While Hachiro NOMURA advocated a view that the tale would have been completed after 1220 based on the words in "Gukansho," 'I have heard there may be a little something of the sort,' so it seems difficult to know the process of writing "Hogen Monogatari" with this ambiguous record as a clue.
一方では、この『愚管抄』の「少々アル」を論拠に、物語の成立は1220年以降とみる野村八良のような見解もあり、この曖昧な記載から『保元物語』の成立をうかがい知るのは困難であろうと思われる。
