It was there, 18 centuries before the Copernican revolution, that Aristarchus posited a heliocentric solar system and Eratosthenes calculated the circumference of the Earth.

One day the moon rises, the earth revolution to one year, would like one to twenty-four hours, love a man to life, but an intimate blessing as long as the second: happy year of the rooster!

Half of the days of the earth revolution multiplies half of the earth's revolution is the revolution of the sun.
