Battle of Carrhae

01Parthian horse archers carried enough arrows for sustained volleys — an unprecedented tactic that Roman shields and formation were useless against.
02Of 44,000 Roman soldiers at Carrhae, roughly 20,000 were killed, 10,000 captured, and only 10,000 escaped; seven eagle standards were lost.
03Crassus's severed head was delivered to the Parthian king during a performance of Euripides' Bacchae — used as the prop head of Pentheus.

Rome's richest man, Crassus, marched seven legions into Parthia in 53 BC and watched Parthian arrows destroy them all. His severed head was delivered to a banquet and used as a prop in a theatrical performance.
