Istanbul is a bridge between Europe and Asia, the Black Sea and the Mediterranean, a position that endows it with one of the most unique and beautiful settings in the world. For, between the hills on the European and Asiatic shores flows the Bosphorus, the brightest gem in the diadem of nature. "This beautiful strait, sometimes spelled Bosporus and sometimes Bosphorus, was so called from the earliest ages by the ancients; from the mythology of 10, the mistress of Jupiter, having passed over it in the shape of a cow. It resembles the Dardanelles, in length, breadth, and current, and like it, is a narrow separation that divides Europe from Asia; but it has many features familiar to itself. Instead of being a solitary stream running between deserted shores, it is a body of water full of life and animation, winding its way through banks covered with palaces and villages, shaded with magnificent forest trees, presenting to the eye, at every mile, a new scene of crowded existence."
