The Doors of Oerth
The worship of Quetzalcoatl sometimes included animal sacrifices, and in colonial traditions Quetzalcoatl was said to oppose human sacrifice.
The last known Olman ruler of Tula was named Quetzalcoatl; there is some speculation as to his identity and baring as to whether he was truly a god, a human spell caster of immense power or something else.
It is believed that the Olman had a dualistic belief system. In some versions, Quetzalcoatl’s opposite was Tezcatlipoca, who, in one legend, sent Quetzalcoatl into exile. Alternatively, he left willingly on a raft of snakes, promising to return. The last Olman king however is known to have been somehow duped by the wizard Orobus into giving up his power.
The Olman revere Quetzalcoatl as a symbol of dying and resurrection and a as the creator and patron of humanity as a whole. As Olman culture progressed, they made twin gods of Tezcatlipoca and Quetzalcoatl, opposite and equal, representative accordingly of day and night; Quetzalcoatl was also called White Tezcatlipoca, to contrast him to the black Tezcatlipoca. Together, they created the world; Tezcatlipoca lost his foot in that process.
In addition to the dualistic nature the pair represented Quetzalcoatl was also part of a cyclical religion based on seasonal observances. In this progression where as Xipe Totec is the first sun, dawn or spring, Huitzilopitchli is the second sun, noon or summer, Quetzalcoatl is the fourth sun, the blue sun of autumn or dusk and Tezcatlipoca is the fourth sun, the black sun of night, or winter.
