Eight thousand years ago, the Black Sea was a freshwater lake, its waters flowing down to the Mediterranean via the Bosporus. Then an ice shelf in Antarctica suddenly collapsed and melted, and the flow of water abruptly and catastrophically changed direction. The Black Sea became brackish, and much larger, expanding to the north and west at the rate of a mile a day. Scientists believe that the cataclysmic displacement of water led to the cataclysmic displacement of people, and out of the chaos, agricultural was born. It is also thought that the Black Sea deluge was the historical basis for the ancient flood myths.-
-The Black Sea is indeed dark in color, but the name derives from the old Turkic scheme of applying colors to the cardinal directions. (White is west, Blue is east, Black is north, Red is south—hence Red Sea.) It was the center of the universe to the people who lived in that corner of the world. And now, with Russia’s invasion of Ukraine, the Black Sea is once again in the middle of everything.-
