I know of no close analogues to this etiological myth.
The hero of the tale, Ang-ngalo, is the same as the Aolo (Angalo) mentioned in the [notes to No. 3] (p. 27, footnote). Blumentritt (s.v.) writes, “Angangalo is the name of the Adam of the Ilocanos. He was a giant who created the world at the order of the supreme God.”
