Mixtec wind-and-air deity, plumed-serpent figure, identified with but iconographically and linguistically distinct from the Aztec/Mexica Quetzalcoatl. The foundational descent-from-heaven narrative — Lord 9 Wind descending on a knotted cord from the celestial realm to the Mixteca-Alta to establish cult-centers and instruct humanity in agriculture, ritual, and codex-painting — is the cosmogonic charter for the Tilantongo and Achiutla polities and the most-narratively-elaborated event in the Codex Vindobonensis. His parents Lord 1 Deer and Lady 1 Deer place him at the deity-deity tier with math-confirmed deity classification (f=1.0). His subsequent lifting-of-the-sky-and-separation-of-waters action establishes the cosmographic framework within which the dynastic history of the Mixteca-Alta proceeds. The Achiutla green-jade-stone idol, described by Burgoa (1674) as the most-important pre-Conquest cult image of the Mixteca, was destroyed by Spanish friars in the 1530s but is iconographically attributable to Lord 9 Wind via the conch-pectoral and wind-mask features.
