Matigsalug are the original inhabitants of the Salug River (now called the Davao River). Thus, their name comes from the words matig, meaning “from,” and salug, meaning “river”.
They maintain that spirits live in water, land, trees, and rocks. Tragedies like illnesses, drought and death are caused by angry spirits. Events like planting crops and revenge-taking (called “pangayaw”) are preceded by rituals. Life is preoccupied with appeasing the spirits by offering sacrifices. Eggs, rice, corn, coins bracelets, anklets and betel nuts are placed on an altar, and the Datu, while calling on the spirits, slits the throat of a chicken and offers the blood.
