The Sonpi Bunmyaku does not mention a "Fujiwara no Atsutaka", but it includes a reference to "Mokunosuke Atsutaka" (木工助敦隆), son of "Tachibana no Toshikiyo" (橘俊清).[1] Atsutaka's court position was Mokunosuke (assistant director of the Mokuryō 木工寮),[2] and his father's name was the same, so it is believed that these two were the same individual.[1][a]
The Chūyūki records that he was assigned to the Mokunosuke post in Eichō 1 (1096).[1] He appears to have held this position until his death.[1]
According to the Chūyūki, Atsutaka died on the first day of the seventh month of Hōan 1 (27 July 1120).[2]
He participated in the Sanka Goban Uta-awase (山家五番歌合) in Tennin 3 (1110).[2] Counting both "Tachibana no Atsutaka" and "Fujiwara no Atsutaka", his name appears in the surviving records of four uta-awase contests from this period.[1] None of his poems, however, were included in any of the court anthologies.[1]
He was also noted for his scholarship,[2] and compiled the 20-volume Ruiju Koshū (類聚古集), a thematically arranged collection of Man'yōshū poems.[2] Sixteen volumes of the work are extant.[1]
Notes
^The Nihon Jinmei Daijiten Plus article on Atsutaka does not go into as much detail on sources, etc., but states that his real clan name was not Fujiwara but Tachibana.[3]
