Yahya ibn Abi Mansur

Yahya ibn Abi Mansur (Arabic: یحیی ابن ابی منصور), also called Bizist, son of Firuzan (Persian: بزیست فیروزان; d. 830) was a senior Persian^[1] official from the Banu al-Munajjim family, who served as an astronomer and an astrologer at the court of Abbasid caliph al-Ma'mun. Since his father Abu Mansur Aban was an astrologer in service of caliph al-Mansur, it can be concluded that Yahya spent his childhood in Baghdad.
