Hinilawod is an epic poem orally transmitted from early inhabitants of a place called Sulod in central Panay, Philippines. The term "Hinilawod" generally translates to "Tales From The Mouth of The Halawod River". The epic must have been commonly known to the Visayans of Panay before the conquest, since its main protagonists, like Labaw Donggon, were noted in the accounts of the Islanders' beliefs and recorded by early Spanish colonizers. One of these Westerners' accounts says that the adventures of this ancient hero of Panay were recalled during weddings and in songs. It was noted that there were still native Mundos of Dingle, Iloilo who worshipped Labaw Donggon even during the last years of the Spanish rule in the Philippines. These worshippers would stealthily enter a certain cave in Dingle in the evening of a certain day of the year, in order to render homage and to offer chickens, doves, rice, bananas, and pigs to the ancient Visayan god.
