Rituals and daily life of the Yami (Tao), the Men Of-the-Island (Tao Do-Pongso) of Botel Tobago, a small coral island located off the coast of Taiwan (Lanyu), which I filmed in the 1970's, for the most part on silent Super 8 film. Their community practices include the irrigated cultivation of taro as well as dry cultivation such as millet, and fishing. These activities differ according the three seasons of the lunar year. The whole life of the islanders is centered on the fishing season of the migrating fish, in large and small pirogues - flying fish, dolphinfish and high sea fish - which takes place from March to July. Rites of opening are celebrated in order to "shape the port" (meyvanoa) and call the flying fish of the first migrations. Even though the Yami have been converted to Christianity, their ritual practices hinge on a vast category of entities : celestial divinities called "the Men From-Above (Tao Do-To), "the wandering souls" (anito) which inhabit the Yami Universe, and the "vital principles" animating the human body as well as the plants (millet), the animals (flying fish) or the sacred objects (gold pectorals).The collective power is gathered within the hands of the elderly who own goods (taros, pigs, gold, etc.). They act as middlemen for those of their lineage known as "those of one breath" during the ritual cérémonies, the sacrifices and the relations of exchange between the different groups. The exchanges do not imply only goods but also banquets, speeches and responsorial songs. The Yami have gone back to their original ethonym, Tao, following the ratification of the law on the identity of the Aborigènes (2001).
