History: This coin refers to the surrender to Augustus the standards which the Parthian's had taken from Crassus and his slaughtered legions. Mars, the god of war, is depicted here in reference to the temple which Augustus, on the restitution of the military ensigns by the Parthians, had built in the capital, and which he dedicated to Mars the Avenger. A triumphal arch honouring the event was also built in the year 20 BC.
