Eutocius of Ascalon (; 480 – 540) was a Greek-speaking Palestinian mathematician who wrote commentaries on several Archimedean treatises and on the Apollonian ''Conics''. == Life and work == Little is known about the life of Eutocius. He was born in Ascalon, then in Palestina Prima. He wrote commentaries on Apollonius and on Archimedes. The surviving works of Eutocius are: *A Commentary on the first four books of the Conics of Apollonius. *Commentaries on: * *the ''Sphere and Cylinder'' of Archimedes. * *the ''Quadrature of the Circle'' of Archimedes (''In Archimedis circuli dimensionem'' in Latin). * *the ''Two Books on Equilibrium'' of Archimedes. Historians owe much of their knowledge of Archimedes' solution of a cubic by means of intersecting conics, alluded to in ''The Sphere and Cylinder'', to Eutocius and his commentaries. Eutocius dedicated his commentary on Apollonius' ''Conics'' to Anthemius of Tralles, also a mathematician, and architect of the Hagia Sophia patriarchal basilica in Constantinople.〔Boyer, p. 193. "Eutocius (born ca. 480), commented on several Archimedean treatises and on the Apollonian ''Conics''. It is to Eutocius that we owe the Archimedean solution of a cubic through intersecting conics, referred to in ''The Sphere and Cylinder'' but not otherwise extant except through the commentary of Eutocius. The commentary by Eutocius on the ''Conics'' of Apollonius was dedicated to Anthemius of Tralles (t534), an able mathematician and architect of St. Sophia of Constantinople."〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Eutocius of Ascalon」の詳細全文を読む スポンサード リンク
