Giulio Romano was a proficient draftsman in chalks early in his career, but on the death of his master Raphael in 1520, he apparently abandoned chalk as a primary drawing medium. However a sheet in the British Museum, previously attributed to Raphael, seems to be a later chalk drawing by Giulio, in preparation for his frescoes in Palazzo Te, Mantua. The article argues the case for this attribution and considers what this sheet tells us about Giulio's later drawing practice more generally.
