Of Balbin's many works we may mention the _Miscellanea_, a vast compilation into which he admitted writings of earlier authors; the _Epitome Rerum Bohemicarum_, his most valuable work; the _Bohemia Docta_; and a curious work in defence of the Bohemian language entitled _Disertatio Apologetica Linguæ Slovenicæ_. The difficulties which Balbin encountered when he attempted to publish his works have already been alluded to. Great objections were raised, in particular, against the _Epitome Rerum Bohemicarum_; but after long negotiations, influential friends of Balbin induced the Emperor Leopold I. in 1677 to give his consent to the publication of the book. The _Disertatio Apologetica_, on the other hand, was totally condemned by the Austrian authorities, and was, indeed, only published a century after the author's death. Another Catholic priest whose historical labours were valuable for his country was Tomas Pešina, who was ennobled and granted the title of Cechorod (born 1629, died 1680). The Latin works of Pešina, who was a friend of Balbin, treat principally of Moravia, and are still of interest. To the eighteenth century belong the German works of Joseph Bienenberg, which deal with the archaeology of Bohemia. In 1778 Bienenberg published his _Alterthümer in Königreiche Böhmen_, and two years later his _History of the Town of Königgrätz_. The latter work has a far wider interest than its name suggests. Bienenberg gives many interesting details concerning Zižka's wars, and he prints the celebrated "Articles of war" of the great Bohemian general. The fact that these and other writers who sympathised with the Bohemian people yet wrote in foreign languages, proves how deep the national language had sunk. Become little more than an idiom used by the peasantry in some parts of Bohemia, it was no longer available for literature of a more elevated character.
