SUN DOORWAY:

The Sun Doorway explores an apparent "dualism" between the keyhole shaped
doorway and pyramid ceremonial Structures. The keyhole door and the geometric
form of a spiral represents the helical curve or analemma formed by the suns
annual pathway. The sites at Uxmal, Mexico and Chaco Canyon, New Mexico have
similar forms. The Uxmal site (Governor's Palace) is of post-classic Maya (Toltec) origin.
The Toltec's were Uto-Aztecan speaking peoples, as were the Hopi's of Arizona.
