Fujiwara no Sukemasa (藤原佐理)
He held positions within Konoefu (the Headquarters of the Inner Palace Guards), Sangi (councilor), Hyobukyo (Minister of Hyobusho Ministry of Military) and Dazai no daini (Senior Assistant Governor-General of the Dazai-fu offices), before being conferred Shosanmi (Senior Third Rank). He was known as a calligrapher, especially in cursive script calligraphy, and wrote on shikishigata (colored-paper) on a folding screen for Daijoe (banquet on the occasion of the first ceremonial offering of rice by the newly-enthroned emperor) for Emperor Enyu, Emperor Kazan and Emperor Ichijo. He was considered to be one of the three best calligraphers among ONO no Michikaze and FUJIWARA no Yukinari, and his flowing and dynamic calligraphy style was called 'Saseki' style. Some letters such as 'Shikaishi' (national treasure), 'Rirakujo' (Leaving the capital) (national treasure) still exist in the form of autographs. In "Okagami" (The Great Mirror), Sukemasa was written as "Nyodeijin" which meant a sloppy man, because he made a lot of mistakes while drunk. It is said that he was very sloppy with work and lacking in common sense. Therefore, most his letters left such as 'Rirakujo' were apologetic letters.
