Сан-Сильвестро-ин-Капите
Most of his fresco work was in Rome, though he worked for a decade in Loreto (1605–1615), where he decorated the New Sacristy. In Rome he decorated the cupola of the church of Santa Maria di Loreto and of San Silvestro in Capite. He helped decorate "Santa Maria in Vallicella" for the Oratory of San Filippo Neri. He also painted for the Oratory of Santissimo Crocifisso, the "Baptism of Constantine" and "St. Simon" in the transept of San Giovanni in Laterano, and designed the mosaics in the "Cappella Clementina" in the St. Peter's Basilica. One of his pupils from Siena was Alessandro Casolano, and his son Ilario Casolano.
