(b. 1598, Bologna, d. 1654, Roma)
Italian Baroque sculptor and architect, born in Bologna. He studied painting, but later turned to sculpture. He executed such marble groups as St Philip Neri and the Angel for Santa Maria del Popolo in Rome and Beheading of St Paul for San Paolo in Bologna. He succeeded Bernini as papal court sculptor in 1644; he designed the Villa Doria-Pamphili and a large bronze statue of Pope Innocent X, now in the Palazzo dei Conservatori, both in Rome. In 1650 he completed the tomb of Pope Leo XI and a huge bas-relief for the altar of Pope Leo I in Saint Peter's Basilica, Rome, representing Leo's confrontation with the warrior Attila the Hun.
