Xiuhtecuhtli

Xiuhtecuhtli (in the normalized classical Nahuatl spelling Xīuhtēuctli, literally translated as 'The Lord of Turquoise', 'The Lord of the Year' or 'The Lord of Fire') is the supreme deity of the Mexica of primordial fire, solar heat, the calendrical cycles of time, royal authority and the domestic hearth. Intrinsically fused with the archaic figure of Huehuetéotl ('The Old God', whose cult dates back to the pre-Classic horizons of Cuicuilco and the Classic horizons of Teotihuacan), Xiuhtecuhtli dwells at the very navel of the Earth (tlalticpac), vertically connecting the layers of the underworld and the thirteen heavens as the great cosmic axis of vital heat. He presided, as the supreme protagonist, over the solemn Ceremony of the New Fire (Toxhiuhmolpilia or 'The Binding of the Years'), a transcendent rite celebrated every fifty-two years on the summit of the Huixachtlan hill to renew the cycle of the sun and prevent the collapse of the universe under the celestial monsters, the Tzitzimime. In the divinatory calendar tonalpohualli, he governed as the first of the Nine Lords of the Night (Yoalteuctin) and ruled the ninth trecena (1-Coatl / 1-Serpent), bearing as his greatest insignia the flaming serpent Xiuhcóatl and the royal mosaic crown of turquoise worn by the Aztec monarchs.
