 A jade statue of a skeletal Xolotl carrying a solar disc bearing an image of the Sun on his back (called "the Night Traveler") succinctly portrays Xolotl's role in assisting the Sun through the process of death, gestation, and rebirth.Xolotl's association with ollin motion-change suggests proper completions and gestations must instantiate ollin motion-change.Ollin-shaped decomposition and integration (i.e., death) promote ollin-shaped composition and integration (i.e., rebirth and renewal).
