Pierwsza biografia gubińskiego astronoma. Kilka uwag na marginesie książki Gottfried Kirch (1639–1710) – Astronom, Kalendermacher, Pietist, Frühaufklärer

Klaus-Dieter Herbst, Gottfried Kirch (1639–1710) – Astronom, Kalendermacher, Pietist, Frühaufklärer, Jena 2022 (Acta Calendariographica – Forschungsberichte, t. 10), ss. 737. The first biography devoted to Gottfried Kirch (1639–1710), an astronomer from Gubin, a calendar-maker and author of ephemerides, was published in 2022. It is the result of many years of research on Kirch by Klaus-Dieter Herbst. The book presents the astronomer’s life and explores the various stages of his career. In addition to the biographical details and reconstruction of Kirch’s network, Herbst focuses on two key areas of the protagonist’s work: astronomy and calendars. In this article, I examine a few minor shortcomings in Herbst’s interpretation of Kirch’s observation journal and suggest several additions and emendations that could be considered for the book’s second edition.
