Polyptych by Gonzalo Pérez
The Altarpiece of Saints Ursula, Martin and Anthony is a reredo by the Spanish late Gothic painter Gonzalo Pérez, dating to 1420 and housed in the Museu de Belles Arts of Valencia, Spain.
Painted in the International Gothic style (with influences, such as in St. Martin's rich garments, by the Italian Gentile da Fabriano), it is one of the artist's few known works, painted for the Portaceli Monastery.
