Funeral Monument to the Anti-Pope John XXIII (detail)

Portraiture was Donatello’s major personal contribution to a commission that he undertook c. 1424 jointly with Michelozzo (by then his business partner): the monumental tomb of Baldassarre Coscia, the Anti-Pope John XXIII (d. 1419). Donatello himself must have been responsible for the ennobled rendering of the fleshy, care-worn face and complex drapery of the effigy, which was cast, like the St Louis, in bronze and then gilded.
