Hans–Wilhelm Rathjen (1928- ) is a retired German high school teacher. In 2004 he published a book which claimed that Atlantis had been a federation of the megalithic peoples of Western Europe. Following the lead of Jürgen Spanuth he locates a capital of this ‘empire’ in the vicinity of Helgoland with a second power centre in North Africa. My principal argument against this is that there is no evidence of writing being used by the megalithic cultures, an ability clearly recorded by Plato.

His book has 526 pages and has had enthusiastic reviews, unfortunately it is only available in German at present.
