Gods In The Sky: Part 2 (2012x55)

And the freedom that came from trade allowed them to question and reason. As a result they became the greatest astronomers of the ancient world - the Greeks not only knew that the earth was round, they also knew its size, and even successfully calculated the distance of the moon from the earth.
