Discourse on the Tides
''Discourse on the Tides'' (''Discorso Sul Flusso E Il Reflusso Del Mare'') is an essay written by Galileo Galilei in 1616 as a letter to Alessandro Orsini that explains the motion of Earth's tides as a consequence of Earth's rotation and revolution around the sun.〔Gigli, Rosella. "Galileo's Theory of the Tides." The Galileo Project, 1995. http://galileo.rice.edu/sci/observations/tides.html. Retrieved February 20, 2014〕 Though conclusively misguided and eventually discredited by theories addressing gravity, the essay represents the early lineage of tidal theory.
==Background==
Galileo's intrigue for tidal theory was motivated by a boat trip in 1595. While aboard a ferry carrying freshwater to Venice, Galileo noticed that the ship's cargo would undulate in accordance with the rocking of the ship.〔Tyson, Peter. "Galileo's Big Mistake." PBS, October 29, 2002. http://www.pbs.org/wgbh/nova/earth/galileo-big-mistake.html. Retrieved February 21, 2014〕
Galileo composed ''Discourse on the Tides'' while in Rome and appealing for papal acceptance of the teaching of Copernican theory. The letter is thus not just an explanation of tidal phenomenon but also a private confirmation and defense of Galileo's ideas on heliocentrism, which are discussed completely in his ''Dialogue Concerning the Two Chief World Systems''.
Galileo wished to present a convincing argument for heliocentrism. He was aware that all the astronomical arguments in the ''Dialogue'' were also consistent with the Tychonic system. Hence, his desire to present his theory of the tides which, he believed, provided clear evidence for the motion of the Earth.
