Angot Festival is annually performed on 28th day of September during the town Fiesta in honor of St. Michael the Archangel, the Patron Saint of Prosperidad.
Angot Festival is characterized by a ritual called “Bat-ad”. The ritual is usually performed by a Babaylan, a well-respected faith-healing old man in the village. Bat-ad is an offering of food to Angot or Ompo, the god of abundant harvest, which includes a plate of rice, a boiled egg, broiled mudfish, a white wine and a mama. After the ritual, all villagers join together for a merry-making. Angot means “a thanksgiving ritual for the abundant harvest”.
