 The Aztecs believed that Tlatlecuhtli's insatiable appetite had to be satisfied or the goddess would cease her nourishment of the earth and crops would fail.The Mexica believe Tlaltecuhtli to swallow the sun between her massive jaws at dusk, and regurgitate it the next morning at dawn.The fear that this cycle could be interrupted, like during solar eclipses, was often the cause of uneasiness and increased ritual sacrifice.
