Swords, Oaths, and Prophetic Visions investigates some of the most historically important political and social issues raised by the Genpei War (1180-1185). This epic civil conflict, which ushered in Japan's age of the warriors, is most famously articulated in the monumental narrative Heike monogatari (The Tale of the Heike). Elizabeth Oyler's ambitious work lays out the complex interconnections between the numerous variant texts of the Heike and the historical events they describe. But Oyler's innovative methodology also brings other texts and genres—the Gikeiki, the Soga monogatari, the Azuma kagami, and pieces from the kōwakamai (ballad-dramas) repertoire—into her analysis. Rather than concentrating on individual texts, Oyler focuses on the inter-textual relationships within this larger body of narrative and drama and the collective role of these works in creating and disseminating stories about some of the Genpei War's most contentious events. In so doing, she works toward a new understanding of the underlying cultural problems of which these tales are symptomatic and which they attempt to address.
