For eight years beginning in 58 BC, the Roman general Julius Caesar waged war on the peoples of Gaul. In the Gallic Wars, Celtic, Germanic, and Britonic tribes fought to defend their homelands against Roman incursion. A united front may well have defeated Rome, stopping Caesar, and changing the course of history. But the squabbling tribes could not overcome internal divisions, and Caesar played them off each other. By the time the Gallic chieftain Vercingetorix gathered the Gauls under a single banner, it was too late. Gaul fell to the Romans.-This is a genuine silver Celtic quinarius struck during the first century BC. On the obverse is a Celtic imitation of the goddess Roma, common on Roman coins of the period. The reverse shows a stylized horse.
