This is a richly-illustrated study of 'The Oracles of the Three Shrines', the name given to a hanging scroll depicting three important Japanese shrine-deities and their respective oracle texts. The scroll has evolved continuously in Japan for 600 years, so different examples of it offer a series of 'windows' on developments in Japanese religious belief and practice.
Quite an interesting research on Sanja takusen. It opened for me a new page in the history of Gods' illustration in Shinto. Easy to understand with nice illustrations and explanations. That was a read for me.
