This view is in agreement with an opinion by Shigeru MATSUBARA, who identified the handwriting written in "Heiji Monogatari Ekotoba" (illustrated stories of the Heiji Rebellion) with that of FUJIWARA no Noriie in his later years, between 1249 and 1255.
これは絵巻である『平治物語絵詞』の書風を、藤原教家の晩年、建長年間（1249-1255）のものであると認定した松原茂の説とも合致している。
