He was first noticed by the Genoese merchant of artworks, Pellegrino Peri, who was living in Rome. Peri introduced him to Gianlorenzo Bernini, who promoted him. He found patrons among the Genoese Giovanni Paolo Oliva, a prominent Jesuit. In 1662, he was accepted into the Roman artists' guild, the Accademia di San Luca (Academy of Saint Luke), where he was to later hold several offices. The next year, he received his first public commission for an altarpiece, in the church of San Rocco, Rome. He received many private commissions for mythological and religious works.
