The cimmerians, hittites, and thracians, are thought to have sailed the Black Sea during the bronze age, but where are the ruins of their ancient port settlements and cities? The noteworthy coastal ancient cities are greek, they began to explore and settle the current black sea coastline at the time of Jason and the Argonauts circa 1300 b.c., but no ruins of archaic port facilites and coastal buildings constructed more anciently by the cimmerians, hittites, nor thracians, so we should look offshore, to what the ex-soviet scientists have revealingly called the cimmerian shoreline, a hundred meters beneath the sea, the shoreline of what was a huge inland lake during the Ice Age, since submerged when the world ocean rose rapidly to enter the black sea basin when the Ice Age ended.
The cimmerians were also known as the gomera, the progeny of Gomer, son of Japheth, and the Askaniya National Park on the north shore of the Black Sea is the namesake of Ashkenaz, a son of Gomer, so coastal ruins of these patriarchs, and Heth (hittites), and Tiras (thracians) are predictably found on the old submerged cimmerian shoreline, ruins off Sinope, Turkey (hittites), and may off Bulgaria of the thracians, and a few off the north shore too, but how many more are down there, particulary at the submerged river mouths on the cimmerian shoreline?
The ancient russians knew the legendary black sea infilling as the flood of Dardan, who first sailed into the Black Sea, not having had to go up the river which is now the Dardanelles and Bosporus Strait, at around 1400 b.c, followed by Jason and the Argonauts, and soon thereafter, many more greek settlers who built the major port cities, ruins of which abound around the coastline of the Black Sea, with the older ones long since submerged, inundated when the Ice Age ended, known to the greeks as the Flood of Ogyges.
