this deity was one of the earliest known gods of Mesoamerica, the "old, old" god of fire; references to Xiuhtecuhtli are prominent in the Templo Mayor, even if he appears as a "minor god" in the Florentine Codex, according to Leonardo López Luján (referenced by Patrick Hajovsky); Hajovsky adds that "Xiuhtecuhtli conflates notions of turquoise as fire-heat (tonalli) and time, and as H. B. Nicholson attests, he was 'the archetype of all rulers." These attributes originated in the father of Tezcatlipoca, who was Huehueteotl-Xiuhtecuhtli, also attributed as the "progenitor of all the gods" according to Thelma Sullivan.
