After Rome's victory in the First Punic War (241 BC), new Roman silver coins came into circulation. The city issued didrachms (double drachms) and drachms. The images on both denominations complemented each other: The didrachms show Jupiter in a four-horse chariot, swinging a bundle of thunderbolts; the chariot, driven by the goddess Victoria, is heading right. On the drachms, the two of them return from the opposite direction. The obverses of both denominations bore Janus, the double-headed god of beginnings and ends.
