In Aztec religion, Huixtocihuatl[pronunciation?] (or Uixtochihuatl, Uixtociuatl) was a fertility goddess who presided over salt and salt water. The Aztecs considered her to be the older sister of the rain gods, including Tlaloc.[1] Much of the information known about Huixtocihuatl and how the Aztecs celebrated her comes from Bernardino de Sahagún's manuscripts. His Florentine Codex explains how Huixtocihuatl became the salt god.[2] It records that Huixtocihuatl angered her younger brothers by mocking them, so they banished her to the salt beds. It was there where she discovered salt and how it was created.[2] As described in the second book of the Florentine Codex, during Tecuilhuitontli, the seventh month of the Aztec calendar, there was a festival in honor of Huixtocihuatl. The festival culminated with the sacrifice of Huixtocihuatl's ixiptla, the embodiment of the deity in human form.[2]
