Italian, 1535-1612 .Italian painter. The leading altar painter in Italy in the second half of the 16th century, he enjoyed a greater popularity and exerted a more profound influence on the art of his time than any of his contemporaries. His patrons included the Pope, Emperor, King of Spain and Grand Duke of Tuscany, and among his admirers were Lodovico Cigoli, Annibale Carracci, Rubens and Guido Reni. However, his work did not begin to receive the acclaim accorded that of Tintoretto or El Greco until the mid-20th century. Several factors have obscured his importance, notably the relative inaccessibility and scarcity of his painted works, most of which were done on commission for specific locations in remote parts of Italy (where they have remained), and the type of painting he produced, which was almost exclusively devoted to religious subjects. He executed very few easel paintings. No autograph example of his painted work has ever left Europe, the portrait of Quintilia Fischieri (c. 1600; Washington, DC, N.G.A.) and pair of portraits of Federigo Ubaldo, Prince of Urbino
