Johannes Kepler is considered to be the first scholar to have offered an adequate description of heavenly phenomena observed on the Moon's sky. Kepler outlined his ideas in his Somnium (The Dream), written originally in 1609, and subsequently printed in the years 1630/34. Kepler's lunar astronomy was to expose the absurdity of the arguments that the geocentric theatre of heavenly phenomena proves that the Earth remains motionless. In this paper, I argue that at the turn of the seventeenth century the idea of the sky observed from the Moon's surface was explored in cosmological discourse far more often than it has been assumed so far. My argument derives from the manuscript treatise Astrostereon (1603) authored by an English astrologer and physician, Edward Gresham. Writing for the same purpose as Kepler but several years earlier, Gresham laid down the foundation of lunar astronomy. I also demonstrate the uses of lunar astronomy in astrological almanacs printed in London at the time when Kepler's ideas were not widely known.

约翰内斯·开普勒被认为是第一个对月球天空上观察到的天象提供充分描述的学者。开普勒在他的Somnium ( The Dream ) 中概述了他的想法，最初写于 1609 年，随后在 1630/34 年印刷。开普勒的月球天文学是为了揭露天象的地心剧场证明地球静止不动的论点的荒谬性。在这篇论文中，我认为在 17 世纪之交，从月球表面观察到的天空这一概念在宇宙学论述中的探索次数远远超过了迄今为止的假设。我的论点来自手稿论文Astrostereon（1603 年）由英国占星家和医生 Edward Gresham 撰写。与开普勒的写作目的相同，但几年前，格雷沙姆奠定了月球天文学的基础。我还展示了月球天文学在伦敦印刷的占星术年鉴中的应用，当时开普勒的想法还没有广为人知。
