Origins of the Celts
http://thetranslatorscafe.wordpress.com/2008/06/03/celts-are-from-spain-says-professor/”>An article I found recently questions the commonly-held belief that the original Celtic homeland was in central Europea around Hallstatt in what is now Switzerland.
In a theory based an extensive overview of the linguistic and archaeological evidence, Professor John Koch of the University of Wales Centre for Advanced Welsh and Celtic Studies proposes that a Celtic civilisation and culture first developed in the west of Europe in the Bronze Age rather than in central Europe.
Inscriptions found on the Iberian peninsula and dating from 800 BC to 400 BC are in a Celtic language, Professor Koch believes. The language is known as Tartessian and is believed to be the oldest written language in western Europe.
There is also an Irish legend in Do Suidigud Tellaich Temra (The Yellow Book of Lecan) about the origins of the Gaelic Celts – “We are born of the children of Mile, of Spain.”
