Thus the Polish language is spoken by a population of about ten millions.[8] Like all living languages, it has different dialects, and is in one place spoken with greater purity than in another. As these varieties, however, are neither very striking nor have ever had an influence on literature, they do not concern us here. The ancient Polish language seems to have been very nearly related to the dialects of the Czekhes and the Sorabian Vendes. Although very little is known in respect to the circumstances and progress of the formation of the language into its present state, it is sufficiently obvious, that it has been developed from the conflict of its natural elements with the Latin and German idioms. Of the other Slavic dialects, the Bohemian is the only one which has exerted any influence upon the Polish tongue. The Italian and Turkish words introduced during the dominion of an Italian priesthood, and through the political relations of the Poles and the Turks, never entered deeply into the body of the language; and might be easily exchanged for better Polish forms of expression. Of all the Slavic dialects, the Polish presents to the foreigner the most difficulties; partly on account of the great variety and nicety of shades in the pronunciation of the vowels, and from the combination of consonants in such a way that only a Slavic tongue can conquer them, and cause the apparent harshness in some measure to disappear;[9] partly on account of its refined and artificial grammatical structure. In this latter respect it differs materially from the Russian language; which, although equally rich, is remarkable for its simplicity and perspicuity. The Polish and Bohemian idioms, in the opinion of the best judges, are above all others capable of faithfully imitating the refinements of the classical languages; and the Polish prose is modelled after the Latin with a perfection, which, in the golden age of Polish literature, was one of its characteristic features. It is therefore surprising, that the Polish language in poetry, although in other respects highly cultivated, does not admit the introduction of the classical prosody. We mean, the Polish language in its present state; for it is very probable, that in its original character it possessed, in common with all the other Slavic languages, the elements of a regular system of _long_ and _short_ syllables. So long, however, as there have existed Polish poets, they have not measured, but, in imitation of the French, have _counted_ the syllables. With the exception of a few recent poets, who have written in blank verse, and a few weak attempts to adapt the Greek principles of accent to the Polish language, all Polish poetry is, like the French, in rhyme; and the French Alexandrine is the favourite form of the Polish poets.[10] FIRST PERIOD. _From the introduction of Christianity to Casimir the Great, A.D. 1333._
