Sadanobu Fujiwara

Fujiwara no Sadanobu(藤原定信, 1088–1156) was a Heian period calligrapher. He is known primarily for his hiragana poetry transcriptions. He came from the Sesson-ji lineage of calligraphers as the son of Fujiwara no Sadazane and fifth-generation descendant of its founder, Fujiwara no Yukinari. He is said to have been a very fast and graceful writer, and that he copied the entire Issaikyo, the body of all Buddhist literature, in 23 years.
