Tlahuizcalpantecuhtli
Tlahuizcalpantecuhtli (from Nahuatl: tlahuizcalpantecuhtli 'the lord at dawn'' tlahuizcalli, “dawn”; pan, “in”; tecuhtli, “lord” ') in Mexica mythology, dawn energy, the rosy colorful deity of the dawn. As his name indicates, Tlahuizcalpantecuhtli, the Lord of the Morning Star , is the personification of the morning star, the planet Venus, which makes him a manifestation of Quetzalcóatl. On some pages of the Borgia codex he appears as a skeleton archer. In certain thirteen it is said that he challenged the sun, but Tonatiuh killed him, turning him into Itztlacoliuhqui-Ixquimilli. In general, Tlahuizcalpantecuhtli was considered a dangerous energy. He is associated with Quetzalcoatl.
It is mentioned that he was adopted as a deity by the Toltecs, and that later some other cultures took him up again (such as the Mexicas), sometimes he is related to Quetzalcóatl "the feathered serpent" which symbolized the planet Venus. Then, it was known as Tlahuizcalpantecuhtli or morning star and also as the evening star it was known by the name of Xolotl, or his twin brother, as he was called in some civilizations. So we can interpret Tlahuizcalpan as "dawn star". Although of course, there could be discrepancies with other versions and someone else may say that it does not necessarily mean that, as the legend that can be found on the building says: TLAHUIZCALPAN (place where light is born). In the Mexica Calendar, Tlahuizcalpantecuhtli is the patron of the thirteen that begins on the day Ce Cóatl (1 Serpent) and ends with the day Mahtlactli Omei Ollin (13 Movement). In this he is paired with Xiuhtecuhtli, energy of fire.
