Abraham ibn Ezra was a follower of astrology, which he calls "a sublime science." Besides translating another Jewish philosopher Mashallah's astrological work "Questions" and another work of this author on the eclipse of the moon from the Arabic into Hebrew, he wrote "Nativity", "Sentences of the Constellations", "Reshit Hokhmah" ("Beginning of Wisdom"), "Book of the World", a treatise on the "Planets", a treatise on the "Luminaries", and a horoscope. He often refers to astrology in his Bible commentaries. To him heaven with its constellations is "the book of life," in which man's destiny is written, and against which there is recourse to God as "the Almighty," who overrules all these influences. A modern scholar summarizes Ibn Ezra's attitude as follows: "The deity has delegated to the stars the governance of the sublunar world. Israel however, enjoys a special status, which is manifest most decisively in its possession of the Torah. As long as a Jew is engaged in the study and observance of the Torah, he is linked to a spiritual realm which is itself superior to the stars. In this way a Jew may liberate himself from the decrees of the stars."
