Diamantis Pastras, a Greek-Australian confectioner, presented to the Atlantis Conference in 2005 his theory that Atlantis had been situated in the Cyclades and Astipalea in the Dodecanese, which he maintains was a larger landmass 3,500 years ago. He bases his theory on an ancient map from the Egyptian Book of the Dead in the British Museum.

Pastras has submitted another paper to the 2008 Atlantis Conference in Athens.
