本論文主要是探討谷崎作品「柳湯的事件」與志賀作品「混沌的腦筋」之間的影響關係。谷崎在大正~昭和時期創作了許多偵探作品。谷崎與其他情偵探小說作家的關係上,研究史上大多論及與美國作家艾德嘉‧愛倫波(エドガー‧アラン‧ポー)之間的關係。其主要原因來自於谷崎在作品中曾實際提及艾德嘉‧愛倫波的作品名。因此,在研究史上,把這些視為一個重要參考指標而進行論述的研究文獻,則不在少數。也就是把實際谷崎具體舉出的艾德嘉‧愛倫波作品名為一線索,探討艾德嘉‧愛倫波作品對谷崎作品所產生的影響。然而,調查發現﹒志賀的「混沌的腦筋」作品,有許多小說要素,直接或間接地反映在谷崎的作品「柳湯的事件」中。但兩篇作品在作中人物的關係設定、作品表現方式雖都極其相似,卻在研究史上未曾被提及。檢閱谷崎日後的言論,也完全沒有提及志賀的這篇作品。研究方法上,以文本閱讀的方式,解讀這兩篇作品。而透過谷崎作品中所呈現的〈志賀〉要素,這樣的觀點來探討,才能找到存在於志賀與谷崎兩者在創作方法中本質上的實質問題。
This dissertation is mainly discussing the interface between Tanizaki's ”Yanagiyunoziken” and Siga's ”Nigottaatama”. Tanizaki produced a lot of detective fiction during the Taisho period to the Syouwa period. When coming to the relationship between Tanizaki and other detective writers' works, mostly the studies concentrated on the relation with the American author, Edgar Allan Poe. The main reason was due to that Tanizaki had mentioned the name of Edgar Allan Poe's fiction in his writing. Thus, many researchers deemed it an important reference resource to discuss in the history of research. It's also a clue if we want to probe into the influence of Allan Poe's work s on Tanizaki's fictions.In fact, Siga's ”Nigottaatama” contains lots of novel factors, which reflect on Tanizaki's ”Yanagiyunoziken” directly or indirectly, according to the investigation. Though the character design and express style in two fictions are very similar, there's seldom mentioned in the history of research. Reviewing Tanizaki's later statement, there's no other mention of Siga's work.In the way to research, I will interpret these two fictions by text reading. Thro ugh the essential of ”Siga” appeared in Tanizaki's fiction, there will be a possible way to find out the essence of the real problem existing in Tanizaki and Siga's creative writing style.
