Ki no Tsurayuki
Thirty poems attributed to Narihira were included in the early 10th-century "Kokinshū", and many more in later anthologies, but the attributions are dubious. Ki no Tsurayuki mentioned Narihira in his "kana" preface to the "Kokinshū" as one of the Six Poetic Geniuses—important poets of an earlier age. He was also included in Fujiwara no Kintō's later Thirty-Six Poetic Geniuses.
