Kollar's merit as a writer depends mainly on the "Daughter of Sláva," though he was a copious writer of prose as well as poetry. A small German pamphlet by Kollar entitled, _Ueber die literarische Wechselseitigkeit zwischen den verschiedenen Stämmen und Mundarten der Slavischen Nation_ ("On the Literary Solidarity of the various Branches of the Slav Nation"), which appeared in 1837, caused great sensation, and for a time acquired even political importance. In Bohemian Kollar wrote, besides his _Slávy Deera_, an account of his travels in Germany and Italy and several archaeological works. Of these, the _Staroitalia Slavjanská_ ("Slavic Ancient Italy"), written in the last year of Kollar's life, and dedicated to the Emperor Francis Joseph, is the largest. The author endeavoured, on the slightest evidence and by means of the most fantastical suppositions, to prove that a large part of the population of Italy--particularly in the north--is of Slav origin. Kollar is here constantly carried away by his exuberant imagination, and the book has no scientific value. It is, indeed, scarcely an exaggeration to call it a tissue of absurdities. Kollar's recently published correspondence with Jungmann, Šafařik, Palacký, and others has great interest. While Kollar devoted to the revival of the Bohemian language and literature his enthusiastic eloquence and poetic talents, Šafařik employed for the same purpose his vast erudition and unusual ability as a philologist. His works deal principally with the early origins of the Slav language and race, and of the early literature of Bohemia. The latter works were very valuable at a time when the Bohemian language was again acquiring the dignity of a written language. Like Jungmann, Šafařik also endeavoured to forward the advancement of his language by means of translations from more cultivated languages, and in his youth he also wrote poetry. But it is on his philological and archaeological works on the Slav race that his fame is principally founded. Equal to Dobrovský, and perhaps superior to Jungmann in erudition, some of his writings on these subjects are still standard works.
