This volume offers the first critical edition of the Hebrew text, with English translation and commentary, of seven astrological treatises by Abraham Ibn Ezra: the Book of Elections (3 versions); the Book of Interrogations (3 versions); and the Book of the Luminaries. This volume, then, covers the astrological doctrine of elections, which is concerned with finding the best time to begin a particular activity; the doctrine of interrogations, designed to allow astrologers to reply to questions related to daily life; and the astrological theory behind the doctrine of the critical days, when marked changes take place in the symptoms of a disease. These three systems of astrology were combined in a single volume because Ibn Ezra considers them to be closely interrelated.

"Despite these quibbles, Shlomo Sela is to be congratulated for making Ibn Ezra’s astrological treatises available in a modern edition of very high quality."
