Tetradrachm - Caracalla ΔΗΜΑΡΧ ΕΞ ΥΠΑ ΤΟ Δ

Caracalla arrived at Carrhae in 217 AD partly out of genuine religious devotion to the local moon god Sin, whose temple there drew his personal attention — and partly, it seems, to use the city as a staging ground for his planned Parthian campaign modeled on Alexander the Great. He never launched it. He was assassinated on the road between Carrhae and Edessa in April 217, killed by a soldier acting on orders from the prefect Macrinus. These provincial tetradrachms, struck across his final years, were produced in volume to pay troops concentrated in the region.
