The History of the Decline and Fall of the Roman Empire - Edward Gibbon [1903]
Chapter LVI: The Saracens, The Franks And The Normans.
Part IV.
Of the Latin princes, the allies of Alexius and enemies of Robert, the most prompt and powerful was Henry the Third or Fourth, king of Germany and Italy, and future emperor of the West. The epistle of the Greek monarch ^81 to his brother is filled with the warmest professions of friendship, and the most lively desire of strengthening their alliance by every public and private tie. He congratulates Henry on his success in a just and pious war; and complains that the prosperity of his own empire is disturbed by the audacious enterprises of the Norman Robert. The lists of his presents expresses the manners of the age - a radiated crown of gold, a cross set with pearls to hang on the breast, a case of relics, with the names and titles of the saints, a vase of crystal, a vase of sardonyx, some balm, most probably of Mecca, and one hundred pieces of purple. To these he added a more solid present, of one hundred and forty-four thousand Byzantines of gold, with a further assurance of two hundred and sixteen thousand, so soon as Henry should have entered in arms the Apulian territories, and confirmed by an oath the league against the common enemy. The German, ^82 who was already in Lombardy at the head of an army and a faction, accepted these liberal offers, and marched towards the south: his speed was checked by the sound of the battle of Durazzo; but the influence of his arms, or name, in the hasty return of Robert, was a full equivalent for the Grecian bribe. Henry was the severe adversary of the Normans, the allies and vassals of Gregory the Seventh, his implacable foe. The long quarrel of the throne and mitre had been recently kindled by the zeal and ambition of that haughty priest: ^83 the king and the pope had degraded each other; and each had seated a rival on the temporal or spiritual throne of his antagonist. After the defeat and death of his Swabian rebel, Henry descended into Italy, to assume the Imperial crown, and to drive from the Vatican the tyrant of the church. ^84 But the Roman people adhered to the cause of Gregory: their resolution was fortified by supplies of men and money from Apulia; and the city was thrice ineffectually besieged by the king of Germany. In the fourth year he corrupted, as it is said, with Byzantine gold, the nobles of Rome, whose estates and castles had been ruined by the war. The gates, the bridges, and fifty hostages, were delivered into his hands: the anti-pope, Clement the Third, was consecrated in the Lateran: the grateful pontiff crowned his protector in the Vatican; and the emperor Henry fixed his residence in the Capitol, as the lawful successor of Augustus and Charlemagne. The ruins of the Septizonium were still defended by the nephew of Gregory: the pope himself was invested in the castle of St. Angelo; and his last hope was in the courage and fidelity of his Norman vassal. Their friendship had been interrupted by some reciprocal injuries and complaints; but, on this pressing occasion, Guiscard was urged by the obligation of his oath, by his interest, more potent than oaths, by the love of fame, and his enmity to the two emperors. Unfurling the holy banner, he resolved to fly to the relief of the prince of the apostles: the 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. ^85 But the triumph of Robert was clouded by the calamities
