Březan's biography of Lord Peter of Rosenberg is a very disappointing book, if we consider that he was dealing with an intensely interesting subject. The semi-independent position of the great Bohemian nobles, who lived principally on their vast estates, surrounded by dependents and servants, free from the control of a court, and to a great extent even from the criticism of their equals, in some cases greatly developed their individuality. To no one does this apply to a greater extent than to Lord Peter of Rosenberg. The heir of the great family that had supplied so many leaders to the Romanist Church, Peter joined the community of the Bohemian Brethren, it is said through the influence of his wife, who belonged to that Church. Whether there is any connection between this change of creed and the scandalous stories which Catholic writers (whose works alone were known in Bohemia during two centuries) have circulated I do not wish to determine. They tell us that Lord Peter established a "harem" at his castle of Wittingau, to which the fairest women from all parts of Europe were conveyed. This is obviously an absurd exaggeration, though it is probable that Lord Peter had in his youth led an immoral life. With regard to the accusations of intemperance and of cruelty to his servants, it is probable that Peter of Rosenberg was in such matters neither better nor worse than the other great Bohemian nobles of his time.

Where he indeed differed from many of them was in his taste for literature and art. The Rosenbergs had at all times taken much interest in the archives of their family, and indeed preserved them so carefully that most of these documents are even now in a state of perfect preservation. Palacký, who examined them in the present century, witnesses to this, as well as to their great importance for the history of Bohemia, in which the Lords of Rosenberg played so large a part. Peter showed the same interest in the family archives as his predecessors. When selling one of his castles to the Emperor Rudolph II., he stipulated that he should retain possession of one thousand documents which he considered of historical value. In printed works also Lord Peter's interest was great. As early as in 1573, twenty years before he acceded to the family estates, Peter had collected 243 printed volumes. Březan, who had charge of Lord Peter's library, and was authorised to enlarge it, tells us that it was from this modest beginning that the far-famed Rosenberg library sprang. Many books were inherited from Lord William, and many purchased from monasteries and elsewhere. The library at last became a very extensive one. The Rosenberg library, in consequence of the events of the Thirty Years' War, eventually found its way to Stockholm, where Březan's catalogue of the library is also still preserved. Peter of Rosenberg is notable also as a patron of literature, and, among others, the poet Lomnický[127] enjoyed his protection for many years. Lomnický showed his gratitude by writing on the death of Peter of Rosenberg perhaps his one touching and heartfelt poem. That Peter was, like his brother, interested in alchemy, hardly requires mention, for almost all the great Bohemian nobles then followed the example of Rudolph, their sovereign, who delighted in the study of alchemy.

Peter's interest in music was also very great. Even before inheriting Wittingau from his brother William, he had established a small orchestra at Běychin, and he afterwards devoted much time and expense to the improvement and aggrandisement of the magnificent orchestra which Lord William had founded at Wittingau. Březan, in his biographies of both brothers, gives an interesting account of the cultivation of music in Bohemia in the sixteenth and the beginning of the seventeenth century. Lord Peter also undoubtedly showed a considerable amount of interest in other arts. In Březan's biography, written in chronological order, we read under "December 19, 1598.—The Lord of Hradec sent our sovereign lord (Lord Peter) eighteen pretty painted figures, very poetical, and representing Venus."

In Bohemian politics Peter of Rosenberg played a very important part, and his change of creed appeared as an event of the greatest importance on the ever-varying stage of Bohemian political life. Peter of Rosenberg was on terms of intimacy with Christian of Anhalt, perhaps the greatest statesman of the seventeenth century. He acted as Anhalt's representative in Bohemia, and was no doubt initiated into his far-reaching plans. Anhalt, as recent research has sufficiently proved, intended to use the dissensions between Rudolph and his brother Matthew for the purpose of totally destroying the power of the House of Habsburg. On these and similar subjects of the greatest interest Březan has little or no information to give, and his biography, as already stated, is disappointing.

The book, written in chronological order, contains accounts of Lord Peter's travels, but here, too, a mere outline of the occurrences is given. When mentioning Peter's journey to England, Březan merely tells us (under February 1563) that "after Lord Peter had been received in England with Christian kindness by her royal majesty Queen Elizabeth, and had then been kindly and graciously dismissed, her majesty was graciously pleased to grant him a royal decree addressed to all her officials and to those of all the towns." Březan then gives the full wording of this passport, if we may thus call it, in which Lord Peter is described as "one of the chamberlains of our good brother the King of the Romans."

Březan devotes much space to detailed accounts of the domestic arrangements at the castle of Wittingau, and his book is a treasury for those who would study the social condition of Bohemia at this period. Březan's style has little grace, partly no doubt in consequence of the chronological form which he has given to his book. The following portrait of Lord Peter of Rosenberg is a characteristic specimen of Březan's style: "Lord Peter's motto was 'In silentio et in spe.' It should be mentioned that this lord, for the purpose of living wisely, prudently, and in a way that beseems a Christian, and also that he might constantly remember death, always had a death's head placed on a board over the table in his apartment. He even founded an association, the device of which was a golden death's-head of the value of eight ducats. This badge he himself usually wore round his neck. It had on one side the inscription, 'Memento mori,' and on the other, 'Cogita æternitatem.' And this order he distributed among his friends, both lords and ladies, and he ordered me to keep a special register, where the names of these persons were entered."

"He was a nobleman of well-shaped figure, and more refined than his brother William. His features were charming, his manners dignified and truly princely, his speech was sensible, he was compassionate and affable, and though he was sometimes angry, whenever he had scolded or cursed some one he always afterwards excused himself with mild words. He was a gay and jocose nobleman, though in his old age he gave himself up entirely to piety, read religious books with pleasure, and listened eagerly to the word of God. He was keen for all novelties, a lover of all sciences and arts, and he spent large sums on them. He had a special fancy and predilection for building, and in this resembled his brother William. He was in the habit of standing oftener than sitting, and of walking constantly, and so quickly that it was difficult even for young men to keep up with him. By a bequest in his will he provided for the maids of the woman-apartments, and freed them (from bondage), ordering that each should receive a sum of gold as a present; and as trustees for this bequest he appointed Albert Pauzar of Michnic and Volesná, Henry Caslav of Podol, and Frederick Frokštejn of Naceslavic, his servants and courtiers."

"He was a very valorous nobleman, courageous and even somewhat venturesome; for he boldly approached wild beasts, bears, wolves, horses, and dogs without feeling any fear. And, on the whole, I do not know that anything was wanting in this heroic personage, except that which he himself deplored on his death-bed, that he had not sufficiently cultivated the study of literature."

Peter of Rosenberg died in 1611, only a few years before the momentous events which so completely changed the destinies of his country.
