A young man [from 'The School of Athens']

A photograph of a drawing by Carlo Maratti now in the Royal Library at Windsor Castle (RCIN 904258). The drawing reproduces the head and shoulders of the young man resting his head on his right arm, standing to the left of Socrates at the top of the stairs in Raphael's 'School of Athens', painted in c.1509-10 in the Stanza della Segnatura in the Vatican.
