This article examines al-Tusi's and Maghribi's recensions of Theodosius' Sphaerica by comparing their features and differences. Al-Tusi adheresto the original text of Sphaerica, however, by adding some postulates and three lemmas, he enriches the mathematical structure of the treatise. Al-Tusi's composition style reveals that he intended to prepare a pedagogical textbook, his statements are concise and precise and he presents demonstrations for all the theorems. Several manuscripts of al-Tusi's recension are extant, one of which has been transcribed before his death. The only other extant recension of Sphaerica belongs to Muhyeddin Maghribi. Maghribi changes the style of the original text by merging some theorems, changing the demonstrations and modifying the diagrams. Although he inserts some additional lemmas into the text, he leaves some simple proofs incomplete. One of the extant manuscripts of Maghribi's recension has been transcribed prior to his death. In sum, we can say that Tusi's recension enriches the mathematical content of the treatise, whereas Maghribi's recension includes some superfluous and superficial changes and lacks the mathematical force of Tusi's recension.
