《Dance Party》is a work that the so-called ‘Aesthetics works’ and ‘Works in enlightenment period’ of Ryunosuke Akutagawa are mixed and crossed, and a transitional work moving from ‘Aesthetic sworks’ to ‘Work in enlightenment period’. Therefore, this short story can be seen as either an ‘Aesthetics works’ or a ‘Works in enlightenment period’. If we consider《Dance Party》as a series of ‘Aesthetics works’ which Akutagawa has pursued so far, this work has compulsive force to complete the work as shown in the previous works. To find this point, this study compared and observed 〈Un Bal a Yeddo〉 and《Dance Party》which the author presumably used rough sketch. 〈Un Bal a Yeddo〉 is a record of personal experience which recorded the fact seen through Loti’s eyes. However, Akutagawa completed《Dance Party》reconstructing the work focusing on the evening party through making Akiko, a heroine, to meet and communicate with a French naval officer. In《Dance Party》「1」, Akiko’s fresh impression on the dance party and the boredom of life were described. The naval officer’s solitude watching the night sky of disappearing flame, darkness and artificial lighting between these two persons and its panorama. These are well depicted as much as we can say this panorama is a typical aesthetic of novel. Saying that ‘Artistic activity is conscious even for a genius’ and ‘Artist must learn technique even though he dislikes’, Akutagawa strived to acts of artificial and conscious creation. Finally, he asked what ‘life’ is for artist and makes his artistic viewpoint by completing ‘Aesthetics works’ as an answer for this question. And, it is connected to《Dance Party》. At the same time, he was advised by his teacher Soseki Natsume to reflect what he has made so far. Starting from《Dance Party》, he asked again deeply inside himself.《Dance Party》is a work reaching to the summit of ‘Aesthetics’ and reproaching himself what ‘the flame which he felt so beautiful as to raise sorrow’ was.
