Ἄτλας

In Hesiod's Theogony, written around 700 BCE, Atlas was a Titan who fought against Zeus in the cosmic war called the Titanomachy. When the Titans lost, Zeus punished Atlas with a singular sentence: hold the celestial sphere on his shoulders for eternity. The punishment was not death but endurance without end, a weight that could never be set down.

The Greeks named the Atlas Mountains in northwestern Africa after him, believing the range was the petrified Titan himself. Herodotus wrote of these mountains around 450 BCE. The sea beside them became the Atlantic. A single mythological figure had stamped his name across an entire geography long before anyone thought to bind maps in a book.

That came in 1595, when the Flemish cartographer Gerardus Mercator published a collection of maps with an engraving of Atlas holding a globe on the title page. Mercator did not invent the word for this kind of book—he simply placed the image there, and the public did the rest. Within a generation, any bound collection of maps was called an atlas.

The word has since expanded beyond cartography. Anatomists named the first cervical vertebra the atlas because it holds up the skull, just as the Titan held up the sky. In architecture, male figures supporting entablatures are called atlantes. A Titan's punishment became a metaphor for bearing impossible weight, then a publishing format, then a bone in your neck.
