Diobol

Eion was an Athenian-controlled emporion on the Strymon River in Thrace, a strategically vital staging post for Aegean trade and Macedonian frontier access. The city was taken by the Persians under Boeges during Xerxes' western campaign and held until 476 BC, when Cimon besieged it so relentlessly that Boeges burned his treasury, killed his family, and threw himself into the flames rather than surrender. Coinage from this narrow window — the years immediately following Athenian reoccupation — is exceptionally scarce by any measure.
