Joannes de Sacrobosco (English spelling)

Japanese: サクロボスコ（英語表記）Joannes de Sacrobosco

English mathematician and astronomer in the first half of the 13th century. Dates of birth and death unknown. His English name was John of Holywood, and Sacrobusco (or Sacrobusco) is a Latin translation of Holywood, Yorkshire, where he was born. He first studied at Oxford University, and later moved to Paris, where he became a teacher at the university, and died there. He wrote De spheres, General Calculus, and Ecclesiastical Calculus. The most famous of these is De spheres, compiled around 1233, which is based largely on Falgani's astronomical texts. Due to its concise and concise description, it was used as the standard textbook for Aristotelian-Ptolemaic geocentric cosmology until the first half of the 17th century, and had a great influence on intellectuals in the Latin world of Western Europe.

13世紀前半のイギリスの数学者，天文学者。生没年不詳。英名はJohn of Holywoodで，サクロボスコ(またはサクロブスコSacrobusco)という名は，彼の出身地ヨークシャーのホリウッドをラテン訳したもの。まずオックスフォード大学で学び，後にパリに出てパリ大学の教師となり，同地に没した。彼は《天球論》《一般計算法》および《教会暦算法》を著した。そのうち最も有名なものは1233年ごろ編まれた《天球論》で，多くをファルガーニーの天文書によっているが，その簡潔な要を得た叙述によって，17世紀前半まで，アリストテレス=プトレマイオス的な天動説宇宙論の基準的教科書として用いられ，西欧ラテン世界の知識人に大きな影響を与えた。
