Nearly every inquirer into the primitive superstitions of men has observed a close relationship, if not an absolute identity, in what are usually distinguished as Solar, Phallic, and Serpent Worship, yet the _rationalé_ of the connection has been rarely detected. They really are all forms of a single worship. "If (as it seems certain) they all three be identical," observes Mr. O'Brien, "where is the occasion for surprise at our meeting the sun, phallus, and serpent, the constituent symbols of each, occurring in combination, embossed upon the same table, and grouped upon the same architrave." We turn again to America. The principal God of the Aztecs, subordinate to the great Unity, was the impersonation of the active, creative energy, Tezcatlipoca or Tonacatlecoatl. He was also called Tonacatenctli. Like the Hindu Brahma, the Greek Phanes, and the Egyptian Phtha, he was the "Creator of heaven and earth," "the Great Father," "the God of Providence," who dwells in heaven, earth, and hades, and attends to the government of the world. To denote this unfailing power and eternal youth, his figure was that of a young man. His celestial emblem was Tonatiuh, the Sun. His companion or wife was Cihuacohuatl or Tonaeacihua, "the Great Mother" both of gods and men. The remaining gods and goddesses of the Aztec Pantheon resolve themselves into modified impersonations of these two powers. Thus, we have Ometuctli and Omecihuatl, the adorable god and goddess who preside over the celestial paradise, and which, though generally supposed to be distinct divinities, are, nevertheless, according to the Codex Vaticanus, but other names for the deities already designated. We have also Xiuhteuctli, "Master of the Year," "the God of Fire," the terrestrial symbol of the active principle, and Xochitli, "the Goddess of Earth and Corn;" Tlaloc and Cinteotl, or Chalchiuhcueije, "the god and goddess of the waters;" Mictlanteuctli and Mictlancihuatl, "the god and goddess of the dead;" the terrible Mexitli or Huitzlipochtli, corresponding to the Hindu Siva, in his character of destroyer, and his wife Teoyamiqui, whose image, like that of Kali, the consort of Siva, was decorated with the combined emblems of life and death.
