Just as Galileo sought to interpret the phenomenon of comets in a way which supported Copernican heliocentricism, Chiaramonti explained it with the intention of supporting the traditional geocentric model. In 1621 he published a work called Antitycho which opposed the argument of Tycho Brahe that comets were celestial bodies following an orbit above the Moon. The "Antitycho" was lampooned by Galileo and Tycho Brahe The book offered here, de sede sublunari is a work supplementing his Antitycho, to which Tychonis Brahei replied in his Anti-Tychonem, in aciem productus a Ioanne Keplero, [etc.]. Frankfurt 1625. That work made 38.000 $ in 2001.
