Raphael was an Italian painter and architect during the High Renaissance period. He is admired for the clarity and ease of his compositions and for achieving the Neoplatonic ideal of human grandeur in his visual works. Along with Michelangelo and Leonardo da Vinci, Raphael is considered one of the great masters of the Renaissance period. He had an unusually large and productive workshop in Rome, where he created many frescoes for the Vatican Palace, including his most famous work The School of Athens. Raphael had three distinct phases and styles over his career: his early years in Umbria, absorbing Florentine artistic traditions, and his last successful period in Rome working for two Popes.
