This is an examination of the role of drawing in the workshop of Benozzo Gozzoli (1420-1497), one of the most successful and prolific painters of the Florentine Quattrocento. Drawing is revealed as a way of gathering and disseminating visual motifs in Gozzoli's workshop, a means of developing pictorial and narrative composition, and a tool for training workshop assistants. Whilst Gozzoli's aptitude for portraiture is well known, his sinopia sketches reveal a much underrated talent for figure drawing.
