Kohunlich, Temple of the Masks

Masks of the sun god, Kinich Ahau, flank the stairway [Dec. 31, 1997]

"Although Kinich Ahau, or Ah Kinchil, the sun-faced one, has been considered a distinct figure, he seems clearly to have been the day aspect of Itzamna. As such, symbolizing the sun's life in its daily journey across the sky, and hence all life, this aspect of Itzamna was closely associated with Maya rulers. The rulers of several Maya centers appear to have assumed an identity with Kinich Ahau, either because they wanted to associate themselves with their powerful supernatural patron or because they wanted to foster the belief that they were manifestations of the sun god."
