It has been called “the most singular centaur that religion and science have ever produced” (Franz Boll). Astrology as a cultural form has puzzled and fascinated generations of humankind. It reached its apogee in the European Renaissance, when it flourished in literature, political expression, medicine, art, and all the other areas of endeavor catalogued in this unique collection. Brill’s Companion to Renaissance Astrology brings together a wide array of expertise from around the globe to explain the method and matter of this cultural form, including the Arab and Classical heritage, the medieval tradition, the clash with organized religion, the influence on knowledge and the competition with newly emerging ways of knowing, summarizing the current state of research and suggesting new paths.
