It is a natural and easy transition from Peter of Rosenberg to another great Bohemian nobleman, Charles of Žerotin, who indeed was often politically associated with Rosenberg, particularly during the contest between King Rudolph II. and his brother Matthew, which occurred in the early years of the seventeenth century. Žerotin was, it is true, a maker rather than a writer of history. On two occasions, in 1608 when Rudolph was contending with his treacherous younger brother Matthew, and in 1619, when Frederick of the Palatinate attempted to oust the house of Habsburg from the Bohemian throne, Žerotin's attitude to a great extent decided the fate of his country. Žerotin's numerous writings may also be considered materials for history rather than historical works. Yet no outline of Bohemian literature would be complete were the name of Žerotin omitted. CHARLES OF ŽEROTIN was born in 1564 at Brandeis, on the Adler, one of the Bohemian estates of his powerful family. Like many Bohemian noblemen of this period, Charles spent a considerable part of his youth in foreign countries, both as a student and as a soldier. At Genoa he fell under the influence of the Calvinist divine Theodore de Beza, but he never (as has been stated) abandoned for Calvinism the Church of the Bohemian Brethren, to which his family had belonged from the time that the Brotherhood had been founded. His writings as well as his political career prove that he was a faithful adherent of that community, of which he was one of the most illustrious members. In the year 1591 he took service under Henry IV. of France, whom all Protestants then recognised as their leader. Žerotin's correspondence, which is very extensive, is particularly interesting when he refers to this period of his life.[128] He appears to have felt very little sympathy for the French prince, to have distrusted him, and almost to have foreseen his conversion to the Church of Rome. Žerotin, whose motives were always disinterested and elevated though often unpractical, could not have felt much sympathy for an "opportunist." Žerotin's later life was spent almost entirely in Bohemia and Moravia, the countries where his ancestral estates were situated. He favoured the cause of the Archduke Matthew against King Rudolph in 1609, and in 1618 was one of the few Protestant noblemen who remained faithful to the House of Habsburg. As reward for his fidelity, he was allowed to remain in his country after the battle of the White Mountain, when most Protestants had already been expelled. He was even able to afford aid and shelter to many other members of the Brotherhood. Among these was Komenský. He sought refuge at Brandeis, and wrote there his _Labyrinth_ _of the World_, which was dedicated to Žerotin.
