In the year 965, the duke Miecislav married the Bohemian princess Dombrovka, and caused himself to be baptized. From that time onward, all the Polish princes and the greatest part of the nation became Christians. There is however not one among the Slavic nations, in which the influence Christianity must necessarily have exerted on its mental cultivation, is so little visible; while upon its language it exerted none at all. It has ever been and is still a favourite opinion of some Slavic philologists, that several of the Slavic nations must have possessed the art of writing long before their acquaintance with the Latin alphabet, or the invention of the Cyrillic system; and among the arguments by which they maintain this view, there are indeed some too striking to be wholly set aside. But neither from those early times, nor from the four or five centuries after the introduction of Christianity, does there remain any monument whatever of the Polish language; nay, with the exception of a few fragments without value, the most ancient document of that language extant is not older than the sixteenth century. Until that time the Latin idiom reigned exclusively in Poland. The teachers of Christianity in this country were for nearly five centuries foreigners, viz. Germans and Italians. Hence arose that unnatural neglect of the vernacular tongue, of which these were ignorant; the private influence of the German, still visible in the Polish language; and the unlimited dominion of the Latin. Slavic, Polish, and heathenish, were to them synonymous words. Thus, while the light of Christianity everywhere carried the first dawn of life into the night of Slavic antiquity, the early history of Poland affords more than any other part of the Christian world a melancholy proof, how the passions and blindness of men operated to counterbalance that holy influence. But although so unfavourably disposed towards the language, it cannot be said that the influence of the foreign clergy was in other respects injurious to the literary cultivation of the country. Benedictine monks founded in the beginning of the eleventh century the first Polish schools; and numerous convents of their own and other orders presented to the scholar an asylum, both when in the year 1241 the Mongols broke into the country, and also during the civil wars which were caused by the family dissensions of Pjast's successors. Several chronicles in Latin were written by Poles long before the history of the Polish literature begins; and Polish noblemen went to Paris, Bologna, and Prague, to study sciences, for the very elements of which their own language afforded them no means. Polish writers are in the habit of dividing the history of their language into five periods.[4] The _first_ period extends from the introduction of Christianity to Cassimir the Great, A.D. 1333. The _second_ period extends from A.D. 1333 to A.D. 1506, or the reign of Sigismund I.
