Giovanni Antonio Boltraffio (or Beltraffio) (1466 or 1467[1] – 1516) was an Italian painter of the High Renaissance from Lombardy, who worked in the studio of Leonardo da Vinci.[2] Boltraffio and Bernardino Luini are the strongest artistic personalities to emerge from Leonardo's studio. According to Giorgio Vasari, he was of an aristocratic family and was born in Milan.
