The observatory of Ulugh Beg, erected in Samarqand in the 1420s, represents the culmination in the development of astronomical observatories in the Islamic world. After its rediscovery and excavation in the early twentieth century there have been several attempts to reconstruct its appearance and explain how it worked in detail, based on archaeological finds and the analysis of relevant manuscripts. A new look at illustrated copies of an important manuscript provides new, hitherto unmentioned details to the understanding of this instrument. Based on previous reports, we have created a virtual reconstruction of the observatory and the new version of the instrument, from which we have gained new insights.

撒马尔罕天文台主要仪器的新亮点

Ulugh Beg 天文台建于 1420 年代，是伊斯兰世界天文台发展的顶峰。在 20 世纪初重新发现和挖掘后，根据考古发现和相关手稿的分析，多次尝试重建其外观并详细解释其工作原理。重新审视一份重要手稿的插图副本，为理解该乐器提供了迄今为止未提及的新细节。根据之前的报告，我们对天文台和新版本的仪器进行了虚拟重建，从中我们获得了新的见解。
