The Foundation Date of Atlantis is rarely discussed by investigators since Plato, the primary source, offers little relevant dateable or debatable evidence. Frank Joseph speculates that a fourth millennium BC date is possible^{[108 p.9]}. Plato’s text focuses on the time of Atlantis’ destruction suggesting an unbelievable date of 9,600 BC, which is probably due to some manner of textual corruption. However, the ‘lunatic fringe’ led by Blavatsky often suggest millions of years since its foundation.
