Informaciones Jurídicas de 1666 (English: The Proceedings of 1666) is a Spanish document that helped support the apparition of the Virgin Mary to Juan Diego Cuauhtlatoatzin at the hill of Tepeyac in 1531. The apparition is also known today as the iconic Virgin of Guadalupe. The Proceedings of 1666 consist of a series of investigations, record examinations, testimonies from artists, physicians, and Aztec historians, and oral accounts from elderly men and women who had knowledge and experience with Juan Diego and his contemporaries.
