The Indus Valley civilisation has recently received a number of nominations as the original source of the Atlantis story. Dr. Ashok Malhotra has identified the submergence of the city of Dwarka as the inspiration for the story, which was then brought to Sumeria and later Egypt before transmission to Greece.

However, Radek Brychta has opted^[203] for ancient city of Dholavira as a more likely candidate, while independently Yashwant Koak arrived at the same conclusion and intends to publish soon.

A curious discovery in the central Indus city of Mohenjo-Daro was that 10% of artifacts discovered there related to play. Clusters of game pieces suggested the use of communal social centres.  Unrelated, but perhaps more relevant to our study is the fact that there is a dearth of weaponry fortifications or evidence of warfare in the Indus culture^(d), which is in sharp contrast to the belligerent Atlantean society described by Plato.

A comprehensive website^(a) with many photos and diagrams relating to the Indus Valley civilisation is available. A related article by Patrick Chouinard is also of interest^(b).

A recent discovery off the Konkan Coast in the State of Maharashtra in western India has revealed a remarkable structure that based on sea level changes may be 8,000 years old^(c). A wall 24km long, 2.7 metres high and 2.5 metres in width was discovered in just three metres of water. Speculation has centred on the possibility of it being evidence of a completely unknown civilisation that could pre-date that of the Indus Valley.
