San Gervasio is an archaeological site of the pre-Columbian Maya civilization, located in the northern third of the island of Cozumel off the northeastern coast of the Yucatán Peninsula, in what is now the Mexican state of Quintana Roo. San Gervasio's pre-Hispanic name was Tantun Cuzamil, Mayan for Flat Rock in the place of the Swallows. The ruins were once a hub of worship of the goddess Ix Chel, deity of the moon, childbirth, fertility, medicine, and weaving. Although some sources state the meaning of her name means "She of the Rainbow," derived from the similar-sounding Mayan words Ix and Cheel, her name was Ix Chel; Ix, meaning female, and Ch’el, meaning white or pale face, a name befitting a moon goddess. She is also identified in the Madrid Codex as "the White Lady." Archaeologists identify her as the Classic Period Goddess I.
Pre-Columbian Maya women would try to travel to San Gervasio and make offerings at least once in their lives. In 1560, the Spanish historian, Diego Lopez de Cogolludo, wrote: "The pilgrims arrive at Cozumel for the fulfillment of their vows to offer their sacrifices, to ask help for their needs, and for the mistaken adoration of their false gods." The bishop of Yucatán, Diego de Landa, wrote in 1549 that the Maya "held Cozumel in the same veneration as we have for pilgrimages to Jerusalem and Rome, and so they used to go to visit and offer presents there, as we do to holy places; and if they did not go themselves, they always sent their offerings."
