Although old Saraï was depopulated by the plague in 1347–48, and new Saraï was destroyed by Timour, both cities recovered from those calamities, and in the later map of the world, by Fra Mauro, they appear near a tributary on the left bank of the Volga, but at a considerable distance from each other. The northernmost is known to the Russians as Great Saraï.
Previously to selecting old Saraï for his residence, the khan Barka was at Bolgar, the ancient capital of the kingdom of the Bolgars on the Volga, which had been subdued in 1236 by his brother and predecessor Batou, the “terrible Batou” of the Russians, surnamed by the Tatars, Saïn—The Good. An indigent Russian village stands on the site of the city, in the midst of ruins which impress the traveller by their extent; an impression I received when engaged in the Fourth Archæological Congress (1877), the members of which started upon their excursion from Kazan, and descending the river to Spassky-zaton, visited the locality distant seven miles in a direct line from the river. Considering the importance of these ruins, the large extent of ground they cover, the prodigious quantity of ancient oriental coins and other antiquities that are being continually recovered; considering, also, the testimony of Arabian authors and travellers on the commercial relations of the ancient Bolgars of the Volga, the question has frequently arisen—Why should that people have preferred to establish themselves at so great a distance from the river, after the manner of the inhabitants of the “city of the blind”, instead of selecting a more advantageous site? The enigma has been solved by Professor Golovkinsky (_Sur la formation permienne du bassin Kama-Volgien_, etc., in the _Mém. de la Soc. Minér. de St. Pétersbourg_, tom. i; and _Anciens débris de l’homme au Gouv^t. de Cazan_, in the _Travaux de la réunion des Natur. de Russie_, St. Pétersbourg, 1868), formerly of the University of Kazan, now Rector of that at Odessa. The distinguished geologist shows, that the Volga and the Kama have been subjected to great changes in their course above their junction; that to a comparatively recent period, the eastern bank of the bed where the two rivers united, was close to the height upon which is the village of Bolgar, and that this ancient bed is to be traced to an arm of the Kazanka called the Boulak, and to the lake Kaban, both of which flow through the city of Kazan, and through a partly dried up marsh near the said village.—BRUUN.
