陸機と「楚」 : 聲律意識の形成について

Abstract

While Lu Ji 陸機 was considered as the precursor referring to the metre in his Wen fu 文賦, the literal critics in the Six Dynasties 六朝 often consider that the sounds in the works of Lu Ji and Lu Yun 陸雲 are "Chu." It suggests that their metre were different from their contemporaries. However it has not been obvious what this term "Chu" signifies. The present paper inspects Lu Yun's The Letters to Brother 與平原書, in which Zhang Hua 張華 labels the sounds of Lu Ji "Chu", and analyze their rhyme style in poetry and proses. Through this examination, unusual peculiarities are found out in their rhyme, which is different from the north literati in that time, but is rather common to some from Wu 呉, which is Lu brothers' native place. Moreover Lu Yun's letters suggested that Lu Ji and Lu Yun seemed to have some common standard in rhyme style. Lu Yun said, "rhyme in Xian 獻 and Yan 宴 followed Wang Can's 王粲 example, " "I know both Che 徹 and Cha 察 must not rhyme with Ri 日, but cannot find a right word, " and so on. In addition, Lu's acquaintances and surrounding environment must have influenced their rhyme style. Some literati entering to West Jin 西晉 government from Wu, who were Lu Ji's friends or juniors, are featured in the history books to be well versed in music. With this group of literati Lu Ji and Lu Yun may have gotten a chance to discuss the music, the works of poetry and prose, and the rhyme style of the north and south. Zhang Hua who always supported Lu brothers in the north was also a composer in the Music Bureau of West Jin government. Such an association surrounding Lu cultivated his keen sense of the metre in verse.
