      Sixty-eight original peoples.

      Mexico is home to 68 original peoples, each with its own language and way of naming the world, and to Afro-Mexican communities. Mesoamerican cosmology shares common threads: thirteen heavens and nine levels of Mictlan, the land of the dead; time counted in the 260-day tonalpohualli and the 365-day xiuhpohualli; and a world renewed every 52 years.

      Cosmovision

      The pyramid, a plan of the world

      The sacred mountain

      The god lives in the upper layers of the universe, so the temple must be raised toward him (Gendrop, 1976, p. 40). The pyramid stands between the thirteen heavens and the nine underworlds, and Tenochtitlan, with its twin temple of Huitzilopochtli and Tlaloc in the middle of a lake and causeways to the four directions, drew the whole universe on the ground.

      The plan of the world

      The plan of the world, Codex Borgia 72.

      Each of the twenty days of the count belongs to one of the four directions and carries its symbol; the centre is balance. Plate 72 of the Codex Borgia places five day-signs in each direction. Today’s sign shines in its place.
