Alchabitius

Al-Qabisi, Abu Al Saqr (Alchabitius), astrologer, died 967

Al-Qabisi, who was born in Qabisa in today's Iraq, served as court astrologer to the famous Emir of Aleppo Sayf al-Dawla. His most important work is the "Al-Madkhal" ("Introduction to the Art of Jugdments of the Stars"). The Latin translations of the "Liber isagogicus", especially John of Seville's, proofed to be the authoritative introduction to astrology in the Middle Ages and the Renaissance. Significant comments from John of Saxony (1331) and Valentin Naboth contributed to the fame of the work.
