Tianquiztli
The Pleiades were known to the Aztecs as Tianquiztli which means "marketplace." The Aztecs were great observers of the Sun, moon, and planets.Time was measured according to the movement of the stars and the Sun. Their calendar was
based on cycles of fifty-two years. They watched the Pleiades carefully move in
the sky to ensure that the world would not end.
