First collected edition of a systematic presentation of astrology composed by the celebrated Jewish polymath Abraham ibn Ezra. Originally written in Hebrew at Béziers between 1146 and 1148, the present compilation includes an introduction, a book on general principles, and five books on particular branches of the subject. It derives chiefly from the Latin translation made at the close of the thirteenth-century by Pietro d'Abano. The French version of 1273 upon which d'Abano's translation is based, was also translated into Latin by Henry Bate and Arnoul de Quinquempoix (Levy & Cantera). "The presentation appears to have been planned as an integrated whole, with cross-references throughout, including references to subsequent books in the future tense. Each of the books is known in two versions, so it seems that at some point Ibn Ezra also created a revised edition of the series" (Sela).

In addition to the numerous references to matters astrological which can be found scattered throughout Ibn Ezra's biblical commentaries, the works here collected comprise a virtual encyclopedia of judicial astrology. Their powerful influence is attested by both the survival of an extraordinary number of early manuscripts, and the wealth of citations in literature by Jewish and Christian savants throughout the early modern period. The Venetian printer Petrus Liechtenstein was active from 1498. While his list was heavy with liturgical works for export to central Europe, learned books in scientific fields comprised an important segment of his considerable production (Norton).
