Show Summary Details


This chapter discusses the work of Christoph Scheiner on sunspots. It provides information on Scheiner's educational background and early career and highlights the influence of Galileo's Siderius Nuncius in his sunspot research. On the request of Augsburg magistrate and prefect Marc Welser, Scheiner first made a critical evaluation of the works of Galileo in 1610 under the name Apelles and later published his Rosa Ursina. He argued that sunspots were either fixed or wandering stars and that could either be the denser parts of some heaven or solid and opaque bodies existing in themselves.
