The two biographies convey a vivid impression of the court life (for it can hardly be otherwise described) of the great Bohemian nobles during the period that preceded the battle of the White Mountain. It is true that the position of the Lords of Rosenberg, the first of the Bohemian nobles, was a somewhat exceptional one. This appears very clearly from the letters, published by Březan, which were interchanged between the members of the imperial family and the Lords of Rosenberg. Of the two biographies, that of William of Rosenberg, the less interesting of the two brothers, is the more valuable one. William held several important appointments under the Imperial Government, and Březan gives a very clear outline of his official career. Very interesting are Březan's notes, which refer to the proposed election of Lord William to the Polish throne. He tells us that "the Lord of Rosenberg had then many adherents among the Polish nobles, more indeed than the House of Austria; and I do not say this to harm or disparage that illustrious House." Březan further tells us that "the Poles, after they had thus been mocked (by the flight of their king, Henry of Valois), searched for a new king. Some favoured the House of Habsburg, others desired Lord William as king, particularly as he was a descendant of the ancient family of the Orsinis, as by his ancestry, several centuries back, he was a Bohemian, and therefore belonged to a cognate country; also because he was a sensible, learned, temperate, Catholic noble." The election of Stephen Bathory to the Polish throne (1576) destroyed William of Rosenberg's hopes.
