Ollin's patron is Xolotl, the twin of Quetzalcoatl, a dog headed god who guides the sun through the underworld each night and who, in the Legend of the Five Suns, journeys into Mictlan alongside his brother to recover the bones from which the present human race is fashioned, a deity whose whole mythic role concerns motion between states, night and day, death and life, matching the movement sign's theme directly. Its direction is east, the fourth instance of that direction after Cipactli, Coatl and Atl, standing at the recurring interval the four direction rotation follows across the full twenty signs.
Ollin is not a year bearer, sitting between Acatl at thirteen and Tecpatl at eighteen, outside the select spacing that defines the four signs able to open a solar year. Xolotl's patronage of Ollin as a day sign is a separate office from his role as trecena patron of Trecena 16, opening on Cozcacuauhtli the vulture, a considerably gentler sign than the movement sign's own dramatic reading, so the twin god's two calendrical posts span nearly the full range of the count's emotional register, from the vulture's patient old age to the movement sign's world ending resonance. Xolotl's own offering of blood alongside Quetzalcoatl's in the Legend of the Five Suns, the act that finally animates the ground bones into living people, ties his patronage of the movement sign to a myth in which motion itself, blood drawn and given, is the exact mechanism that makes something genuinely new begin.
