Xolotl was the sinister god of monstrosities who wears the spirally-twisted wind jewel and the ear ornaments of Quetzalcoatl. His job was to protect the sun from the dangers of the underworld. As a double of Quetzalcoatl, he carries his conch-like ehecailacacozcatl or wind jewel. Xolotl accompanied Quetzalcoatl to Mictlan, the land of the dead, or the underworld, to retrieve the bones from those who inhabited the previous world (Nahui Atl) to create new life for the present world, Nahui Ollin, the sun of movement. In a sense, this re-creation of life is reenacted every night when Xolotl guides the sun through the underworld. In the tonalpohualli, Xolotl rules over day Ollin (movement) and over trecena 1-Cozcacuauhtli (vulture).
