Duomo of Milan in the context of "Milanes"

Gian Galeazzo Visconti (16 October 1351 – 3 September 1402), was the first duke of Milan (1395) and ruled that late-medieval city just before the dawn of the Renaissance. He also ruled Lombardy jointly with his uncle Bernabò. He was the founding patron of the Certosa di Pavia, completing the Visconti Castle at Pavia begun by his father and furthering work on the Duomo of Milan. He captured a large territory of northern Italy and the Po valley. He threatened war with France in relation to the transfer of Genoa to French control as well as issues with his beloved daughter Valentina. When he died of fever in the Castello of Melegnano, his children fought with each other and fragmented the territories that he had ruled.

The Zavattari were a family of Italian painters active in Lombardy from the 14th to the 16th century.

Cristoforo and Franceschino Zavattari are known as collaborators to the decoration of the Duomo of Milan in the early 15th century. The family's masterwork are the frescoes in the Theodelinda Chapel in the Cathedral of Monza, work by Ambrogio and Gregorio Zavattari (1444). Unusually in fresco, the gold sky is patterned in relief pastiglia plasterwork. Some attribute this work to Troso da Monza.Subsequently, Franceschino and his sons worked at the Certosa di Pavia, where they conserve a fresco depicting the Madonna, and the church of San Lanfranco in Pavia.
