This article is dedicated to the obscure Computus of Magister Cunestabulus (England, 1175), which offers a unique spotlight on the way the twelfth-century ‘Renaissance’ in mathematical astronomy impacted the Latin computistical tradition. Armed with an unusually broad array of sources newly translated from Arabic, among them Ptolemy’s Almagest, Cunestabulus applied his advanced knowledge in the service of traditional Latin learning and established Church doctrine, defending the non-existence of Antipodeans in the southern hemisphere as well as the astronomical foundations of the ecclesiastical computus. His intricate explanation of the error underlying the Julian calendar, which was based on the Arabic theory of the ‘access and recess of the eighth sphere’, makes for a technically sophisticated and conceptually intriguing case of Graeco-Arabic science being used for apologetic ends in twelfth-century Latin writing.

不情愿的创新者：古尼斯塔布斯魔导师计算机中的希腊-阿拉伯天文学（1175）


这篇文章献给了不起眼的 Magister Cunestabulus 的 Computus（英格兰，1175 年），它提供了一个独特的聚光灯，说明了 12 世纪数学天文学的“文艺复兴”对拉丁计算传统的影响。Cunestabulus 拥有一系列从阿拉伯语新译过来的异常广泛的资料，其中包括托勒密的天启，将他的先进知识应用于传统拉丁学习和建立的教会教义，捍卫南半球不存在对立面人以及教会计算机的天文基础。他对儒略历错误的错综复杂的解释，这是基于阿拉伯的“第八球体的进入和休止”理论，
