I did not realize he died at 37. There is so much of his stuff out there I thought he died in old age. At least he went out with a bang.
According to Vasari, Raphael's premature death on Good Friday (April 6, 1520), which was possibly his 37th birthday, was caused by a night of excessive sex with Luti, after which he fell into a fever and, not telling his doctors that this was its cause, was given the wrong cure, which killed him. Vasari also says that Raphael had also been born on a Good Friday, which in 1483 fell on March 28.
