@persagen Cool statue. But note that the "Celts" were not an indigenous people in Britain, but migrated there from the continent. They were pushed back into Scotland and Wales by the Romans.
In Scotland the Picts were around before the Celts arrived, and cohabited with them. No one knows where the Picts came from.
Keltoi was a name given by the Greeks to a tribe of people living in the south of France. It was not what they called themselves.
