Raphael
One of his most important papal commissions was the Raphael Cartoons (now in the Victoria and Albert Museum), a series of 10 cartoons, of which seven survive, for tapestries with scenes of the lives of Saint Paul and Saint Peter, for the Sistine Chapel. The cartoons were sent to Brussels to be woven in the workshop of Pier van Aelst. It is possible that Raphael saw the finished series before his death—they were probably completed in 1520. He also designed and painted the "Loggie" at the Vatican, a long thin gallery then open to a courtyard on one side, decorated with Roman-style grottesche. He produced a number of significant altarpieces, including "The Ecstasy of St. Cecilia" and the "Sistine Madonna". His last work, on which he was working up to his death, was a large "Transfiguration", which together with "Il Spasimo" shows the direction his art was taking in his final years—more proto-Baroque than Mannerist.
Timoteo Viti
The precocious Raphael, who was eleven at his father's death, continued to run his father's workshop with help from his family. It has often been speculated that Viti contributed to Raphael's training. In any case they remained friends, and Viti obtained or inherited the most important group of Raphael's studio drawings, which his descendents sold to Pierre Crozat in the 17th century. Drawings have often been disputed between the two artists in the past, and Viti has also been accused of forging some Raphael drawings (though it seems now accepted this was someone else).
