The Madonna and Child Enthroned with Saints Francis of Assisi, Jerome, Catherine of Alexandria and Anthony of Padua

This painting is the only securely identified work of Francesco di Gabriele da Viterbo, who was active at the beginning of the 15th Century. Faldi (op. cit., pp. 22-3) claimed that he was the grandson of the prolific Francesco d'Antonio Zacchi (active by 1430-died before 1476) and the son of Francesco di Gabriele. A number of elaborate panels and polyptychs by Zacchi have survived, mainly in and around Viterbo, while rather fewer works attributable to Francesco di Gabriele still exist. A pair of wings from an altarpiece representing Saints Victor and Andrew (Chiesa Collegiata di Sant' Andrea, Vallerano) can, however, be dated to 1473 and a fresco of the Pietà with Saints Francis and Jerome (formerly San Bernardino, Viterbo) is signed and dated 1483.

Based solely on the present painting, it would seem that Francesco betrays various artistic influences from Tuscany, Umbria and Rome. The Christ Child is very close to that found in an altarpiece by Panciatico di Antonello da Calvi in the Museo Civico, Viterbo.
