Arne (Ancient Greek: Ἄρνη) was the chief city of the Aeolian Boeotians in ancient Thessaly, which was said to have derived its name from the mythological Arne, a daughter of Aeolus.^[1] The town was said to have been founded three generations before the Trojan War.^[2] According to Thucydides the Aeolian Boeotians were expelled from Arne by the Thessalians sixty years after the Trojan war, and settled in the country called Boeotia after them;^[3] but other writers, inverting the order of events, represent the Thessalian Arne as founded by Boeotians, who had been expelled from their country by the Pelasgians.^[4][5] Stephanus of Byzantium wrote that later Cierium occupied the site of Arne, which was accepted at least by William Smith, writing in the 19th century,^[6] and by the editors of the Barrington Atlas of the Greek and Roman World;^[7] others place Arne at a site nearby, but not at, Cierium.^[8] If Arne is Cierium, it is located at Pyrgos Kieriou (Πύργος Κιερίου), in the municipal unit of Arni, municipality of Sofades, periphery of Karditsa, Thessaly.^[7] Lund University's Digital Atlas of the Roman Empire, places Arne at Magoula Makria.^[8]
