Summoning the Powers Beyond collects and reconstructs the old religions of preindustrial Micronesia. It draws mostly from written sources from the turn of the nineteenth century and the period immediately after World War II: reports of the Hamburg South Sea Expedition of 1908-1910, articles by German Roman Catholic missionaries in Micronesia included in the journal Anthropos, and reports by the Coordinated Investigation of Micronesian Anthropology (CIMA) and the American Board of Commissioners of the Foreign Missions (ABCFM). A detailed introduction and overview of Micronesian religion are followed by separate chapters detailing religion in the Chuukic-speaking islands, Pohnpei, Kosrae, the Marshall Islands, Yap, Palau, Kiribati, and Nauru. The Chamorro-speaking group of the Marianas is omitted because lengthy periods of intense military and missionary activity irradicated most of the local religion. The Polynesian outliers Nukuoro and Kapingamarangi are discussed at the end primarily to underscore the contrasts between Polynesian and Micronesian religion. In a concluding chapter, the author highlights the similarities and differences between the areas within Micronesia and then attempts an appreciation or evaluation of Micronesia religion. Finally, he addresses the evidence of a tentative hypothesis that Micronesian religion is sufficiently different from that of Polynesia and Melanesia to justify the continued claim of a separate Micronesian religion.
