Al‐Biṭrūjī (fl. 1185–1192) was an Andalusian astronomer whose complete name seems to be Abū Isḥāq (ibn?) al‐Biṭrūjī, Nūr al‐Dīn. Nothing is known about his biography apart from the fact that his name probably derives from the region of Los Pedroches, near Cordoba, and that he was a disciple of the philosopher Ibn ṭufayl (ca. 1110–1185).

On the other hand, al‐Biṭrūjī's treatise was translated into Latin by Michael Scott in Toledo in 1217.

Al‐Biṭrūjī was a member of the Andalusian school of Aristotelian philosophers composed of Ibn Bājja (1070?–1138), the aforementioned Ibn ṭufayl, Ibn Rushd (Averroes, 1126–1198), and Mūsā ibn Maymūn (Maimonides, 1135–1204). All these authors criticized Ptolemaic astronomy due to its mathematical character which did not agree with Aristotelian physics....
