Fujiwara Sadaie (藤原定家), better-known as Fujiwara no Teika, was a Japanese poet, critic, calligrapher, novelist, anthologist, scribe, and scholar of the late Heian and early Kamakura periods. His influence was enormous, and he is counted as among the greatest of Japanese poets, and perhaps the greatest master of the waka form – an ancient poetic form consisting of five lines with a total of 31 syllables.
