This portrait has an informal, private character and was probably meant as a gift for a friend. The sitter's cap is the type a nobleman would don at home when not wearing his wig. Ghislandi, the greatest Lombard portraitist of his age, was a lay brother of the Order of the Minims. Fra Galgario was his nickname, referring to the monastery of Galgario in the city of Bergamo with which he was associated.
