Flavius Josephus, the 1st century AD historian and Jewish priest, has been invoked by Georges Diaz-Montexano to support his belief in an Iberian location for Atlantis(a). Diaz-Montexano refers to Book II. 374-375, which records the incursion by, what appears to have been a tsunami, onto the Atlantic coastal lands of modern Spain and Portugal, while at the time occupied by the Lusitanians and Cantabrians. Diaz-Montexano claims, let it be said, without proof, that this could only have been the same inundation that destroyed Atlantis.
Ralph Ellis has made the wild claim that Josephus was in fact St. Paul!(b) This idea has been put forward by others(c).*On the other hand Flavio Barbiero offers the theory that Joserphus and St. Paul were certainly known to each other(d). In his book, The Secret Society of Moses , Barbiero expands on the idea that Josephus played an important role in the development of early Christianity.*
