Muscovy, which hath the name also of Russia the White, is a very large and spacious country, every way bounded with divers nations. Towards the south and east it is compassed with Tartaria, the northern side of it stretcheth to the Scythian Ocean; upon the west part border the Lappians, a rude and savage nation, living in woods, whose language is not known to any other people; next unto these, more towards the south, is Swecia, then Finlandia, then Livonia, and last of all Lithuania. This country of Muscovy hath also very many and great rivers in it, and is marsh ground in many places; and as for the rivers, the greatest and most famous amongst all the rest is that which the Russians in their own tongue call Volga, but others know it by the name of Rha. Next unto it in fame is Tanais, which they call Don, and the third Boristhenes, which at this day they call Dnieper. Two of these—to wit, Rha and Boristhenes—issuing both out of one fountain, run very far through the land: Rha receiving many other pleasant rivers into it, and running from the very head or spring of it towards the east, after many crooked turnings and windings, dischargeth itself and all the other waters and rivers that fall into it, by divers passages into the Caspian Sea. Tanais, springing from a fountain of great name in those parts, growing great near to his head, spreads itself at length very largely and makes a great lake; and then growing narrow again, doth so run for certain miles until it fall into another lake, which they call Ivan: and there hence, fetching a very crooked course, comes very near to the river Volga; but disdaining, as it were, the company of any other river, doth there turn itself again from Volga, and runs towards the south, and falls at last into the Lake of Moeotis. Boristhenes, which comes from the same head that Rha doth (as we said before), carrieth both itself, and other waters that are near unto it, towards the south, not refusing the mixture of other small rivers; and, running by many great and large countries, falls at last into Pontus Euxinus. Besides these rivers are also in Muscovy certain lakes and pools—the lakes breed fish by the celestial influence, and amongst them all the chiefest and most principal is called Belij Jesera, which is very famous by reason of a very strong tower built in it, wherein the kings of Muscovy reserve and repose their treasure in all time of war and danger.
