Aztec Calendar Stone In 1790 workers repaving near the Cathedral in Mexico City discovered a stone eleven and one-half feet in diameter inscribed with the Aztec calendar. The stone have had bright polychrome colors and would have held sacrificed human hearts that the Aztecas believed were needed to feed the sun and keep civilization alive. This first study of the stone explained its 260-day divinatory cycle. The stone’s colossal size, elaborate patterning, and symbolic imagery have made it an unofficial emblem of Mexico.
