(b. 1536, Hoorn, d. 1578, Roma)
Netherlandish engraver who studied under Hieronymus Cock of Antwerp. About 1536 he went to Venice, where Titian employed him to execute the well-known copperplates of St Jerome in the Desert, the Magdalen, Prometheus, Diana and Actaeon, and Diana and Calisto. From Italy he wandered back to the Netherlands, but he returned to Venice soon after 1567, proceeding thence to Bologna and Rome, where he produced engravings from all the great masters of the time.
In Rome he founded the well known school in which the simple line of Marcantonio Raimondi was modified by a brilliant touch of the burin, afterwards imitated and perfected by Agostino Carracci in Italy and Nicolaes de Bruyn in the Netherlands.
In Italy, where he spent 12 years of his life, he was known as Cornelio Fiammingo.
