Shlomo Sela is a lecturer in the Department of Jewish Philosophy at Bar-Ilan University. His research focuses on Jewish attitudes toward the sciences, with special interest in the history of astrology in the Middle Ages. He has recently published: Abraham Ibn Ezra: The Book of Reasons, A Parallel Hebrew-English Critical Edition of the Two Versions of the Text (Brill, 2007), and Abraham Ibn Ezra: The Book of the World, A Parallel Hebrew-English Critical Edition of the Two Versions of the Text (Brill, 2010). With this volume he continues the publication of Ibn Ezra’s complete works on astrology.

"Shlomo Sela is to be congratulated for making Ibn Ezra’s astrological treatises available in a modern edition of very high quality." Bernard Goldstein, University of Pittsburgh"[W]hat Sela has done here and is doing in this series is simply invaluable. Not only does he open up the astrological thought of Ibn Ezra himself, but he provides a doorway to the Arabic astrological tradition. Explaining technical terms, giving their history and the context of their transmission, he is contributing greatly not only to scholars of medieval Hebrew thought but to anyone interested in making sense of the basic concepts and practices of medieval astrology."Maud Kozodoy.
