most numerous of his armies, six thousand horse, and thirty thousand foot, was instantly assembled; and his march from Salerno to Rome was animated by the public applause and the promise of the divine favor. Henry, invincible in sixty-six battles, trembled at his approach; recollected some indispensable affairs that required his presence in Lombardy; exhorted the Romans to persevere in their allegiance; and hastily retreated three days before the entrance of the Normans. In less than three years, the son of Tancred of Hauteville enjoyed the glory of delivering the pope, and of compelling the two emperors, of the East and West, to fly before his victorious arms. But the triumph of Robert was clouded by the calamities of Rome. By the aid of the friends of Gregory, the walls had been perforated or scaled; but the Imperial faction was still powerful and active; on the third day, the people rose in a furious tumult; and a hasty word of the conqueror, in his defence or revenge, was the signal of fire and pillage. The Saracens of Sicily, the subjects of Roger, and auxiliaries of his brother, embraced this fair occasion of rifling and profaning the holy city of the Christians: many thousands of the citizens, in the sight, and by the allies, of their spiritual father were exposed to violation, captivity, or death; and a spacious quarter of the city, from the Lateran to the Coliseum, was consumed by the flames, and devoted to perpetual solitude. From a city, where he was now hated, and might be no longer feared, Gregory retired to end his days in the palace of Salerno. The artful pontiff might flatter the vanity of Guiscard with the hope of a Roman or Imperial crown; but this dangerous measure, which would have inflamed the ambition of the Norman, must forever have alienated the most faithful princes of Germany.

The deliverer and scourge of Rome might have indulged himself in a season of repose; but in the same year of the flight of the German emperor, the indefatigable Robert resumed the design of his eastern conquests. The zeal or gratitude of Gregory had promised to his valor the kingdoms of Greece and Asia; his troops were assembled in arms, flushed with success, and eager for action. Their numbers, in the language of Homer, are compared by Anna to a swarm of bees; yet the utmost and moderate limits of the powers of Guiscard have been already defined; they were contained on this second occasion in one hundred and twenty vessels; and as the season was far advanced, the harbor of Brundusium was preferred to the open road of Otranto. Alexius, apprehensive of a second attack, had assiduously labored to restore the naval forces of the empire; and obtained from the republic of Venice an important succor of thirty-six transports, fourteen galleys, and nine galiots or ships of extra-ordinary strength and magnitude. Their services were liberally paid by the license or monopoly of trade, a profitable gift of many shops and houses in the port of Constantinople, and a tribute to St. Mark, the more acceptable, as it was the produce of a tax on their rivals at Amalphi. By the union of the Greeks and Venetians, the Adriatic was covered with a hostile fleet; but their own neglect, or the vigilance of Robert, the change of a wind, or the shelter of a mist, opened a free passage; and the Norman troops were safely disembarked on the coast of Epirus. With twenty strong and well-appointed galleys, their intrepid duke immediately sought the enemy, and though more accustomed to fight on horseback, he trusted his own life, and the lives of his brother and two sons, to the event of a naval combat. The dominion of the sea was disputed in three engagements, in sight of the Isle of Corfu: in the two former, the skill and numbers of the allies were superior; but in the third, the Normans obtained a final and complete victory. The light brigantines of the Greeks were scattered in ignominious flight: the nine castles of the Venetians maintained a more obstinate conflict; seven were sunk, two were taken; two thousand five hundred captives implored in vain the mercy of the victor; and the daughter of Alexius deplores the loss of thirteen thousand of his subjects or allies. The want of experience had been supplied by the genius of Guiscard; and each evening, when he had sounded a retreat, he calmly explored the causes of his repulse, and invented new methods how to remedy his own defects, and to baffle the advantages of the enemy. The winter season suspended his progress: with the return of spring he again aspired to the conquest of Constantinople; but, instead of traversing the hills of Epirus, he turned his arms against Greece and the islands, where the spoils would repay the labor, and where the land and sea forces might pursue their joint operations with vigor and effect. But, in the Isle of Cephalonia, his projects were fatally blasted by an epidemical disease: Robert himself, in the seventieth year of his age, expired in his tent; and a suspicion of poison was imputed, by public rumor, to his wife, or to the Greek emperor. This premature death might allow a boundless scope for the imagination of his future exploits; and the event sufficiently declares, that the Norman greatness was founded on his life. Without the appearance of an enemy, a victorious army dispersed or retreated
