Raphael Rooms
Between 1509 and 1511, Raphael also completed another work on the wall opposite the "Disputa". This third painting, entitled "The School of Athens", represents the degrees of knowledge or the truth acquired through reason. The fresco's position as well as the philosophers' walk in direction of the Holy Sacrament on the opposite wall suggested the interpretation of the whole room as the movement from the classical philosophy to the true religion and from the pre-Christian world to Christianity. It was meant to reside over the philosophical section of Pope Julius II's library. It is perhaps Raphael's most famous fresco.
Timoteo Viti
In 1503 Viti was painting banners for Cesare Borgia, who had expelled Duke Guidobaldo da Montefeltro as lord of the city. Guidobaldo regained Urbino in 1504 and Viti, along with Girolamo Genga, was commissioned by Bishop Arrivabene to decorate the chapel of S Martino in the cathedral. He continued to work successfully in the Marches for the rest of the decade, and as far south as Siena, where he and Genga collaborated on paintings in the Palazzo Petrucci in about 1508. 
Around 1514, Viti formed part of the large team assembled by Raphael and worked on the frescoes Raphael designed in the Chigi Chapel in Santa Maria della Pace in Rome. It has been suggested that he is depicted (as the Ancient Greek painter Protogenes) in "The School of Athens", Raphael's most famous work, standing next to Raphael's self-portrait, although Vasari does not mention this identification.
