東アジアの言語と表象 文部科学省グローバルCOEプログラム 関西大学文化交渉学教育研究拠点 The Japanese art historian Toyomune Minamoto (1895-2001), known by proposing "the Aesthetic of Autumn Flowers" 「秋草の美学」) as being a unique characteristic of Japanese art, regarded the motif of“Autumn Flowers" as a representational symbol the Japanese aesthetic sense throughout art history. While according to Minamoto, this unique characteristic is based on the succession of the Yamato-e paintings as being an original and unique style of the Japanese paintings which was fully expressed by Rinpa School(琳派). So evidently, there should be some reason between the proposition of "the aesthetic of Autumn Flowers" and the valuation of Rinpa School by Minamoto. The meaning of the study and the valuation on Sotatsu Tawaraya (俵屋宗達) and Korin Ogata (尾形光琳) by Minamoto will be shown in conclusion. Analyzing and examining if there is any possible relation with Minamoto's decision to regard Pinpa School as the most representative style of the Japanese art are also the aim here.
