One of the most successful strokes of his policy, was his marriage with Sophia, daughter of the Emperor Paleologos, who had been driven from Constantinople by the Turks. This alliance, which he sought with great assiduity, not only added to the dignity of his government at home, but opened the way for an intercourse on equal terms with the greatest princes of Europe. It was Sophia who dissuaded him from submitting to the degrading ceremonial which had been observed on receiving the Tartar ambassadors at Moscow--and to her he probably owed the feelings of personal dignity which he evinced in the latter part of his reign. It was this alliance that at once placed the sovereigns of Russia at the head of the whole Greek church; whose dignitaries, driven from the stately dome of St Sophia in Byzantium, found shelter in the humbler temple raised by the piety of their predecessors, some ages before, in the wilds of Muscovy, and more than repaid the hospitality they received by diffusing a love of learning amongst a barbarous people. It was by means of the Greeks who followed Sophia, that Ivan was enabled to maintain a diplomatic intercourse with the other governments of Europe; it was from her that Russia received her imperial emblem, the double-headed eagle; it was in her train that science, taste, and refinement penetrated to Moscow; it was probably at her instigation that Ivan embellished his capital with the beauties of architecture, and encouraged men of science, and amongst others Antonio, "the heretic," and Fioraventi Aristotle, the architect and mechanician, to settle at Moscow. But it is time we should proceed to the story. The greater part of the first volume is occupied by an account of the family, birth, and youth of the hero. Born of a noble family in Bohemia, he is educated as a physician. This was not the voluntary act of his parents; for what haughty German baron of those times would have permitted his son to degrade himself by engaging in a profession which was then chiefly occupied by the accursed Jews? No, this was a degradation prepared for the house of Ehrenstein, by the undying revenge of a little Italian physician, whom the stalwart baron had pitched a few yards out of his way during a procession at Rome. This part of the history, though not devoid of interest, is hardly within the bounds of a reasonable probability--but it contains some passages of considerable vigour. The patient lying in wait of the revengeful Italian, and the eagerness with which he presses his advantage, making an act of mercy minister to the gratification of his passion, is not without merit, and will probably have its attractions for those who find pleasure in such conceptions.
