The Ten Lost Tribes of Israel is a reference to the ten of the twelve tribes deported from the Kingdom of Israel after its conquest by Assyria in 722 BC.
The variety of identifications put forward for some or all of these groups is quite remarkable, ranging from the reasonable to the ridiculous. At one end of that spectrum the view “is that the “lost tribes of Israel” were never really lost. Many of the Jews who remained in the land after the Assyrian conquest re-united with Judah in the south (2 Chronicles 34:6–9). Assyria was later conquered by Babylon, who went on to invade the Southern Kingdom of Israel, deporting the two remaining tribes: Judah and Benjamin (2 Kings 25:21). Remnants of the northern tribes would have thus been part of the Babylonian deportations. Seventy years later, when King Cyrus allowed the Israelites to return to Israel (Ezra 1), many (from all twelve tribes) returned to Israel to rebuild their homeland.” (a)
At the other end is the entertaining idea that the Lost Tribes inhabit the interior of a Hollow Earth, which is defended by flying saucers!(b)
Nearly as extreme is the attempt to link the Lost Tribes and Atlantis, a combination that would not normally leap to mind. However, some have attempted to justify such a linkage in spite of the contradictions between Plato’s story and the details of this minority opinion.
This alleged relationship between Atlantis and Israel points out that the Biblical patriarch Jacob who had twelve sons, excluded two of them, Levi and Simeon. Jacob is then presented as having been Poseidon with the ten remaining sons ruling Atlantis. One of Jacob’s sons, Gad, is assumed to have been Gadeiros, one of the ten sons of Poseidon. After that, no further parallels are offered to connect Jacob’s other sons with the remainder of Poseidon’s offspring.
Fabricius (1668-1736) was a prolific German scholar credited with writing 128 books, some of which can be read online(a). He located Atlantis in the Holy Land, an idea popular with a number of writers of that period, such as Baër and Eurenius.
Claude-Mathieu Olivier (1701-1736) was a French theologian and lawyer from Marseilles, who published his Dissertation sur le Critias (Essay on the Critias) in 1726. In it he developed the rather daring theory that the ten kingdoms of Atlantis should be equated with the ten lost tribes of Israel and placed Atlantis in the Holy Land. His idea was a development of the suggestions of other writers of the period, such as Baër and Eurenius who also sought to link biblical history with that of Plato’s Atlantis.
