Aztec god of rain and fertility,
Tlaloc was greatly feared among the Aztecs, who sacrificed humans to him to appease him. The Aztecs believed that Tlaloc was responsible for both floods and droughts, and that Tlaloc had been created by the other gods. Tlaloc was first married to
Xochiquetzal, a goddess of flowers, but then
Tezcatlipoca kidnapped her. Tlaloc later married the goddess
Matlolcueitl, "The Lady of the Green Skirts." Tlaloc is commonly depicted as a blue being with fangs. His underworld included those killed by lightning, drowning and disease. With
Chalciuhtlicue, he was the father of
Tecciztecatl. He had an older sister named
Huixtocihuatl. Children were drowned as sacrifices to him. He ruled over the third of the five worlds in Aztec belief.
The inhabitants of Teotihuacan also worshipped Tlaloc, though not violently. The Mayan god Chac is similar to Tlaloc, who was known from pre-Aztec times, worshipped by the Toltecs.
