Sahl bin Bishr (Zahel) and Masha'allah were two of the most influential medieval astrologers from the Arabic period. This essential work in medieval astrology translates 16 of their works, most for the first time, and includes many charts and lengthy introductory remarks and explanations by the translator.
A tour de force. The introduction to this volume is an evidence of the depth of Ben Dykes' conceptual and philosophical understanding of medieval astrology, and deserves to be a book in its own right. As in most of his translations, Ben Dykes once again makes us aware of the importance of engaging very closely with the rich language of these master craftsmen of the art.
