 Huehueteotl is frequently considered to overlap with, or be another aspect of, a central Mexican/Aztec deity associated with fire, Xiuhtecuhtli.In particular the Florentine Codex identifies Huehueteotl as an alternative epithet for Xiutecuhtli, and consequently that deity is sometimes referred to as Xiutecuhtli-Huehueteotl.However, Huehueteotl is characteristically depicted as an aged or even decrepit being, often with a beard, whereas Xiutecuhtli's appearance is much more youthful and vigorous, in line with his marked association with rulership and (youthful) warriors.
