In the book Gulliver's Travels (1726), Jonathan Swift tells a secret that the scientific world doesn't know and goes on to explain the two moons of Mars and he was pretty accurate although the moons were not discovered for over a hundred years later. One of the theories is that the Earth and Mars once had an orbital path that would bring them close enough to each other so one could actually see these moons. Mat explain why the early civilizations were terrified of Mars, the Red Planet, symbolic of war and evil. Mars is also tiled to Satan and the occult "Cube". Many sites on the search engines give some other theories.
