Today's mythology word is geology, which comes from the name of the Greek goddess Gaia, which is also the Greek word for the earth herself. To learn more about Gaia, see Wikipedia. There are many more words formed from this same Greek root: geography, geode, geodesic, geometry, geopolitcal, etc. The name "George" also contains the same root: "George" is from the Greek word georgos, "farmer," someone who works the earth (geo-ergos). This is a statue of Gaia in Lysá nad Labem (Czech Republic).
