Raphael's "School of Athens" fresco (1510-11) is a notable symbolic tribute to philosophy that parallels Raphael's similar frescoes in the same room that delineate poetry, law, and theology. The central figures represent Plato and Aristotle. The figure in the forefront is Michelangelo, with his left hand against his head.
