  Marathesium (Marthesion: Eth. Marathesios an Ionian town on the coast of Lydia, south of Ephesus, and not far from the frontiers of Caria, whence Stephanus (s. v.) calls it a town of Caria. (Scylax, p. 37; Plin. H. N. v. 31.) The town at one time belonged to the Samians; but they made an exchange, and, giving it up to the Ephesians, received Neapolis in return. (Strab. xiv. p. 639.) Col. Leake (Asia Minor, p. 261) believes that a few ancient ruins found at a place called Skalcanova mark the site of Marathesium, though others regard them as remains of Pygela.
