According to Roman Catholic tradition, on December 9, 1531, Juan Diego (a recently converted Aztec indigenous peasant) had a vision of a young woman while he was on a hill in the Tepeyac desert near Mexico City. The lady asked him to build a church exactly on the spot where they were standing. He told the local Bishop Juan de Zumarraga who asked for proof in exchange.
