大分縣豊後大野市には豊後國武將·緖方三廊惟榮の始祖誕生を序述する[祖母嶽傳說]が存在する。この傳說は、·古事記·に見える苧環型蛇籠入譚に屬する三輪山神婚說話と類似するもので、韓國の古代國の一つ、後百濟國の始祖由來 を緖述する[甄萱傳說]ともきわめて近似している。從來學界での苧環型蛇聾入譚についての硏究は、·古事記·收載の三 輪山神婚說話を中心に考察が行われ、豊後や日向地方を背景にしている[祖母嶽傳說]に中心を置いて考察した論考は皆 無に近いといえる。そこで本稿では、豊後國と日向國を舞台とする、·源平盛衰記·や·平家物語·收載のいわゆる、[祖母嶽傳說]に焦点をあてて檢討を試みた。特にその祖母嶽傳說が隣の國·韓國ではどのように展開されているのか、豊 後國や日向國の祖母嶽傳說や民間傳承の苧環型蛇聾入譚との比較を通して、倆傳承の特質を鐵文化の視点から明らかに している。また從來、學界では日本には卵生型氏族神話や卵生神話が綠遠いものとされてきたが、民間傳承の苧環型蛇 籠入譚のなかに密かに傳承されているのもはじめて指摘している。さらに後百濟國の始祖王の甄萱に[山の虎がて乳 を飮ませて育てた]と記す三國遺事·の記錄についても從來の學界では、虎に對する韓國人の固有信仰として捉える傾 向が强かったが、この趣向はすでに中國の雲南省の苧環型蛇籠入譚に見えるので、甄萱傳說への直接的な影響關係も檢 討する必要性が出てきた。

In the city of Bungo-Ono, Oita prefecture, there exists a Sobotake legend that describes the birth of the forefather of Ogatasaburokoreyoshi, a general of a country called Bungo. This legend not only draws parallels to the Mount Miwa-Shikon tale (A tale about a marriage between a god and a human) which is part of Odamakigata-Hebimukoiri(A tale about the use of a yarn ball to reveal a snake as a son-in-law) as it is found in Kojiki, it is also highly congruent with the Kyonhwon legend which depicts the advent of the Post-Baekje period . one of the ancient kingdoms of Korea. In the academia of the past, research on the Odamakigata-Hebimukoiri tale focused merely on the Mount Miwa legend. Therefore, a focus on the Sobotake legend set in Bungo and Hyuga is unprecedented. As such, this paper attempts to provide some first thoughts and perspectives on the Sabotake legend with Bungo and Hyuga at its center, which thus includes Genpejosuiki and Heike monogatari. This paper particularly aims to investigate how the Sabotake legend is depicted in neighboring Korea. Through a comparison of the Sabotake legend (based on Bungo and Hyuga) and Odamakigata-Hebimukoiri tale, the characterization of both is undertaken from the perspective of the ironware culture. Furthermore, according to past scholarship, the oviparity legend and the legend of oviparous clans were considered unrelated. This paper is the first of its kind to point out the implicit message behind the Odamakigata-Hebimukoiri tale. In addition, according to existing records of Samgukyusa which depicts Kyonhwon, the first king of the Post-Baekje period, as raised and fed by a tiger of the mountains, academia in the past had a strong tendency to focus on the special meanings of tigers to Koreans. However, such inclination make the legend strongly resemble the Odamakigata-Hebimukoiri tale from Unnansho, China. There is therefore a need to re-investigate the direct impact of the Kyonhwon legend.
