Juan Cornago | Patres nostri peccaverunt (15th century) Juan Cornago (or Johannes Cornago) is the earliest Spanish composer with a large number of surviving works. Almost nothing is known of Cornago's origins. He may be the Juan Carnago of Calahorra, La Rioja, Spain, who solicited Pope Martin V for prebends in various parishes between 1420 and 1429. It is certain that he is the Cornago, a Franciscan, who graduated from the University of Paris in 1449. Then from 1453 he was in Naples serving in the royal chapel of Alfonso V of Aragon, where Pope Calixtus III issued him a bull in order to officially recognize him as Alfonso's chaplain.
