10. _____ He said the Gods made the Earth, it was a perfect round sphere--but he couldn't
11. _____ He used the Earth's shadow during a lunar eclipse to show that Earth was round.
12. _____ He was the first to figure that the Sun was larger than the Earth and thus was
probably at the center of our Solar System.
13. _____ He used simple geometry and shadows to accurately estimate the Earth’s
14. _____ He created a geocentric model of the Solar System that included epicycles which
Actually predicted planetary motion very well.
15. _____ He said the Earth was round because a traveler moving south saw new stars that had
been hidden below the equator.
