Who was the Mayan sun god?

Kinich Ahau was the Maya sun god, known in Classic Maya studies as God G.

The name Kinich Ahau is associated especially with Yucatec and Lacandon Maya traditions, while scholars use “God G” for the sun deity represented in Classic-period inscriptions and art. The name is commonly interpreted as relating to the sun or “sun-eyed” lord. Artists often portrayed the deity as a mature or elderly man with large square eyes, an aquiline nose, filed upper teeth, and a solar sign incorporated into his features.

Kinich Ahau was more than a representation of daylight. Maya rulers could be symbolically identified with the sun god, linking royal authority with celestial power and ideas of rebirth. In Maya cosmology, the sun’s journey continued after sunset: solar imagery connected the deity with an underworld passage before sunrise in the east. He was also associated with the day-unit k’in and with the month Yaxk’in.

The other choices belong to different traditions: Ra is Egyptian, Surya is Hindu, and Inti is Inca. Kinich Ahau should not be confused with Ah K’in, a Yucatec term for a daykeeper or calendar priest. In some accounts, the sun deity was also treated as an aspect of Itzamna.
