El Tío (The Uncle), is believed in Cerro Rico, Potosí, Bolivia to be the "Lord of the Underworld". There are many statues of this devil-like spirit in the mines of Cerro Rico. El Tío is believed to rule over the mines, simultaneously offering protection and destruction. Some figures are in the shape of a goat. Miners bring offerings such as cigarettes, coca leaves, and alcohol for the statues and believe that if El Tío is not fed, he will take matters into his own hands. Villagers of Potosi ritually slaughter a llama and smear its blood on the entrance to the mines.
