Drawing by Bronzino

Agnolo di Cosimo (November 17, 1503 – November 23, 1572), usually known as Il Bronzino, or Agnolo Bronzino (mistaken attempts also have been made in the past to assert his name was Agnolo Tori and even Angelo (Agnolo) Allori), was an Italian Mannerist painter from Florence. His sobriquet, Bronzino, in all probability refers to his relatively dark skin.
