Theory that \'Celts\' are a myth

[Conal]

There are many puzzling aspects about celtic speakers in Britain. For example, the Brigantes, who we think spoke a celtic language, show a good deal of continuity from the Bronze age. Their neighbours in East Yorkshire however show a sudden change around 450BC. Whether this change was cultural or demic is something which is debated but it at least tells us that the 'celtic' Brigantes are older, in terms of archaeology, than the 'celtic' Parisii and that they don't fit into the old 'iron age' series of invasions model. It becomes a question, 'when did groups like the Brigantes enter Britain?'

And were the Brigantes of Britain related to those in Ireland?

Also there is a tribe named as Menapii in Ireland ... were these related to the Belgic tribe of the same name?
