As mentioned above, the version which is considered to be the oldest is said to have been made in 805, but the original version no longer exists and the version which has been handed down to today is the copy made by Teikan TO (FUJII or FUJIHARA, 1732-1797), a researcher of Yusoku-kojitsu (knowledge of court rules, ceremony, decorum and records of the past) and some additions inconsistent with the realty of 805 are recognized (and it is unknown whether the additions were made by Teikan TO or somebody else before him).
前述のように最古の行基図とされているのは、延暦24年作成と伝えられているものであるが、原図は既に亡く、現在伝わるものは江戸時代の有職故実研究家藤貞幹（藤井・藤原とも、1732年－1797年）の写しのものであり、かつ延暦24年の実情と不一致の加筆が見られる（これが藤貞幹によるものか、それ以前からのものなのかは不詳）。
