Caselli was a pupil of Mazzuola, and lived in the 15th to 16th centuries. He earned his livelihood between 1489 and 1492 as a journeyman at Venice, where he painted, in 1495, an altar-piece now hanging in the Sacristy of Santa Maria della Salute. The Gallery of Parma contains a Virgin and Child, with SS. John the Baptist and Jerome probably painted by him before 1489. In 1496 he became a master at Parma, and painted in 1499 a Virgin and Child between SS. Hilarios and John the Baptist which is in the Sala del Consorzio in that city. The same year he executed The Eternal on a gold ground in a chapel of the cathedral, and the Adoration of the Magi in San Giovanni Evangelista. In 1507 he finished the monochrome of the Dead Christ in the cathedral.
