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.
Medievalism Medievalism is the system of belief and practice characteristic of the Middle Ages, or devotion to elements of that period, which has been expressed in areas such as architecture, literature, music, art, philosophy, scholarship, and various vehicles of popular culture. Since the eighteenth century, a variety of movements have used the medieval period as a model or inspiration for creative activity, including Romanticism, the Gothic revival, the Pre-Raphaelite and arts and crafts movements and neo-medievalism (a term often used interchangeably with medievalism). The words "medievalism" and "Medieval" are both first recorded in the nineteenth century. "Medieval" is derived from Latin "medium aevum" (middle of the ages).
