It is, however, to four men belonging to a time somewhat subsequent to that of Dobrovsky that the revival of the language and literature of Bohemia is mainly due. They are Jungmann, Kolar, Safarik and Palacky. Joseph Jungmann (1773-1847) published early in life numerous Bohemian translations of German and English writers. His most important works are his _Dejepes literatury ceska_ (history of Bohemian literature), and his monumental German and Bohemian dictionary, which largely contributed to the development of the Bohemian language. John Kolar (1793-1852) was the greatest poet of the Bohemian revival, and it is only in quite recent days that Bohemian poetry has risen to a higher level. Kolar's principal poem is the _Slavy dcera_ (daughter of Slavia), a personification of the Slavic race. Its principal importance at the present time consists rather in the part it played in the revival of Bohemian literature than in its artistic value. Kolar's other works are mostly philological studies. Paul Joseph Safarik (1795-1861) was a very fruitful writer. His _Starozitnosti Slovanske_ (Slavic antiquities), an attempt to record the then almost unknown history and literature of the early Slavs, has still considerable value. Francis Palacky (1798-1876) is undoubtedly the greatest of Bohemian historians. Among his many works his history of Bohemia from the earliest period to the year 1526 is the most important. Other Bohemian writers whose work belongs mainly to the earlier part of the 19th century are the poets Francis Ladislav Celakovsky, author of the _Ruze stolistova_ (the hundred-leaved rose), Erben, Macha, Tyl, to mention but a few of the most famous writers. The talented writer Karel Havlicek, the founder of Bohemian journalism, deserves special notice.
