This coin is a silver Greek Stater minted in Corinth, circa 375-300 BCE. The obverse shows Pegasus in flight and the reverse depicts the head of Athena in profile wearing a Corinthian helmet with a dove in a wreath to the right.
In classical times, Corinth was a rich and quite powerful city and seaport on the narrow isthmus that joins the Peloponnese with the rest of Greece. Like most Hellenic city-states, Corinth produced its own distinctive coins. In Greek mythology, Pegasus, son of Poseidon, was born from the neck of Medusa when she was killed by the hero Perseus. In legend, Bellerophon, who became king of Corinth, tamed Pegasus with the aid of a golden bridle given to him by the goddess Athena. Athena is the goddess of war, handicraft, and practical reason.
