Juan Diego Cuauhtlatoatzin, also known simply as Juan Diego (Spanish pronunciation: [ˌxwanˈdjeɣo]; 1474–1548), was a Nahua peasant and Marian visionary. He is said to have been granted apparitions of Our Lady of Guadalupe on four occasions in December 1531: three at the hill of Tepeyac and a fourth before don Juan de Zumárraga, then the first bishop of Mexico. https://en.wikipedia.org/wiki/Juan_Diego
