Aden was formerly a British possession and is now part of Yemen. Stan Deyo, author of The Vindicator Scrolls, in 1989 located Atlantis in Aden. A Dutch amateur Egyptologist, Alexander Muster, also promotes a similar idea through a variety of Internet forums. A former French police chief, Jacques Hébert, has proposed that the Yemeni island of Socotra was part of the Atlantean civilisation.
