A reference to Fujiwara no Kiyosuke 藤原清輔 (1104-1177), a well-known earlier poet and critic. Shunzei’s reference to Kiyosuke is calculated, because the latter was one of the founders of the Rokujō poetic house to which Kenshō belonged. By claiming Kiyosuke’s authority for his interpretation, Shunzei is making it difficult for Kenshō and the other Rokujō poets in the competition to challenge him, without disagreeing with their illustrious predecessor.
