伊勢物語
Concerning the exact date of composition and authorship there is only unresolved speculation. The identity of the nameless, idealised central character is unclear, though it is suggested to be Ariwara no Narihira (825–880). Thirty of the poems from "The Tales of Ise" appear in the "Kokin Wakashū" (905), with similar headnotes, all attributed to Narihira. The combination of these poems, and the similarity of some events in the tales to Narihira's life, have led to the additional suggestion that Narihira actually composed the work; however, the inclusion of material and events dating after 880 suggests otherwise.
