Agnolo di Cosimo, usually known as Agnolo Bronzino or simply as Bronzino (17 November 1503 – 23 November 1572) was an Italian Mannerist painter from Florence.
He was mainly a portraitist, but also painted many religious subjects, and a few allegorical subjects, which include what is probably his best-known work, Venus, Cupid, Folly and Time, c. 1544–45.
His sobriquet, Bronzino, may refer to his relatively dark skin or reddish hair.
