The image is an illustration of a Mayan deity, El Agua y sus Cultos Religiosos, in a book. The illustration is in blue and red colors and is set against a white background. The deity is depicted in a traditional Mayan style, with intricate details and patterns. It is wearing a large headdress with a red and blue color scheme, and is holding a staff in one hand and a shield in the other.

In the center of the illustration, there is a large blue wave-like structure, which appears to be a representation of the Mayan civilization. The wave is made up of various symbols and figures, including a lion, a bird, and a fish. The figures are arranged in a way that they are interacting with each other, creating a sense of movement and energy. The text on the right side of the image is written in Spanish, which translates to "The Agua and the Cultos Religiousos" in English.
