The Works of Galileo

Sunspots and Floating Bodies

Scheiner, Rosa Ursina (1630)

Scheiner eventually published the definitive work of the 17th century on sunspots, Rosa Ursina (1630) (Figure 1) . In this book Scheiner ridiculed Galileo while accepting Galileo’s argument that sunspots lie on the surface of the sun (Figure 2) (Figure 3) (Figure 4) .

Scheiner became an implacable enemy of Galileo, resentful of Galileo’s patronizing invective in the Letters on Sunspots (1613) and jealous of his priority claims for the discovery of sunspots.
