Politics, too, united with religion. Stibor of Cimburg, a patriotic and distinguished nobleman, wrote in 1467 an ingenious work in the form of a novel, "On the goods of the Clergy;" Waleczowsky wrote on the vices and hypocrisy of the clergy; and Zidek, in 1471, instructions on government. All these books were dedicated to king George, and the latter work was even written at his instigation. Hagck of Hodielin, and Wlezek, between 1413 and 1457, wrote strategetical works. Marco Polo's description of the East, and Mandeville's Travels, were translated from the Latin. Kabatnik, J. Lobkowicz, and Bakalarz, wrote descriptions of Palestine between 1490 and 1500; the two first in books of travels. Mezyhor wrote a journal of the travels of Lew of Rozhmital, whom he accompanied as jester through Europe and a part of Asia. Collections of statutes, of the decrees of diets, of judicial decisions, and of other documents, were made by patriotic and sometimes eminent men; and those merely extant in Latin were carefully translated into Bohemian.[25] Thus they gathered materials for future historians, although in their own day the field of history was but poorly cultivated, or at least with no more than common ability; for, as to quantity, there is no want. Procopius, following out the example of Dalimil, wrote a new rhymed chronicle; Bartosh of Drahenicz wrote a chronicle extending from 1419 to 1443, in barbarous Latin, to which he added some notes in Bohemian. Several other chronicles, the authors of which are not known, serve as continuations of those of the preceding century, which were devoted to the affairs of their own country. The above-mentioned Zidck, on the other hand, undertook to write a universal history, after the division of time then customary, into six ages. This book forms the third part of his great work, "Instructions on Government," to which we have above alluded. In this work the author seizes every opportunity to lecture the king, to give him advice, and to rebuke him. According to Dobrovsky, his boldness not unfrequently degenerates into coarseness and insolence. It is an amusing reproach, which among others he brings against the king, that he had net one camel, whilst Job had six thousand. The same individual wrote also a large work in Latin, a kind of Cyclopædia, the manuscript of which is in the library of the university of Cracow. We finish the history of this period with a short account of the state of medicine and natural sciences in Bohemia. It is true, that the greater part of the learned men who wrote on these subjects, preferred the use of the Latin language. But many of them were in the habit of making at least Bohemian extracts or abridgments of their most popular works, or sometimes had the whole of them translated by their pupils. Among the medical writers of this time, Christian Prachatitzky a clergyman, John Czerny and Claudian Bohemian brethren, Albik, and Gallus, must be mentioned; the two latter wrote only in Latin.
