Co-creator of the Mixtec pantheon-tier, paired with Lady 1 Deer. The Apoala sacred-tree emergence is the foundational Mixtec cosmogonic event, depicted in the obverse of the Codex Vindobonensis (Yuta Tnoho) and corroborated by colonial-period Spanish ethnography (Reyes 1593, Burgoa 1674). The cleft tree at Yuta Tnoho — interpreted by Jansen & Pérez Jiménez (2007) as a metaphor for genealogical bifurcation — engenders the second-generation Mixtec pantheon (Lord 9 Wind "Quetzalcoatl," Lord 7 Flower, Lord 4 Snake, etc.) who in turn engender the founder-dynasties of the Mixteca-Alta polities. The Apoala valley itself in northern Oaxaca remains an active site of indigenous-traditional veneration. The Iya + calendar-day-name onomastic pattern (here Iya Nacuaa = "Lord 1 Deer") is the foundational Mixtec naming-convention, structurally parallel to but iconographically and linguistically distinct from Aztec/Mexica naming.
