Giuliano & Francesco Giamberti da Sangallo Piero di Cosimo (1462–1522)
In these pendant portraits, the Florentine architect Giuliano da Sangallo is portrayed with his recently deceased father Francesco, who was a musician as well as an architect. These two panels are among the earliest examples of portraits in which the sitter’s vocation is central. The quill and compass denote architecture, the sheet of notes refers to music: both arts are based on harmony and proportion.
