Angalo is the colossal giant of Ilocano origin lore, a landscape-shaping being whose body and labours account for the features of the Ilocos country. In the etiological tales gathered from the nineteenth century onward, his footprints scoop out valleys and lakes, the earth he piles becomes the mountain ranges, and the great furrows he digs fill to become the rivers; some tellings derive the sea itself from his exertions. He is regularly paired with the giantess Aran, and from the two the Ilocano people are said to descend. A number of accounts make him the agent or offspring of the creator, so that the abstract making of Namarsua is worked out concretely in the giant's world-shaping deeds.
