Codex Dresdensis, p. 74.
This is the only page in the manuscript that contains a single picture. Under the glyphs, the image depicts floods of water downpouring from the mouth of a crocodile-headed celestial dragon. The name of the dragon is Itzam.
An old goddess with claws pours more water out of a jar. She is the red goddess of weaving (O), Ix-Chel. Her headdress is a snake.
At the bottom is a god painted black, holding two darts. He is hard to identify, but possibly he is God L, whose headdress is a bird.
