The Missionary Image of Our Lady of Guadalupe

Mesoamerica, the New World, 1521: The capital city of the Aztec empire falls under the Spanish forces. Less than 20 years later, 9 million of the inhabitants of the land, who professed for centuries a polytheistic and human sacrificing religion, are converted to Christianity. What happened in those times that produced such an incredible and historically unprecedented conversion?

In 1531 a "Lady from Heaven" appeared to a poor Indian at Tepeyac, a hill northwest of Mexico City; she identified herself as the Mother of the True God, instructed him to have the bishop build a temple on the site and left an image of herself imprinted miraculously on his tilma, a poor quality cactus-cloth, which should have deteriorated in 20 years but shows no sign of decay 474 years later and still defies all scientific explanations of its origin.

It apparently even reflects in her eyes what was in front of her in 1531!
