Centaurus's two brightest stars point observers to the Southern Cross in the Greek tradition. In the Andes, the same two stars are looking back at you: they are the eyes of Yacana, the llama.
Yacana is the largest of the Andean dark cloud constellations, read not from stars but from the black dust lanes that block the light of the Milky Way, a technique the Andes share with Aboriginal Australia and almost nowhere else, arrived at independently by both. Alpha and Beta Centauri, the same pair of stars the Greek tradition uses as pointers toward Crux, are read in this system as the llama's two eyes, with a smaller dark patch beside them read as her offspring.
The Huarochiri manuscript, the one substantial religious text written in Quechua during the colonial period, records that Yacana descends at midnight to drink from a spring, and that a person she descends upon will be fortunate; the same text warns that if she failed to drink, the world would flood. Her rising and setting through the year is tied directly to the herding calendar, one stage in an ordered sequence of animal figures, serpent, toad, tinamou, llama and fox, that functions as a working calendar rather than a set of separate resemblances.
Spanish colonial observers recorded the dark patches as native superstition without recognising a system was being shown to them, and the sequence was only properly documented in the twentieth century.
