ابن سهل
H. Floris Cohen's historiography of the scientific revolution ("How Modern Science Came into the World") credits the Umayyad caliphates and especially the Abbasid caliphates support for the translation movement from the Greek, Persian, and Syriac literature to Arabic. These translations were undertaken by the library of the House of Wisdom in Bagdhad. Al-Kindi, Al-Battani, Ibn Sahl and Ibn al-Haytham flourished under the liberal policies of these caliphates.
