 His works, highly dramatic, designed to be seen from multiple ponts of view, and spiraling upwards, had an immense impact on European sculpture.He continued to dominate Italian sculpture through his works on Roman fountains, the Baldequin of St. Peter and the tomb of Pope Alexander VII within St. Peter's Basilica, and his altar ensemble for the Church of Santa-Maria della Vittoria in Rome.He received his final fountain sculpture commission for the Fountain of the Elephant (1665–1667), followed by a series of angels for the Sant Angelo Bridge in Rome (1667–69).
