Abu Yusuf Ya'qub al-Kindi (Latinized name: Alkindus, d.874) was commissioned to translate ancient Greek philosophy and science into Arabic. He rapidly progressed to producing his own original treatises on a range of subjects covering both formal and natural sciences. al-Kindi is credited by Abu'l-Faraj al-Nadim in his Catalogue of Books al-Fihrist, with writing over two hundred and sixty books mainly on geometry, physics and philosophy. According to Khulusi, his publications greatly influenced later notable scholars[1] including the English scientist Roger Bacon (d.1294).[2][3]
