Assarion - Septimius Severus and Caracalla

Carrhae — modern Harran in southeastern Turkey — was the site of Rome's catastrophic defeat against Parthia in 53 BC, where Crassus lost seven legions and his life. The city retained symbolic weight for the Severan dynasty: Septimius Severus campaigned repeatedly against Parthia, and Caracalla was murdered near Carrhae in 217 AD while relieving himself on the road to the temple of the Moon god the city was famous for. Local bronze issues featuring both emperors together were struck during the years of their nominal co-rule, though the political fiction of shared power barely survived Septimius's death. The absence of BMC and SNG Copenhagen references suggests surviving examples are poorly documented at best.
