With the introduction of Christianity, Russia, instead of entering into closer communion with the rest of the world, was separated from it even more securely than before, and soon after, an intellectual stagnation began that lasted very nearly to the end of the seventeenth century. Various causes combined to produce this singular effect. Chief of these was its geographical position. Living in the vast eastern plain of Europe, which in itself would have been productive of a larger life, the Russian tribes had civilised neighbours on one side only. On the north they were separated from the Swedes by rude Finnish tribes; on the south, they had for centuries to contend against all the nomads, Pechenyégs, Cumanians, Khazars, who slowly proceeded from Asia to central Europe to become lost in the nations to the south of the Carpathians and in the Balkan peninsula; in the east the Finns of the north met the Tartars of the south, and behind them lay unprofitable Asia. On the north-west, it is true, was the civilised Teutonic Order, but the inveterate hatred between these Germans and the Slavs prevented any intercommunication from that quarter. There was left Poland, through which Russia might issue into Europe; but savage Lithuania was wedged in between the two, so as to reduce still more the line of contact with the West. When Lithuania became civilised, and a part of Poland, the latter had grown suspicious of the youthful Ilyá of Múrom who “had sat thirty years upon the oven,” and enunciated a political maxim that either Russia would have to become Polish, or else Poland Russian. Knowing that there was no other exit for Russia, Poland permitted no light to reach it from the West. When England began to communicate with Russia in the sixteenth century, King Sigismund made an earnest appeal to Queen Elizabeth to stop sending skilled mechanics, lest the Colossus should awaken and become a danger to Europe.
