This Roman denarius from the year 42 BC shows Minerva, the goddess of war. She wears a helmet and an Aegis, a fearsome goatskin that she used to let it storm: When she shook the skin it sent out thunderbolts, thunder and darkness.
The reverse shows Hercules, the strongest man of Antiquity and the invincible hero of the Greek legend, with a club and a lion's skin.
With these images the moneyer C. Vibius Varus made propaganda for the war that Rome was preparing in 42 BC. It was a conflict of Roman against Roman – of the Republicans, the assassins of Julius Caesar who had aimed for autocracy and for that reason been killed (44 BC), and of the followers of Ceasar's successors, the Triumviri Octavian (the later Emperor Augustus), Marcus Antonius and Marcus Aemilius Lepidus.
