Mopsium or Mopsion (Ancient Greek: Μόψιον) was a town and polis (city-state)[1] of Pelasgiotis in ancient Thessaly, situated upon a hill of the same name;[2] which, according to Livy, was situated midway between Larissa and the Vale of Tempe.
[3][4] Strabo relates that the origin of its name it was by a Lapith called Mopsus who traveled, according to Greek mythology, with the Argonauts in search of the Golden Fleece.
[2] Livy writes that during the Third Macedonian War, Mopsium was the scene of a battle between Romans and troops of Perseus of Macedon, which ended with a victory of the Romans.
Livy tells that the dead of the Macedonian troops had been about 8,000, the prisoners, 2,800, and the standards captured by the Romans, 27; while the Romans lost about 4,300 men and 5 standards.
[5] The city minted bronze coins in the 4th century BCE, with the legends «ΜΟΨΕΙΩΝ» and «ΜΟΨΕΑΤΩΝ».
