Quetzalcoatl rises above the pyramids of Teotihuacan, temples of his worship. To the right of the sleeping figures, in the shelter of an abstract suggestion of a Toltec house, is a conversing group symbolic of the beginnings of understanding and cooperation, qualities which Orozco considers basic in any advanced civilization. The interesting elements of composition developed in this panel form an important part of the integrated composition of this wall. The color key is heightened with reds and blues in the garish parade of the gods. Deep, rich browns contrast with cool grays in the lower foreground.
Art is represented in the figure of the sculptor at work on the dark block of stone.
The amazing carvings of the Toltecs and Mayas are perhaps the most notable achievements of pre-Columbian art. Science is suggested through the contemplative figure, whose closed eyes imply an inner activity of the mind. His eloquently upraised arm indicates, perhaps, intellectual activity as an advance into the unknown. The grill of a ventilator appears in this panel. When asked if it would be necessary to have this feature removed, Orozco, who was an architect before he was a painter, was emphatic in saying no.
