Giampietrino, probably Giovanni Pietro Rizzoli (active 1495–1549),[1] was a north Italian painter of the Lombard school and Leonardo's circle, succinctly characterized by S. J. Freedberg as an "exploiter of Leonardo's repertory."[2]
^Though Andrea Bayer says "rather securely identified" (Bayer, "North of the Apennines: Sixteenth-Century Italian Painting in Lombardy and Emilia-Romagna" The Metropolitan Museum of Art Bulletin, New Series, 60.4 [Spring, 2003], p. 19), Sydney J. Freedberg says "It is uncertain whether this painter is to be identified with Gian Pietro Rizzi or Giovanni di Pietro of Como." (Freedberg, Painting in Italy 1500-1600 3rd ed. 1993:383, note 25).
