In every _bilina_, and also in songs which celebrate the seed-time, the pagan feast of the summer solstice, and the spring-time, we notice the two characteristics of Russian thought,--a lively imagination and a dreamy sadness, which is most evident in the love-songs. On coming in contact with Christianity the pagan tale became a legend, and the clergy, brought from Byzantium by Valdimir the Baptizer, gave the people the Gospel in the Sclavonic tongue, translated by two Greek brothers, Cyril and Methodius, and the day of liturgical and sacred literature was at hand. The apostles of Christianity arranged the alphabet of thirty-eight letters, which represent all the sounds in the Sclav language, and founded also the grammar and rhetoric. As in every other part of Christendom, these early preachers were the first to enlighten the people, bringing ideas of culture entirely new to the barbarous Sclavonic tribes; and the poor monk, bent over his parchment, writing with a sharp-pointed reed, was the first educator of the nation. In the eleventh century the first Russian literary efforts began to take shape, being, like all early-written literature, of essentially clerical origin and character,--such as epistles, sermons, and moral exhortations. The chief writers of that time were the monk Nestor, the metropolitan Nicephorous, and Cyril the Golden-Mouthed, who imitated the florid Byzantine eloquence. At the side of ecclesiastical literature history was born; the lives of the saints prepared the ground for the chroniclers, and Nestor's Chronicle, the first book on Russian history, was written. The early essays in profane history, which took the form of fables and trenchant sayings disclosing a vein of satire, still smack of the ecclesiastical flavor, although they contain the instincts of a laic and civil literature. The people had their epic, the clergy accumulated their treasures, but the warriors and knights, who with the sovereign formed a separate society, must have their heroic cycle also; and bards and singers were found to give it to them in fragmentary pieces, among which the most celebrated is the "Song of the Host of Igor," which relates the victories of a prince over the savage tribes of the steppes. The poem is a mixture of pagan and Christian wonders, which is only natural, since in the twelfth century (the era of its composition) Christianity, while triumphant in fact, had not yet succeeded in driving out the old Sclavonic deities.
