Æ18 - Caracalla LEG III, Ρ S

Rhesaena sits on the Khabur River in what is now northeastern Syria, and its coinage under Caracalla reflects the city's strategic value during Rome's persistent push into Mesopotamia. The reverse type referencing Legio III Parthica is directly tied to that legion's permanent garrison in the region — Septimius Severus had raised it specifically for the Parthian campaigns and stationed it at Nisibis, keeping it as a fixture of Roman military presence in the east rather than rotating it back to the frontier pool.
