Agnolo di Cosimo (1503-1572), usually known as Bronzino or Agnolo Bronzino, was an Italian Mannerist painter from Florence.
His sobriquet, Bronzino, may refer to his relatively dark skin or reddish hair.
He lived all his life in Florence, and from his late 30s was kept busy as the court painter of Cosimo I de' Medici, Grand Duke of Tuscany.
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, now in London.
