The Britanni in 218 B.C.

The Britanni — Celtic Tribes.

The Celtic peoples of the great island across the Ocean — a land of green downland and crowning hill-forts, lying beyond the very edge of the continental world. Dimly known to the traders of the south as the source of tin, it is a misted country of many peoples, half rumour and half report at this far remove from the Inner Sea.
