Ek Chuah, the 'Black Scorpion,' is the Yucatec Maya patron of long-distance merchants, of the cacao that served as currency, and of travelers on the road. Landa describes him as a god painted black, with a long drooping lip and, in the codices, a scorpion tail and a merchant's pack borne on a tumpline. Traders on the trail built a small cairn of three stones each night, laid copal upon it, and burned incense to him for protection, while cacao planters honored him alongside Chaac and the Bacab Hobnil in a festival of the month Muan. He corresponds to God M and, in his darker martial aspect, is also linked to war.
