Chaac

Chaac (Chahk) is the rain and storm god of the Maya, one of the most important and most frequently depicted deities of the whole tradition, unsurprisingly, in a farming society dependent on seasonal rain for its maize. He is recognizable by a long, curling, pendulous nose or snout, reptilian features, and a lightning-axe or serpent that he wields to strike the clouds and loose the rain; images of him crowd Maya ceramics, codices and the facades of buildings, where masks identified with the rain-god (long called Chac masks) are repeated across whole walls, as at the Puuc sites of Yucatan. He is often reckoned as four, one for each of the world-directions with its associated colour.

The clearest single monument to Chaac's visual importance is the Codz Poop, the Palace of the Masks, at the Puuc site of Kabah in Yucatan, whose entire main facade is covered with several hundred individually carved stone Chaac masks stacked in repeating vertical rows, an unmatched concentration of the rain-god's image on a single building anywhere in the Maya world. Related but less extreme repetitions of the long-nosed mask appear across other Puuc-style buildings, including the Nunnery Quadrangle at Uxmal, showing how central Chaac's invocation was to the architectural decoration of this particular Late Classic regional style, more than for almost any other Maya deity.

Chaac is not only an archaeological figure. Among Yucatec Maya communities today the rain-deities live on as the chaacs or chaakob, and the agricultural ch'a chaak ceremony, a rain-petitioning rite performed by a h'men (ritual specialist), with offerings and prayers to call the rain for the maize, continues to be held in the present in parts of Yucatan, often blended with Catholic elements. Contemporary Maya religion is a living tradition in its own right, not merely a survival of the ancient one, and its rain-rituals are best understood on their own terms as much as through their evident continuity with the Classic-period cult of the rain-god.

Ethnographers and anthropologists have documented the ch'a chaak rain ceremony in Yucatec communities since at least the early twentieth century, and accounts show real variation from town to town in its details, offerings and timing, reflecting the same local diversity long documented across other living indigenous American rain-petitioning traditions rather than a single fixed rite. Community elders and h'menob generally treat the specifics of the ceremony as belonging properly to their own local practice, and outside descriptions accordingly tend to stay at the level of general structure, the invocation of the four directional rain-bringers, offerings of food and drink, prayer, rather than reproducing the ceremony's particular words.
