Manzu, Giacomo (1908-91), Italian sculptor. His figurative works, with surfaces ranging from rough and expressive to smooth and simplified, have an underlying grace and proportion that show the influence of classical principles. After producing several series devoted to female figures and to ecclesiastical officials, he carved the massive reliefs for the fifth ceremonial bronze door (commissioned 1949, finished 1962, dedicated 1964) of Saint Peter's Basilica in Rome, and the portal sculptures for the Italian Government Travel Office in New York City's Rockefeller Center.
