Page "Heliocentrism" Paragraph 23

The Jesuit astronomers in Rome were at first unreceptive to Tycho's system ; the most prominent, Clavius, commented that Tycho was " confusing all of astronomy, because he wants to have Mars lower than the Sun.

" However, after the advent of the telescope showed problems with some geocentric models ( by demonstrating that Venus circles the sun, for example ), the Tychonic system and variations on that system became very popular among geocentrists, and the Jesuit astronomer Giovanni Battista Riccioli would continue Tycho's use of physics, stellar astronomy ( now with a telescope ), and religion to argue against heliocentrism and for Tycho's system well into the seventeenth century ( see Riccioli ).
