Before taking up the mythology proper, we should have some idea of the religion as a whole. These peoples believe that the regions of the sky world, earth world, and underworld are peopled by an almost incalculable number of deities of varying character and powers. Some of these deities are the great beings who inspire the phenomena of nature, while others are guardian spirits, messenger spirits, or mischievous tricksters. The great nature deities are mostly of malevolent character, and are much feared. Ancestral souls and the souls of sacred animals are looked upon as mediators between gods and men. Pigs and chickens are sacrificed to the deities, and other articles of food and drink are provided for them. Many elaborate religious feasts and ceremonies are held at which priests officiate. The priests form a well-defined class, and in some districts there are also priestesses. A religious ceremony is required for every important act of life, and the priests and priestesses are usually busy people. It would seem that a religion of this same general type was also common among the lowland peoples of the Philippines before they were Christianized by the Spaniards. Pigafetta, the first European to write of the Philippines, describes a ceremony, which he saw performed in Cebu in the year 1520, as follows: [21] In order that your most illustrious Lordship may know the ceremonies that those people use in consecrating the swine, they first sound those large gongs.

One bit of cloth of Cambaia is spread on the ground. Then two very old women come, each of whom has a bamboo trumpet in her hand. When they have stepped upon the cloth they make obeisance to the sun. Then they wrap the cloths about themselves. One of them puts a kerchief with two horns on her forehead, and takes another kerchief in her hands, and dancing and blowing upon her trumpet, she thereby calls out to the sun. The other takes one of the standards and dances and blows on her trumpet. They dance and call out thus for a little space, saying many things between themselves to the sun. She with the kerchief takes the other standard, and lets the kerchief drop, and both blowing on their trumpets for a long time, dance about the bound hog. She with the horns always speaks covertly to the sun, and the other answers her. A cup of wine is presented to her of the horns, and she dancing and repeating certain words, while the other answers her, and making pretense four or five times of drinking the wine, sprinkles it upon the heart of the hog. Then she immediately begins to dance again. A lance is given to the same woman. She shaking it and repeating certain words,
