Ometecuhtli

In Aztec mythology, Ometecuhtli ("two-lord"; also Ometeoltloque, Ometecutli, Tloque Nahuaque, Citlatonac) was a god of fire, a creator deity and one of the highest gods in the pantheon, though he had no cult and was not actively worshipped. He, along with his wife, Omecihuatl, was the source of life on Earth; the pair were aspects of Ometeotl.
