A Brief History of the Roman Denarius

For nearly five hundred years the denarius was the silver coin of Rome — the everyday money of soldiers, merchants and citizens from Britain to Syria. Small enough to hold in the palm, it is one of the most direct surviving links to the Roman world.

From Republic to Empire

The denarius was introduced during the Roman Republic, around 211 BC, and quickly became the backbone of Roman currency. Under the emperors it carried the ruler's portrait into every corner of the empire, a pocket-sized instrument of propaganda as much as trade.

What a denarius shows

A typical denarius bears the emperor's head and titles on one side and, on the reverse, a deity, personification or monument — Victory, Roma, a temple, a military standard. Each was a small political message, broadcast across the provinces mapped by the likes of d'Anville.

Debasement and decline

Over the centuries successive emperors reduced the silver content to fund wars and spending, until the denarius was silver in name only — a slow debasement that mirrored the strains on the empire itself.
