The mural below is of Quetzalcoatl, the second of two by José Clemente Orozco in the series An Epic of American Civilization, painted from 1932-34, in the Baker Library at Dartmouth College in Hanover, New Hampshire. The first mural shows The Coming of Quetzalcoatl; the second, most of which is shown here, is known as The Departure of Quetzalcoatl.
Does this mural in any way imply that Orozco is criticizing the Aztecs for driving off their god Quetzalcoatl, for falling away from his utopian teachings of love and wisdom? It would seem so, all the worse because it allowed Cortés to find a way in, and to maintain the tradition of bloody sacrifice they had embraced in Quetzalcoatl's absence. More Orozco murals here.
The most important Aztec center of worship for Quetzalcoatl was at Cholula, near Puebla, but only a section of a staircase on one side of the Great Pyramid of Cholula (Tlachihualtepetl) has been restored to its former state - below.
If viewed from another side, what you see on top of the now buried pyramid is, no surprise here...
