Majrīṭī: Abū al-Qāsim Maslama ibn Aḥmad al-Ḥāsib al-Faraḍī al-Majrīṭī

Maslama al-Majrīṭī was considered by his Andalusian contemporaries as the foremost authority of his time in the field of astronomy. His achievements are mainly in the field of mathematical astronomy, although it is known that he wrote on commercial arithmetic (muҁ āmalāt) and was also a renowned astrologer. In addition to his own compositions, Majrīṭī’s importance lies within the context of Andalusian science and his activity in scientific teaching. Majrīṭī was the founder of an original school of Andalusian astronomers in which the disciplines of arithmetic and geometry were also cultivated.
