Interpretations

On the basis of the Teotihuacan iconographical depictions of the feathered serpent, archaeologist Karl Taube has argued that the feathered serpent was a symbol of fertility and of internal political structures - contrasting with the War Serpent symbolizing the outwards military expansion of the Teotihuacan empire. Historian Enrique Florescano - also analyzing Teotihuacan iconography - argues that the Feathered Serpent was part of a triad of agricultural deities:

The feathered serpent was furthermore connected to the planet Venus because of this planet's importance as a sign of the beginning of the rainy season. To both Teotihuacan and Maya cultures, Venus was in turn also symbolically connected with warfare.

While not usually feathered, classic Maya serpent iconography seems related to the belief in a sky-, Venus-, creator-, war- and fertility-related serpent deity. In an example from Yaxchilan, the Vision Serpent has the human face of the young maize-god, further suggesting a connection to fertility and vegetational renewal; the Maya Young Maize god was also connected to Venus.

In Xochicalco, depictions of the feathered serpent accompany the image of a seated, armed ruler and the hieroglyph for the day sign 9 Wind. The date 9 Wind is known to be associated with fertility, Venus and war among the Maya and frequently occurs in relation to Quetzalcoatl in other Mesoamerican cultures.

On the basis of the iconography of the feathered-serpent deity at sites such as Teotihuacan, Xochicalco, Chichén Itzá, Tula and Tenochtitlan combined with certain ethnohistorical sources, historian David Carrasco has argued that the preeminent function of the feathered-serpent deity throughout Mesoamerican history was as the patron deity of the urban center - a god of culture and civilization.
