caryatid (n.)

1580s, in Greek mythology a member of the older family of Gods, later regarded as a Titan, son of Iapetus and Clymene; in either case supposed to uphold the pillars of heaven (or earth), which according to one version was his punishment for being war-leader of the Titans in their battle with the Olympian gods. "Originally the name of an Arcadian mountain god; the name was transferred to the mountain chain in Western Africa" [Beekes].

The Greek name traditionally is interpreted as "The Bearer (of the Heavens)," from a-, copulative prefix (see a- (3)), + stem of tlenai "to bear" (from PIE root *tele- "to lift, support, weigh"). But Beekes compares Berber adrar "mountain" and finds it plausible that the Greek name is a "folk-etymological reshaping" of this. Mount Atlas, in Mauritania, was important in Greek cosmology as a support of the heavens.
