/ˈæt.ləs/·noun·1636 CE (OED; English use of 'atlas' as a bound book of maps, derived from Mercator's 1595 Latin title)·Established
Origin
From Greek Ἄτλας ('the bearer', from PIE *telh₂-, to endure), a Titan condemned to hold up the sky, whose image on Gerardus Mercator's 1595 map collection became the generic word for any bound collection of maps — connecting, through one root, tolerate, talent, tantalize, and a vertebra that holds up the skull.
Definition
A bound collection of maps, or the topmost cervical vertebra supporting the skull, both named after Atlas, the Titan of Greek myth condemned to bear the heavens on his shoulders, whose name derives from PIE *telh₂- (to bear, endure).
The Full Story
GreekAncient Greek, with English adoption in 1636well-attested
The word 'atlas' (a bound collection of maps) derives from Atlas (Greek Ἄτλας), a Titan in Greek mythology condemned by Zeus to bear the heavens on his shoulders as punishment for leading the Titans against the Olympians. The name Atlas itself is generally derived from PIE *telh₂- (to lift, carry, bear, endure), making Atlas literally 'the bearer' or 'the enduring one'. TheAtticGreek
Did you know?
ThePIE root *telh₂- (to bear, endure) gave Greek the Titan Atlas ('the bearer'), Latin tolerare ('to endure' → tolerate), Greek talanton ('weight on a balance' → talent), and the name Tantalus ('the sufferer' → tantalize). One root covers a condemned Titan, a cardinal virtue, a unit of currency, and the punishment of perpetual frustration — all because the ancient world organised these ideas around a single concept: carrying a weight you cannot put down.
de Fabrica Mundi. Mercator chose Atlas not merely for the mythological figure but explicitly as a tribute to a legendary King Atlas of Mauretania, described in ancient sources as a philosopher and astronomer who supposedly made the first celestial globe. The work was completed posthumously and published in 1595 by his son Rumold Mercator. English adoption of 'atlas' in the map-book sense is first recorded in 1636 (OED). The same PIE root *telh₂- also yields: Greek τλῆναι (tlēnai, to endure), Greek τάλαντον (talanton, a balance, a weight — hence 'talent'), Latin tolerāre (to bear, endure — hence 'tolerate'), Latin tollere (to lift, raise), and possibly Tantalus (Τάνταλος), whose name may encode the sense of 'the much-suffering one'. From Atlas also come: Atlantic Ocean (the sea near the Atlas mountains or Atlas's domain), Atlantis (the island of Atlas, as in Plato's dialogues), and atlas vertebra (the first cervical vertebra, named by anatomist Andreas Vesalius in 1543, by analogy with Atlas supporting the skull as Atlas supported the heavens). Key roots: *telh₂- (Proto-Indo-European: "to lift, carry, bear, endure — the zero-grade *tl̥h₂- yields Greek ἄτλας (bearer); full grade *telh₂- yields Latin tolerāre and Greek τάλαντον"), Ἄτλας (Átlās) (Ancient Greek: "the Titan condemned to bear the heavens; agentive noun from *telh₂-, meaning 'the bearer' or 'the enduring one'"), Atlas (New Latin: "Mercator's chosen title for his 1595 cosmographical map collection, honouring both the myth and the legendary Mauretanian king-astronomer").
