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".
Hinilawod is a 29,000-verse epic that takes about three days to chant in its original form, making it one of the longest epics known, alongside that of Tibet's Epic of King Gesar. Hinilawod is one of the many pieces of oral literature passed from one generation to the next, changed and morphed by the chanter to one degree or another as he told it to his audience. The Hinilawod is not just a literary piece but also a source of information about culture, religion and rituals of the ancient people of Sulod; showing us that ancient Filipinos believed in the "sacred," in the importance of family honour and in personal courage and dignity.
Hinilawod was first discovered "by accident" in 1955, when Filipino anthropologist F. Landa Jocano became interested in native folklore. He travelled the hinterlands of his home island of Panay with two colleagues collecting folk songs, stories, and riddles. It was during one of those trips to the upland barrios of Lambunao, Maasin, Janiuay, and Calinog in Iloilo that his attention was called to a long and popular tale called Hinilawod. Portions of the story were sung to him and his colleague by an old man called Ulang Udig.
Returning the following year with a radio technician from Central Philippine University, he then recorded a portion of the story on tape in 1956. However, when he returned, in 1957 to make a recording of the complete story, Ulang Udig refused to cooperate. Weeks later, he was introduced to a mountain singer named Hugan-an, who, after much cajoling, allowed herself to be taped recounting both her story and the Hinilawod. It took three weeks to complete the recording of the 30-hour epic poem.
A concise version of the story of Hinilawod can be found in the book Philippine Mythology authored by Jocano.
Hinilawod, recounts the story of the exploits of three Suludnon demigod brothers: Labaw Donggon, Humadapnon and Dumalapdap of ancient Panay.
