and sculptor (also known as Camelio), son of Antonio di Marco Gambello, architect and sculptor. He studied drawing under Giovanni Bellini. The earliest references to him document his employment as maestro della stampe at the Venetian Mint in 1484. He perfected a method for stamping medals in high relief rather than casting them in sand or by the lost-wax process; this allowed the easier production of medals in larger editions. //
