OMETECUHTLI and his wife OMECIHUATL symbolize the duality and primordial forces of nature... and all that kind of thing. The entire universe is their temple, but most worshippers prefer somewhere a little more modest.
Their four sons HUITZILOPOCHTLI, QUETZALCOATL, TEZCATLIPOCA and XIPE-TOTEC were also pretty big in the creation department. Often depicted as a half-man and half-woman figure, or vice versa. Could be an instance of Holy Transvestitution.
