This province of Casaria has the sea on three sides; on the west, where stands Kersova, or the city of St Clement; on the south, where is the city of Soldaia, at which we landed; and on the east, where Matriga is situated at the mouth of the Tanais. To the east of that mouth is the city of Zikia, and the countries of the Suevi and Hiberi still further east, all of which are not under the dominion of the Tartars. To the south is Trebisond, which has its own prince, named Guido, who, although of the imperial race of Constantinople, is under the Tartar dominion; and next to it is Synope, which belongs to the sultan of the Turks, who is likewise subjected to the Tartars. Beyond this is the country of Vastacius, whose son is named Astar, after his maternal grandfather, and this country is not under the dominion of the Tartars. From the mouth of the Tanais to the Danube, and even beyond the Danube towards Constantinople, including Walachia, which is the country of Assanus, and the lesser Bulgaria as far as Solonia, pay tribute to the Tartars, who of late years have exacted an axe from each family, and all the corn which they find in heaps, in addition to the regular tribute. We landed at Soldaia[5] on the 21st of May, where certain merchants of Constantinople had previously arrived, who reported that ambassadors from the Holy Land were coming thither, on their way to Sartach; although I had publickly declared on palm Sunday, in the church of St Sophia, that I was no ambassador from you or any one, and only travelled to these infidels, in conformity with the rule of our order. On our arrival, these merchants advised me to be cautious of what I said; for, as they had already reported that I was an ambassador, if I should now say the contrary, I should be refused a free passage. Upon this, I addressed myself to the lieutenants of the city, because the captains had gone with the tribute to Baatu, and were not yet returned: saying, "We have heard in the Holy Land, that your lord Sartach[6] had become a Christian, which hath greatly rejoiced all the Christians, and especially the most Christian King of the French, who is there in pilgrimage, fighting against the Saracens, that he may redeem the Holy Land out of their hands: Wherefore, I desire to go to Sartach, that I may carry him letters from the king my master, in which he gives him intelligence of importance to all Christendom." They received us graciously, and entertained us hospitably in the cathedral church; The bishop had been at the court of Sartach, and told me many good things concerning him, which I did not find afterwards to be true. They then gave us our choice, either to have carts drawn by oxen, for carrying our baggage, or sumpter horses; and the Constantinopolitan merchants advised me to purchase covered carts, like those in which the Russians carry their peltry, in which I should put every thing which was wanted for daily use;
