Anyway, there is no historical record before "Futsu-shodo shu," which leads one to assume the existence of this tale, so it is generally considered that the tale was completed before or after the Jokyo Disturbance; however, no evidence exists to prove it.
いずれにせよ、『普通唱導集』以前には、この物語の確実な存在を想定させる史料はなく、成立を承久の乱前後とみるのが通説であるが、確かな証拠は得られていない。
