Tripura is the name of a triple city in Hindu mythology that was famed for its architecture and rich adornments. Its inhabitants are reputed to have become greedy over time and were destroyed by Shiva (Mahabharata, Bk7, Drona Parva, Sec.XI). The story is almost the same as that of Atlantis and its demise. Since 1997 until his death in 2005 the late Arysio Nunes dos Santos has championed the idea that Plato’s Atlantis narrative regarding a submerged civilisation had been borrowed from the east. He also linked Atlantis with Tripura(a).
2005 not only saw the death of dos Santos shortly after the publication of his theory in book form, while in Moscow, Sergey Teleguin had his book, Anatomy of a Myth, published in Russian, in which he also identified Tripura with Atlantis. An English translation of part of his book has now been provided by Teleguin(c).
R. Cedric Leonard has also linked Atlantis with Tripura, the capital of the island of Atala(b). However, Leonard has chosen the Azores as the most likely location for Atlantis and dos Santos opted for Sundaland, a large landmass, now partly submerged encompassing, among others, Thailand, the Philippines and Indonesia!
