Among the aborigines of Borneo whom I visited, with the possible exception of the Punan nomads, the belief in evil spirits and in good ones that counteract them, both called antoh, is universal, and to some extent has been adopted by the Malays. Though various tribes have their own designations (in the Duhoi (Ot-Danum) ùntu; Katingan, talúm; Kapuas, telún; Kahayan, kambae), still the name antoh is recognised throughout Dutch Borneo. Apprehension of evil being predominant in human minds, the word is enough to cause a shudder even to some Malays. There are many kinds of both evil and good antohs; some are male, some female, and they are invisible, like the wind, but have power to manifest themselves when they desire to do so. Though sometimes appearing as an animal or bird, an antoh usually assumes the shape of a man, though much larger than an ordinary human being. Caves in the mountains are favourite haunts of evil antohs. In the great rivers, like the Barito and the Katingan, are many of huge size, larger than those in the mountains. Trees, animals, and even all lifeless objects, are possessed by antohs good or bad. According to the Katingans the sun is a benevolent masculine antoh which sleeps at night. The moon is a feminine antoh, also beneficent. Stars are the children of the sun and moon--some good, some bad. To drive away malevolent antohs and attract benignant ones is the problem in the life philosophy of the Dayaks. The evil ones not only make him ill and cause his death, but they are at the bottom of all troubles in life. In order to attract the good ones sacrifices are made of a fowl, a pig, a water-buffalo, or, formerly, a slave. Hens' eggs may also be proffered, but usually as adjuncts to the sacrifice of an animal. If a child is ill the Katingan makes a vow that he will give Antoh from three to seven eggs or more if the child becomes well. If it fails to recover the offering is not made. The blood is the more precious part, which the Bahau of the Mahakam, and other tribes, offer plain as well as mixed with uncooked rice. The people eat the meat themselves, but some of it is offered to the well-disposed antoh and to the other one as well, for the Dayaks are determined to leave no stone unturned in their purpose of defeating the latter. The Duhoi (Ot-Danums) told me: "When fowl or babi are sacrificed we never forget to throw the blood and rice mixture toward the sun, moon, and 'three of the planets.'" With the Katingans the blian (priest-doctor) always drinks a little of the blood when an animal is sacrificed.
