Before mentioning the latest historians of this period, I must notice a considerable number of accounts of travels, books which are closely connected with history. The Bohemians were great travellers in those days, and a considerable number of them have recorded their journeys and adventures. I have already referred to John of Lobkovic when dealing with his more celebrated brother Bohnslav,[129] and the travels of Žerotin and Rosenberg have also been already mentioned. Of other records of travel, it will be sufficient to mention those of Prefat, Vratislav, and Harant of Polžic. Ulrick Prefat of Vlkanov, a citizen of Prague, undertook in 1546 a journey to Venice and Palestine, of which he has left us an interesting account. His descriptions of the Holy Land are, however, inferior to those of Harant, written somewhat later. VENCESLAS VRATISLAV of Mitrovic, born (1576) of a Roman Catholic family, was educated by the Jesuits, and had from his earliest youth a strong desire to visit distant lands. When not yet eighteen years of age he obtained permission to join the staff of Baron Krekvic, whom the Emperor Rudolph was sending as ambassador to Constantinople. He has left us a record of his journey and imprisonment;[130] for the Turks of that period had little regard for international law and diplomatic privileges. Vratislav's book has a certain youthful grace and simplicity, and he was by no means devoid of the gift of observation. Vratislav, on his return to Bohemia, published in 1599 the description of his travels and adventures. He afterwards, not unnaturally, took part in several campaigns against his old enemies, the Turks. Educated by the Jesuits and a staunch Romanist, he was, of course, on the side of the Archduke Ferdinand during the Bohemian troubles of 1618 to 1620.
