This coin is a Roman AR Double Victoriatus minted in Thessaly circa 44-40 BCE. The obverse depicts the laureate head of Zeus facing right and the reverse shows Athena Itonia advancing right with spear and shield.
the Thessalian League was loose confederation of Thessalian city states. After the Second Macedonian War (200-197 BCE), the victorious Roman general T. Quinctius Flamininus declared all of Greece “free”. Consequently, he reorganized the Thessalian League. It continued to exist even after Thessaly became part of the new Roman province of Macedonia in 146 BCE.
