This exceptional diptych shows the leading Florentine architect Giuliano da Sangallo and his recently deceased father Francesco, who was an architect as well as a musician. These are among the earliest portraits to characterize their sitters by profession: a pen and compass allude to architecture, the sheet music to music. Both disciplines are based on notions of harmony and proportion.
