The Abbasid Caliphate sponsored these translations and the caliphs took a personal interest in the work of the translators, which preserved that knowledge in Arabic texts. There were two main circles of translators in Baghdad, centered on the scholars Hunayn ibn Ishaq and al-Kindi, respectively. Having mastered Arabic, Syriac, Greek and Persian, Hunayn translated no fewer than 116 works, especially medical and scientific texts.
