From Iberia by James Michener pages 451-453(paperback edition):
To Alcala for their education had been sent three young men, Don Carlos, the son of King Felipe II; Don Juan the bastard brother of the king and therefor half uncle to Don Carlos; and Alexander Farnese, nephew of the King... on the night of April 19th, 1562, young Carlos slipped out of his room to visit the attractive daughter of a porter, and in creeping down the darkened stairs he failed to see that the fifth step was broken and pitched headlong forward, so that his forehead struck a closed door. He was found stretched out unconscious...
After word got out, a strange troupe appeared from a nearby community, a group of peasants who bore the cadaver of one Diego (1400-1463) a Franciscan who had died a century before but whose body had not been contaminated by the grave... The peasants explained the cadaver had already worked miracles in their community and they believed it could save Don Carlos...
When hope was almost gone, the century old cadaver of Fray Diego was placed in bed with Don Carlos while the Fransicans prayed, and in the morning Don Carlos awakened, with clear mind and said that in the night he had seen a Frair in Franciscan habit lying beside him and this had cured him....
In 1588 pope Sixtus announced that Fray Diego obtained Sainthood, and in his honor, a pueblo in the colony of California was some years later named after him.
That's right! San Diego was named after a miracle-working corpse!
