 Strabo relates that it was a colony of Dorians from Megara, and that it was originally called Menebria (Μενεβρία) after its founder Menas; Stephanus of Byzantium says that its original name was Melsembria (Μελσημβρία), from its founder Melsas; and both writers state that the termination -bria was the Thracian word for town.According to the Anonymous Periplus of the Euxine Sea, Mesembria was founded by Chalcedonians at the time of the expedition of Darius against Scythia; but according to Herodotus it was founded a little later, after the suppression of the Ionic Revolt, by fugitives from Byzantium and Chalcedon.These statements may, however, be reconciled by supposing that the Thracian town was originally colonized by Megarians, and afterwards received additional colonists from Byzantium and Chalcedon.
