Swedish scientist Ulf Erlingsso's book will be published next month: Atlantis from a Geographer's Perspective: Mapping the Fairy Land.

Just like Atlantis, Ireland is 300 miles (480 kilometres) long, 200 miles wide, and widest across the middle. They both have a central plain surrounded by mountains. Dr Erlingsson believes the idea that Atlantis sank came from the fate of Dogger Bank, an isolated shoal in the North Sea about 100 kilometres off the north-eastern coast of England, which sank after being hit by a huge floodwave around 6100BC.
