The Celts
In Britain and elsewhere, a number of Celtic tribes issues coins in gold, silver, potin, and base metals. The Celts were here before the Romans, some became assimilated into Roman civilisation, others moved or were defeated. It is often stated that they left no written records, but this is inaccurate as some of their coins were inscribed. Please see the magnificent Celtic stater in our photograph. It bears the inscription "CUNO" an abbreviation for Cunobelin, a chieftain of the Catuvellauni tribe. It constitutes a written record, as do all the other inscribed Celtic coins, however most Celtic coins are unfortunately uninscribed. They also clearly show that the Celts used written language, even if other evidence is not extant.
We feel tempted to add the joke that Cunobelin invented his own language which was named after him, although we cannot remember the name of the language, it is on the tip of our tongue!
