Altho for many centuries separated from the Pontus by the nomad-haunted steppe-border, the Ukrainian [16]nation is closely identified with this sea. An enormous number of legends and songs of the Ukrainian people deal with it; even in fanciful love-songs it is mentioned. And the intimacy of this East European nation with the Sea need not surprise us. The Black Sea, with which so much in Ukrainian song and story is connected, has had a significance in the history of the Ukraine which has not been forgotten in the unwritten traditions of the people. How many cultural and warlike memories are connected with the Black Sea! How much Ukrainian blood has mingled with its waters! The Black Sea is not large (450,000 square kilometers). It is a landlocked sea, situated between Europe and Asia, and connected with the Mediterranean Sea by the narrow Straits of the Bosphorus and the Dardanelles and the Sea of Marmora, which, geologically speaking, is a basin formed by subsidence. Great subsidences of the earth’s surface created the deep basin of the Pontus. The Pontus was a part of the extensive upper Miocene and Sarmatian inland sea, which slightly flooded large districts of the present European continent as far as the Vienna basin. Toward the end of the tertiary period, this inland sea shrank and separated into single sea basins. The Pontian basin became connected with the Mediterranean Sea later, in the latter part of the diluvial period, by means of great subsidences of recent date. The present morphology of the Pontus is in full accord with this genesis. The northern part, as far as the line of communication between the Balkan and Yaila Mountains, is a shallow sea of a depth of less than 200 meters; the so-called bay of Odessa is barely 50 meters deep; the Sea of Azof, projecting to the northeast, barely 15 meters. But just on the southern border of the line of plicated mountains, which is broken at this point, the bottom of the Black Sea declines rapidly to greater depths (1500 meters) until, declining more gradually now, it attains the depth [17]of 2245 meters in the center of the oval-shaped main basin of the Pontus.
