This sheet is connected with the painting of The Youthful Saint John the Baptist in the tribuna of the Uffizi. Recorded by Vasari as having been executed by Raphael for Pompeo Colonna, probably on the occasion of his appointment as a cardinal in 1517, it is now generally regarded as a work by Giulio Romano after an invention by his master. A badly damaged drawing in red chalk heightened with white in the Uffizi has recently been put forward as a preparatory drawing by Raphael for the picture. Like it, the present drawing cannot simply be a copy after the picture, because the Baptist is shown nude and there are other minor differences. The present drawing might, however, be a copy after a lost preliminary study. The penwork suggests neither Raphael nor Giulio, but rather their collaborator Giovanni Francesco Penni, whose role in the workshop appears to have involved making highly finished pen drawings of this type. A comparable pen drawing Jonah is at Windsor, A. E. Popham and J. Wilde, The Italian Drawings of the XV and XVI Centuries in the Collection of His Majesty the King at Windsor Castle, London, 1949, no.811, fig. 160
