Italian medallist, glass painter and die engraver. He was one of the most prolific and able medallists of the Italian Renaissance, producing around 200 medals. He held various official positions including several in the mints of Emilian courts: in Ferrara (1554-59), in Bologna (1572), in Novellara (1574) and in Florence (1576). In Florence he was 'maestro di stucchi' under Grand Duke Francesco de' Medici (1541; 1574; 1587). He was also renowned as a portraitist in coloured wax for which he apparently developed new materials and techniques to represent hair and skin. //
