Galilei, Galileo. Dialogue on the Great World Systems. Trans. Thomas Salusbury. Chicago: University of Chicago Press, 1953. Print.

• Galileo presents arguments for both the Ptolemaic and Copernican systems, though ultimately the arguments in favor of the Copernican system are stronger. This source is useful to my project because it outlines arguments in favor of both systems, allowing me to better understand each, and also because it is in itself a response to the Copernican theory, though it is scientific rather than literary.
