"Warrior noh: Konparu Zenpō and the ritual performance of shura plays" by Eric RathAlthough only some 6 per cent of the noh plays in the modern repertoire are shura plays, pieces that feature the ghosts of suffering warriors, these works are synonymous with ‘warrior noh’, and as a group they form one of the five main categories of plays. Prior studies have looked to the theoretical writings of noh's founder, Zeami (d. 1443), to explain why shura plays, though few in number, have come to represent the genre of warrior plays. However, this article contends that the theories of the actor and playwright Konparu Zenpō (1454–1532?) offer more persuasive reasons why shura plays became equated with warrior noh.
