an Italian sculptor of international outlook who travelled in Italy, Germany, Austria, France, Spain and the Netherlands. Leoni is regarded as the finest of the Cinquecento medallists. He made his reputation in commissions he received from the Habsburg monarchs. His usual medium was bronze, although he also worked in marble and alabaster, carved gemstones and probably left some finished work in wax (in which many of his sculptures were modelled), as well as designing coins. He mainly produced portraits, and was repeatedly used by the Spanish, and also the Austrian, Habsburgs.
