As an architect and city planner, he designed secular buildings, churches, chapels, and public squares, as well as massive works combining both architecture and sculpture, especially elaborate public fountains and funerary monuments and a whole series of temporary structures (in stucco and wood) for funerals and festivals. His broad technical versatility, boundless compositional inventiveness and sheer skill in manipulating marble ensured that he would be considered a worthy successor of Michelangelo, far outshining other sculptors of his generation. His talent extended beyond the confines of sculpture to a consideration of the setting in which it would be situated; his ability to synthesize sculpture, painting, and architecture into a coherent conceptual and visual whole has been termed by the late art historian Irving Lavin the "unity of the visual arts".
