Tlahuizcalpantecuhtli

Tlahuizcalpantecuhtli is an Aztec deity representing the planet Venus and an apparition of Quetzalcoatl, the feathered serpent. Tlahuizcalpantecuhtli means "Lord of the House of Dawn." He was the lord of the twelfth hour of the day.

The Aztec rituals were enacted when the Sun, (Huitzilopochtli) was in a particular position in the sky in relation to the position of the planet Venus, identified with Tlahuizcalpantecuhtli, and that of the Pleiades, known by the Aztecs as Tianquiztli. Even today we can admire at Tula, an important archaeological site in Mexico, the temple of Tlahuizcalpantecuhtli, dedicated to the planet Venus.
