This book presents evidence that an advanced civilization once existed in the area of the Atlantic Ocean in ancient times and, except for a few remnants, has since vanished due to cataclysmic activity. Spence does a compelling job in detailing the various myths and legends of the Aztecs, Brazilian Indians and the North American Indians, all in full support of the existence of Atlantis. The recent discovery of ancient underwater cities are causing renewed interest in Atlantis and the work of Spence.
