Agnolo di Cosimo, called Bronzino. Florentine School. Born 1503; died 1572. After a brief training under Raffaellino del Garbo, he worked, through the 1520s, as assistant to Pontormo, by whom his style was strongly influenced. By the mid-1530s his own individuality had become manifest, notably in a harder, more sculpturesque modeling of forms and a much more impersonal expression.
