Abstract

This article focuses on how early modern astronomers and historians conceptualised the course of the history of astronomy. The aim is to describe the transition from the idea of closed historical cycles to the theory of infinite progress in astronomy. The cyclical Renaissance concept of the history of astronomy is addressed, highlighting in particular the emphasis placed by Protestant astronomers on the reliance of the history of astronomy on God. This is followed by a discussion of the theory of the origin of astronomy as proposed by 17th century astronomers; and then a clarification of the unusual combination of the cyclical and linear approaches, which emerged in the historiography of astronomy in the 17th century. The article concludes with a brief outline of the transition to the concept of infinite progress that occurred at the end of the 18th century.
