吾妻鏡
Iso Mutsu was one of the first foreigners in Japan to understand that Kamakura's attraction lies in its extraordinary past and in its temples. She wrote her work after years of research, during which she interviewed temple abbots, high priests and monks. She also consulted Japanese texts, among them the famous Azuma Kagami, a medieval book that describes in great detail 80 years in the life of the city, and the Taiheiki, a medieval war epic.
