Agony in the Garden
Piò mainly used stucco and colored terracotta, working in the Emilian Rococo style. He used these materials due to the scarcity of stone and marble, but was able to closely imitate stone carving. His works were mostly of religious, allegorical or mythological subjects. His more notable works include "Fortitude and Prudence" (Bologna, Gozzadini palace), "Agony in the Garden" (parish church of San Giovanni in Persiceto) and the funeral memorial of General Marsili (1733, San Domenico, Bologna).
