Content

Arabic version of the De sphaericis (كتاب الأكر) by Theodosius of Bithynia (ثاودوسيوس; Θεοδόσιος; c 160-c 100 BC). The preface (f. 1v, lines 3-5, transcribed below) states that it was translated from Greek into Arabic by Qusṭā ibn Lūqā (قسطا بن لوقا; c 820-912), up to Chapter 3, figure 5, at the order of Abū al-‘Abbās Aḥmad (أبو العباس أحمد) son of the caliph al-Mu‘taṣim bi-llāh (المعتصم بالله; reg. 833-842), that the rest was translated by another, and that the translation was corrected by Thābit ibn Qurrah (ثابت ابن قرة; d. 901).
