I know not whether Sartach really believes in Christ, but am certain that he refuses to be called a Christian, and I rather think that he scoffs at Christianity. His residence lies in the way through which the Russians, Walachians, Bulgarians of the lesser Bulgaria, the Soldaians, or Christians of Casaria, the Kerkis, Alanians, and other Christians have to pass in their way with gifts or tribute to the court of his father Baatu-khan; and by this means Sartach is more connected with the Christians than any of the rest, yet when the Saracens or Mahometans bring their gifts, they are sooner dispatched. Sartach has always about him some Nestorian priests, who count their beads and sing their devotions. There is another commander under Baatu-khan, called Berta or Berca, who pastures his flocks towards the Iron-gate, or Derbent, through which lies the passage of all the Saracens or Mahometans who come from Persia and Turkey, to pay their gifts and tributes to Baatu, and who make presents to Berta in their way. This person professes himself to be of the Mahometan faith, and will not permit swines flesh to be eaten in his dominions. But it appearing to Baatu, that his affairs suffered detriment by this intercourse with the Mahometans, we learnt on our return, that he had commanded Berta to remove from the Iron-gate to the east side of the Volga. For the space of four days which we spent in the court of Sartach, we had no victuals allowed us, except once a little cosmos; and during our journey to the residence of his father Baatu, we travelled in great fear, on account of certain Russian, Hungarian, and Alanian servants of the Tartars, who often assemble secretly in the night, in troops of twenty or thirty together, and being armed with bows and arrows, murder and rob whoever they meet with, hiding themselves during the day. These men are always on horseback, and when their horses tire, they steal others from the ordinary pastures of the Tartars, and each man has generally one or two spare horses to serve as food in case of need. Our guide therefore was in great fear lest we might fall in with some of these stragglers. Besides this danger, we must have perished during this journey, if we had not fortunately carried some of our biscuit along with us. We at length reached the great river Etilia or Volga, which is four times the size of the Seine, and of great depth. This river rises in the north of Greater Bulgaria, and discharges itself into the Hircanian Sea, called the Caspian by Isidore, having the Caspian mountains and the land of Persia on the south, the mountains of Musihet, or of the Assassins on the east, which join the Caspian mountains, and on the north is the great desert now occupied by the Tartars, where formerly there dwelt certain people called Canglae, or Cangitae, and on that side it receives the Etilia, or Volga, which overflows in summer like the Nile in Egypt. On the west side of this sea
