The great medieval compendium of Persian and Arabic masters
The Book of the Nine Judges is the largest traditional compilation of horary astrology, drawn from nine Persian and Arabic astrologers. Translated from Arabic sources chiefly by the 12th-Century Latin translator Hugo of Santalla, it achieved legendary status but has never before been translated into any modern language. It includes material by Masha’allah, ‘Umar al-Tabari, Abu Ma’shar, Sahl bin Bishr, al-Kindi, Abu ‘Ali al-Khayyat, “Dorotheus,” “Aristotle,” and Jirjis. Click here for a PDF excerpt.
