Xiuhtecutli, also known as
Huehueteotl-
Xiuhtecuhtli, is the oldest of the
Aztec or
Mexica gods and his home was thought to be the center of the
Universe. His
glyph shows an old, toothless, hunchbacked man, his face being either yellow or red, carrying a large
brazier on his back. His great age symbolizes his experience and wisdom. He is the god of light and fire, the god of life in death, light in darkness, warmth in cold, opposites and paradoxes. His wife was
Chalchiuhtlicue, godess of water and vegetation, but she is also represented as the wife of
Tlaloc.
