policy, and in the formation of great and advantageous alliances, we must refuse him, upon his advocate’s own showing, the merit of able internal administration. His military virtues are less questionable, although the greatest of his victories, which placed his rival in his power and secured his seat on the Neapolitan throne, was due less to any generalship of his own than to the bold stratagem of a gray-headed crusader. Apart from its historical importance, M. de St Priest’s work is valuable as exposing and illustrating the peculiar ideas, strange customs, and barbarous prejudices of a remote and highly interesting period, less known than it deserves, and whose annals and archives few have explored more industriously than himself. In this point of view are we disposed, whilst glancing at some of the principal events it records, especially to consider it; and under this aspect it will probably be most prized and esteemed by the majority. A greater familiarity than the general mass of readers possess with the complicated history of the second period of the middle ages is requisite for the due appreciation of the book, and especially of its first volume. This is purely introductory to the conquest. The name of the conqueror is mentioned for the first time upon its last page. The matter it contains is not the less essential. It sketches the establishment of the Norman dynasty in Sicily; the elevation of that country into a monarchy by Duke Roger II.; the fall of the family of Tancred, and the reign of Frederick II., (Emperor of Germany, and grandson of Barbarossa,) who inherited the crown of the Two Sicilies in right of his mother, the posthumous daughter of Roger, and the last of the Norman line. This brings us into the thick of the long-standing feud between the Pope and the Empire, which, after having had the whole of Europe for its battle-field, at last concentrated itself in a single country. “Towards the middle of the thirteenth century it was transported to the southern extremity of Italy, to the rich and beautiful lands now composing the kingdom of Naples. The quarrel of the investitures terminated by the crusade of Sicily; a debate about ecclesiastical jurisdiction ended in a dispute concerning territorial possession. But although reduced to less vast proportions and more simple terms, the antagonism of the pontificate and the throne lost nothing of its depth, activity, and strength. Far from becoming weakened, it assumed the more implacable and rancorous character of a personal encounter. The war became a duel. It was natural that this should happen. So soon as a regular power was founded in the south of Italy, Rome could not permit the same power to establish itself in the north of the peninsula. The interest of the temporal existence of the popedom, the geographical position of the States of the Church, rendered this policy stringent. The Popes could never allow Lombardy and the Two Sicilies to be united under one sceptre.
