(Λειβηθρίδες), or nymphae Libethrides, a name of the Muses, which they derived from the well Libethra in Thrace; or, according to others, from the Thracian mountain Libethrus, where they had a grotto sacred to them. (Verg. Ecl. 7.21; Mela, 2.3; Strab. ix. p.410, x. p. 471.) Servius (ad Eclog. l.c.) derives the name from a poet Libethrus, and Pausanias (9.34.4) connects it with mount Libethrius in Boeotia. (Comp. Lycoph. 275; Varro, de Ling. Lat. 7.2.)
