On 'Astronomia'

This volume provides an edition, translation, and notes to Epistle 3: "On Astronomia," from the section on mathematics. The content is a mixture of elementary astronomy and astrology, but it is not a beginner's textbook; rather, the purpose is to use these disciplines for spiritual, moral, and soteriological guidance. Thus the Epistle uses the argument from design to show the necessity of a Creator who made this harmonious universe; the wondrous design is then employed by the authors as a paradigm for proper ethical, political, and even economic conduct.
