Origin of the Atlantis Narrative *
The Origin of the Atlantis Narrative is declared by Plato to have been Egyptian as it was brought to Athens from Egypt by Solon. This is the almost universally accepted provenance of the story. However, other suggestions have emerged from time to time.
Another even more exotic claim(a) is that Plato’s Atlantis story was a reworking of the destruction of Lankapura as recorded in the Ramayana(b), one of the two great Hindu epic poems.
