Summary Understanding and influencing nature were preeminent aims of medieval Arabic science, and attracted European fascination with its accomplishments. This volume draws together studies on central themes, presenting a world of enquiry into the earth and the heavens, and ways to harness this information for divination and the occult sciences. It gives examples of how Arabic science travelled to Latin Europe through texts and instruments, and how it underwent transformation there as diverse fields were put to use and reinterpreted. The studies introduce a range of learning and perspectives: astrology conducted with planetary lots; a geography where features of the earth's surface move over time; knowledge of the elements and climates which Adelard of Bath learned from Arab masters; Avicenna's meteorology explaining the extremes of fire storms and catastrophic floods; debates about the eternity or creation of the world; evaluations of magic as a rational, intellectual discipline, or alternatively a danger needing censorship and linked to female witchcraft; and a precious astrolabe which in the Renaissance was reused and inspired new theoretical writings. Together these studies sketch a landscape of medieval Arabic science and Latin European engagement with this new frontier. TABLE OF CONTENTS Introduction Ab?
