Ruberti, Giovanni Francesco
Works of Art
Ruberti has been identified as a young goldsmith first mentioned in Mantua and called gentil maestro on 12 February 1483. He was then recorded as working on arms intended as a gift to the Sultan of Turkey, and as beginning to strike coins by an improved method in March 1492. He was sent to Milan in 1517, and to Venice in 1497 and 1526; was recorded as master of the mint at Mantua; and continued to work for the court until at least 1526.
The medal of Francesco II (NGA 1957.14.663.a,b) is the only medal signed by Ruberti. A large group of plaquettes, signed IO.F.F., formerly was ascribed to the artist.
