Chaac upon Temple
Chaac is featured again in the Puuc style. This face is part of the Temple of the Magician at Uxmal, a major Puuc city. The face of Chaac appears repeatedly down the sides of the stairway on the temple's western side. Because of the relatively dry nature of the northern Maya Lowlands in Yucatán, rain was a much higher demand than in the wetter highlands in the south. Therefore the price for rain was higher - during times of drought, more sacrifices to Chaac would be performed or the Maya would begin to pray to even more rain deities if necessary.
Isn't it weird how it bears a resemblance to an elephant or the Hindu God Vishnu?
