Italian goldsmith. The first reference to Ugolino is in 1329 when he and his sons, Ugolino the younger and Giovanni, sold a house. In 1332, Ugolino received compensation in connection with the commission of a chalice that the Comune of Siena was to give to the condottiere Guidoriccio da Fogliano. In 1337-38 Ugolino produced his most important work, the magnificent reliquary of the Santo Corporale (Orvieto Cathedral). The inscription on the reliquary states that it was commissioned by Bishop Tramo Monaldeschi and the canons of Orvieto Cathedral during the pontificate of Benedict XII. It was probably manufactured in Siena; payments date from 7 May 1337 to 27 December 1339, and the total cost was 1374 and a half gold florins. //
