He has set free the two seas meeting together. There is a barrier between them. They do not transgress. (Quran, 55:19-20)
But when the Quran speaks about the divider between fresh and salt water, it mentions the existence of “a forbidding partition” with the barrier. God has said in the Quran:
He is the one who has set free the two kinds of water, one sweet and palatable, and the other salty and bitter. And He has made between them a barrier and a forbidding partition. (Quran, 25:53)

It takes quite a bit of imagination (plagiarism) to connect the koran to the Black Mediterranean question...but that's islam for ya...
...I meant to write ‘Black Sea-Meditteranean’ ...

According to the Samothracian myth of the great flood, which is but a variation of the panhellenic myth of the Greek cataclysm, and the rescue of Deucalion and Pyrrha, it was here on Samothrace’s mountains that the Kaveiri were saved.
As witnessed by the findings near the present village of Karyotes, the island was inhabited in prehistoric times. Possibly during the Neolithic Era, certainly during the Bronze Age.
