Rafael

Raphael (a self portrait is at left) was a young rival (though admirer of) both Leonardo and Michelangelo. The latter distrusted Raphael and had the Sistine Chapel locked at night hoping to prevent the younger artist's efforts at "copying." Perhaps Raphael's most famous painting, "The School of Athens" (above left) reveals the Renaissance's use of perspective and light. It also shows the relationship between Raphael and his older contemporary and competitor, Michelangelo. Apparently the dark, brooding figure in the foreground of the painting is the sour (and dour) Michelangelo himself (The two artists were at work in the Vatican at the same time--Michelangelo in the Sistine Chapel and Raphael in the pope's library). Raphael also playfully included himself (in the dark beret) on the far right of the work. On the link below, make sure to click on Raphael's works for an enlarged image:
