Word History of Atlas

In Greek mythology, giants ruled the world in an early age. Their rule was overthrown after a mighty battle with other gods. Atlas was one of these giants, and after their defeat, the story goes, he was forced to hold up the sky on his shoulders. In the 16th century, the Flemish mapmaker Gerardus Mercator published a collection of maps. On the title page he showed a picture of Atlas supporting his burden. Mercator gave the book the title Atlas. Later collections of maps included similar pictures of Atlas, and came to be called atlases.
