Averroes was a philosopher under which philosophical movements  such as Aristotelianism and the 13th-century philosophical movement  came into play in what other religions beside Islam?
Averroes Ibn Rushd (Arabic: ‎ ‎ ; 14 April 1126 – 10 December 1198), full name (Arabic: أبو الوليد محمد ابن احمد ابن رشد‎ , "ʾAbū l-Walīd Muḥammad Ibn ʾAḥmad Ibn Rushd " ‎ ), often Latinized as Averroes ( ), was a medieval Andalusian polymath. He wrote on logic, Aristotelian and Islamic philosophy, theology, the Maliki school of Islamic jurisprudence, psychology, political and Andalusian classical music theory, geography, mathematics, and the mediæval sciences of medicine, astronomy, physics, and celestial mechanics. Ibn Rushd was born in Córdoba, Al Andalus (present-day Spain), and died at Marrakesh in present-day Morocco. His body was interred in his family tomb at Córdoba. The 13th-century philosophical movement in Latin Christian and Jewish tradition based on Ibn Rushd's work is called Averroism.
Methodic school The Methodic school of medicine ("Methodics", "Methodists", or "Methodici", Greek: Μεθοδικοί ) was an ancient school of medicine in ancient Greece and Rome. The Methodic school arose in reaction to both the Empiric school and the Dogmatic school (sometimes referred to as the Rationalist school). While the exact origins of the Methodic school are shrouded in some controversy, its doctrines are fairly well documented. Sextus Empiricus points to the school's common ground with Pyrrhonism, in that it “follow[s] the appearances and take[s] from these whatever seems expedient.”
