Which deity is known as the Mayan god of rain and thunder?

The Mayan god of rain and thunder is Chac. He is a significant deity within the Mayan pantheon, often depicted with various symbols associated with rain, fertility, and agricultural abundance. Chac is recognized for his role in providing rain essential for crops, which was vital for the agricultural societies of the ancient Maya. His portrayal often includes features such as a serpent-like nose and he is sometimes shown wielding a lightning axe. The reverence for Chac reflects the importance of rain in the Mesoamerican agricultural cycle, showcasing how deeply intertwined the Mayan religion was with their environment and sustenance practices.

In contrast, other deities listed have different cultural significances. Tlaloc is primarily associated with the Aztec culture rather than the Maya, although both cultures worshipped rain gods. Quetzalcoatl is a major god in the Aztec pantheon known for his associations with wind and learning, and Yumil Kaxob is a lesser-known Mayan god connected more to maize rather than directly to rain and thunder. Thus, Chac stands out as the correct answer in this context concerning the Mayan belief system.
