=== Astrology ===
Ibn Ezra composed his first book on astrology in Italy, before his move to France:
* ''Mishpetai ha-Mazzelot'' ("Judgments of the Zodiacal Signs"), on the general principles of astrology

In seven books written in [[Béziers]] in 1147–1148 Ibn Ezra then composed a systematic presentation of astrology, starting with an introduction and a book on general principles, and then five books on particular branches of the subject. The presentation appears to have been planned as an integrated whole, with cross-references, including references to subsequent books in the future tense. Each of the books is known in two versions, so it seems that Ibn Ezra also created a revised edition of the series at some point.<ref>Shlomo Sela (2000), "Encyclopedic aspects of Ibn Ezra's scientific corpus", in Steven Harvey (ed), ''The Medieval Hebrew Encyclopedias of Science and Philosophy: Proceedings of the Bar-Ilan University Conference'', Springer. {{ISBN|0-7923-6242-X}}.
