Sforza, the son of Bianca Maria and new Duke with Bianca Maria as regent. Zanetto's commissions begin to reflect the wide array of contracts expected from a court portraitist of the time. Bugatto worked not only as a painter but as a designer of medals and coins, including designing the portraiture used on ducats with Duke Galeazzo and regent Bianca. In particular, Bugatto is arguably credited with designing or overseeing the official image of Galeazzo in 1467 for a new series of ducats which were to have only the Duke in preparation for his investiture. In 1468, Bugatto was sent to Paris to paint a portrait of Bona of Savoy, sister of the Queen of France Charlotte of Savoy, and intended bride of Galeazzo Maria Sforza. The trip to Paris was also financially beneficial for Zanetto Bugatto, who brought with him a portrait of Francesco and Galeazzo Maria Sforza, which he sold to King Louis XI of France. From 12 November 1470 to 3 March 1471, upon his return to Milan, Bugatto was involved as a designer in the creation of ten solid gold medals for the Duke and Duchess of Milan. In 1471 Duke Galeazzo and Duchess Bona of Savoy spent a month long visit in Mantua where they sent for Bugatto to meet them. They spent three days in Mantua, arriving on 19 July 1471 and leaving two days later. While there Bugatto saw and studied the artist Andrea Mantegna's work. In 1472 Bugatto worked with Bonifacio Bemo and Leonardo Ponzoni to create his last known completed work, frescos in the Santa Maria delle Grazie located outside of Vigevano. The chapel is now destroyed. In 1473 Bugatto was commissioned to paint a portrait of Duke Galeazzo, Bona of Savoy, and their child for the choir of San Celso, Milan. It is assumed Bugatto died in 1476, though the exact date, how, and where remain unknown. Records remain of him up to 1476 and it is known that in this year Galeazzo attempted to find a replacement court portraitist. At the suggestion of his ambassador in Venice, Leonardo Botta, Galeazzo wrote to hire Antonello da Messina who also worked in the Flemish-style as Bugatto did. However, the Duke was assassinated in 1476 shortly after and there is no record of da Messina ever accepting Galeazzo's patronage. Education Bugatto studied for three years under Rogier van der Weyden in Brussels
