De triomf van Galatea (detail) - Rafaël

Raphael died on his birthday, at thirty-seven. Good Friday, 6 April 1520. He had been working himself to exhaustion on simultaneous commissions for the Pope, the Vatican, and half the Roman aristocracy. The fever that killed him may have been made worse by the bloodletting his doctors prescribed. He was the most famous artist in Europe. His funeral procession passed through streets lined with mourners and his unfinished painting, The Transfiguration, was placed at the head of his bier.

He was born in Urbino, the son of a painter. His father died when he was eleven, and by his teens he was already working in the studio of Perugino, whose smooth, symmetrical compositions gave Raphael his starting point. He surpassed Perugino quickly. He studied Leonardo's sfumato and Michelangelo's anatomical intensity and absorbed both without losing his own clarity. The Madonnas from his Florentine period (the Madonna of the Goldfinch, the Sistine Madonna) have a serene perfection that has been imitated for five hundred years and never matched.

Pope Julius II summoned him to Rome in 1508, the same year he commissioned Michelangelo for the Sistine ceiling. Raphael painted the Stanze della Segnatura: four rooms in the Vatican whose frescoes include The School of Athens, the single most famous image of classical philosophy. Plato and Aristotle walk through an ideal architecture surrounded by every major thinker of the ancient world. Raphael painted Michelangelo into the scene as Heraclitus, brooding alone on the steps. Michelangelo was furious.

He ran a large workshop that produced portraits, altarpieces, tapestry designs, and architectural plans. He was appointed architect of St Peter's Basilica. He was charming, diplomatic, and universally liked, which made Michelangelo dislike him even more.
