CASTELLO, GIOVANNI BATTISTA ?), Italian historical painter, architect and sculptor, was born near Bergamo in 15oo or perhaps 1509, and is hence termed I1 Bergamasco. He belongs, however, to the school of Genoa, but does not appear to have been related to the other two painters named Castello, also noticed here. He decorated the Nunziata di Portoria in Genoa, the saloon of the Lanzi palace at Gorlago, and the Pardo palace in Spain. His best-known works are the "Martyrdom of St. Sebastian" and the picture of "Christ as Judge of the World" on one of the vaultings of the Annunziata. In 1567 he was invited to Madrid by Philip II., and there he died, holding the office of architect of the royal palaces. The date of death (as of birth) is differently stated as 1569 or 1579.
