Juan Diego Cuauhtlatoatzin was a 16th-century Nahua peasant and visionary from Mexico. He is primarily remembered for his reported encounters with Our Lady of Guadalupe at Tepeyac Hill in December 1531. According to tradition, these apparitions led to the miraculous impression of the Virgin's image upon his cloak, known as a tilma. As the first indigenous person from the Americas to be canonized by the Catholic Church, he remains a central figure in Mexican spirituality and a symbol of indigenous faith.
