It is obvious, that Haitho here describes that part of the empire of the Mongals which was subject to Baatu-khan. The Euxine or Black Sea, he calls the Great Sea. The sea of Tenue is that of Tanna or Azof, the town at the mouth of the Tanais or Don having been known by both of these names, the former evidently derived from the ancient name of the river, or the river from the town, and of which the modern name Don is a mere corruption. The empire of Kaffia is obviously that of Kiow, Kiovia, or Kiavia, long the capital of the Russian empire, and the residence of the czars or great dukes.—Forst.
Sec. 6. Beyond the great mountain of Belgian or Bilkhan, the Tartars lived formerly without religion, or the knowledge of letters, being chiefly employed in tending their flocks; and were so far from warlike, that they readily submitted to pay tribute to any neighbouring prince who made the demand. All the tribes of the Tartars were known by the name of Mogles, Moguls or Mongals; and in process of time they increased so much, as to form seven populous independent nations. The first was called Tartar, after a province of that name, which was their original habitation; the second Tangot, Tangut, or Tongusians; the third Kunat; the fourth Jalair or Thalair; the fifth Sonich; the sixth Monghi; and the seventh Tabeth. Prompted by a vision and a command from God, the chiefs of these nations chose Changi or Zinghis to be their sovereign ruler or Great Khan; and we are told that when he came down from the mountains of Belgian, the sea withdrew nine feet, and made a way for him where there was none before.
