In antiquity, Lebadeia was a town near the western frontier of ancient Boeotia, described by Strabo as lying between Mount Helicon and Chaeroneia. The ancient town was situated at the foot of a precipitous height, which is an abrupt northerly termination of Mt. Helicon. Pausanias relates that this height was originally occupied by the Homeric city of Mideia, from where the inhabitants, under the conduct of Lebadus, an Athenian, migrated into the plain, and founded there the city named after him. On the other hand, Strabo maintains that the Homeric cities Arne and Mideia were both swallowed up by Lake Copais.
