Abu Ma‘shar al-Balkhi, Latinized as Albumasar (also Albusar, Albuxar, Albumazar; full name Abū Maʿshar Jaʿfar ibn Muḥammad ibn ʿUmar al-Balkhī ابومَعْشَر جعفر بن محمد بن عمر بلخی; 10 August 787 – 9 March 886, AH 171–272), was an early Persian Muslim astrologer, thought to be the greatest astrologer of the Abbasid court in Baghdad. While he was not a major innovator, his practical manuals for training astrologers profoundly influenced Muslim intellectual history and, through translations, that of western Europe and Byzantium.
