Averroes was a prolific writer and his works, according to Fakhry, "covered a greater variety of subjects" than those of any of his predecessors in the East, including philosophy, medicine, jurisprudence or legal theory, and linguistics. Most of his writings were commentaries on or paraphrasings of the works of Aristotle that—especially the long ones—often contain his original thoughts. According to French author Ernest Renan, Averroes wrote at least 67 original works, including 28 works on philosophy, 20 on medicine, 8 on law, 5 on theology, and 4 on grammar, in addition to his commentaries on most of Aristotle's works and his commentary on Plato 's The Republic. Many of Averroes's works in Arabic did not survive, but their translations into Hebrew or Latin did. For example, of his long commentaries on Aristotle, only "a tiny handful of Arabic manuscript remains".
