What does atlas mean?
An atlas is a bound collection of maps, typically presenting the geography of the world or of a particular region through political, physical, and thematic mapping. The word most commonly denotes these reference volumes, ranging from pocket road atlases to comprehensive world atlases used in schools, libraries, and homes. The name comes from Atlas, the Titan of Greek mythology condemned to hold up the sky; early collections of maps were published under his image and title, and the association stuck. Beyond cartography, 'atlas' has a specialized anatomical meaning: it names the first cervical vertebra of the neck, which supports the skull — a fitting echo of the mythological burden-bearing. In architecture, an atlas can also be a sculpted male figure serving as a supporting column. The word carries connotations of knowledge, exploration, and orientation, and remains a familiar and evocative term for any authoritative compilation of maps.

Etymology of atlas
The word derives from Atlas, the Titan of Greek mythology who bore the heavens on his shoulders; the Greek name itself may relate to the verb 'to carry, bear'. It entered English via Latin in the late Middle Ages as a proper noun. Its modern use for a book of maps arose in the sixteenth century, when geographers such as Gerardus Mercator titled their map collections with images of the Titan, fixing the association between Atlas and cartography. Related English words from the same mythological root include Atlantic, Atlantis, and Atlantean.
