This document provides an introduction to a survey of Philippine folk epics. It outlines the contents and objectives of the survey, which are to review materials on long heroic narratives found in the Philippines, determine their folk origins and epic characteristics, discover common features, indicate their number and availability, and provide summaries. It notes that only a few such epics were documented during the Spanish period, but fieldwork since the early 1900s has uncovered more examples, especially among non-Christian peoples. The introduction establishes criteria for defining Philippine folk epics.
