和歌に師匠なし。たゞ旧き歌をもつて師となす。心を古風に染め、詞を先達に習はば、誰人かこれを詠ぜざらんや。 — Fujiwara no Teika

Fujiwara no Sadaie or Teika was a Japanese anthologist, calligrapher, literary critic, novelist, poet, and scribe 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.
