It came to pass in the year of Christ 1260, when Baldwin was reigning at Constantinople,{1} that Messer Nicolas Polo, the father of my lord Mark, and Messer Maffeo Polo, the brother of Messer Nicolas, were at the said city of CONSTANTINOPLE, whither they had gone from Venice with their merchants’ wares. Now these two Brethren, men singularly noble, wise, and provident, took counsel together to cross the GREATER SEA on a venture of trade; so they laid in a store of jewels and set forth from Constantinople, crossing the Sea to SOLDAIA.{2} NOTE 1.—Baldwin II. (de Courtenay), the last Latin Emperor of Constantinople, reigned from 1237 to 1261, when he was expelled by Michael Palaeologus. The date in the text is, as we see, that of the Brothers’ voyage across the Black Sea. It stands 1250 in all the chief texts. But the figure is certainly wrong. We shall see that, when the Brothers return to Venice in 1269, they find Mark, who, according to Ramusio’s version, was _born after their departure_, a lad of fifteen. Hence, if we rely on Ramusio, they must have left Venice about 1253–54. And we shall see also that they reached the Volga in 1261. Hence their start from Constantinople may well have occurred in 1260, and this I have adopted as the most probable correction. Where they spent the interval between 1254 (if they really left Venice so early) and 1260, nowhere appears. But as their brother, Mark the Elder, in his Will styles himself “_whilom of Constantinople_,” their headquarters were probably there.

Thus Chaucer:— “In the GRETE SEE, At many a noble Armee hadde he be.” The term Black Sea (_Mare Maurum_ v. _Nigrum_) was, however, in use, and Abulfeda says it was general in his day. That name has been alleged to appear as early as the 10th century, in the form Σκοτεινή, “The Dark Sea”; but an examination of the passage cited, from Constantine Porphyrogenitus, shows that it refers rather to the Baltic, whilst that author elsewhere calls the Euxine simply Pontus.
