能因の「想像奥州十首」に関する試論 - 家集での位相及び詠歌契機 -

Abstract

In the present article, I explore the significances of Noin’s trip to Mutsu for the poet himself, a figure who produced works in the midst of Heian period. To this end, I analyse a set of poems collected in the intermediate volume of Noinshu, a collection of Noin’s poems selected by the poet himself. Noin is famous for his countless trips, and among them, of particular note is his trip to Mutsu. It is generally perceived that Noinshu indicates that he tripped to Mutsu twice, but it seems plausible to assume that he attempted his third trip to Mutsu, an assumption based on the 139th poem, the 140th–149th poems entitled Sozo Oshu Jushu, and the 158th poem in the latter half of the intermediate volume of Noinshu. My contention is as follows: (i) Noin planed his third trip to Mutsu via Tokaido, (ii) this plan fell through because of the Revolt of Taira-no Tadatsune, which happened in 1028 and lasted for three and half years, and (iii) he solaced himself with the creation of Sozo Oshu Jushu. It is not possible to confirm that he really tripped to Mutsu for the third time because immediately after the 158th poem featuring the “Bridge of Hamana”, he starts to write about “Kayanoin Utaawase” from the 159th poem on. Still, the reason why Noinshu does not contain any poem concerning his third trip to Mutsu seems to be that Noin intentionally did not include it in his poem collection as he intentionally included only a single poem concerning his first trip to Mutsu.
