This letter presents a sweeping, mythic biography of Quetzalcoatl, the Feathered Serpent, whom Hall interprets not as a single historical figure but as a lineage of Initiate‑Kings stretching back to remote antiquity—much like Hermes, Zoroaster, or the several Orphic sages. The letter opens by surveying the many names attributed to him across Mesoamerica—Quetzalcoatl, Kukul‑Kan, Ehecatl, Yokcuat, Tohil, Nanihehecatl—each expressing a facet of his cosmic identity as wind‑spirit, serpent‑power, and divine teacher. Hall argues that the earliest Quetzalcoatl was likely an Atlantean priest‑king whose mysteries were carried to the Americas by survivors of the cataclysm, later embodied by successive human incarnations who assumed his mask and title. The narrative then unfolds the legendary life of the god‑man: his immaculate conception through the breath of Ometecutli, his miraculous birth accompanied by celestial omens, his arrival from Tlapallan on a raft of serpents, and his reign among the Toltecs, where he restored paradise through magic, sacrifice, and spiritual reform.

The second half of the letter explores the esoteric symbolism embedded in Quetzalcoatl’s myth—his fasting, temptation, sacrificial blood‑offering, magical wand, and solar identity as Lord of the Morning Star. Hall highlights striking parallels with other Mystery traditions: crucifixion motifs in the Vatican Codex, resurrection imagery, the “bread‑body” ritual, and the demi‑god pattern of a divine son mediating between heaven and earth. The narrative culminates in the dramatic fall of the Toltec Golden Age through the sorcery of Tezcatlipoca, Quetzalcoatl’s departure toward the east, and multiple accounts of his death or ascension—vanishing over the sea, rising in a divine flame, or becoming the Morning Star. Hall concludes by examining fragments of Nahua cosmology: the five world‑ages, the 52‑year “binding of years,” and the profound metaphysical sophistication of ancient Mexican priest‑philosophers. Through these layers, Quetzalcoatl emerges as a universal archetype of the dying‑and‑rising Initiate, a bearer of wisdom whose return signals the dawn of a new spiritual epoch.
