Fiolar (and anyone else): very interesting thread. I would recommend a thoroughly interesting read which is excellent historical and archaeological background."Facing the Ocean: the Atlantic and its peoples" by Barry Cunliffe.Oxford University Press 2001.ISBN 0-19-924019-1.Starts from the year dot...written by a professor of archaeology with a big knowledge of related history. Calls into question a great many things we all tend to takefor granted if we were brought up on the historical theories of 100 years ago.
