The History of the Decline and Fall of the Roman Empire - Edward Gibbon [1625]
[Footnote 63: Between the exorbitant claims, and narrow concessions, of interest and prejudice, from which even Muratori (Antiquitat. tom. i. p. 63-68) is not exempt, I have been guided, in the limits of the Exarchate and Pentapolis, by the Dissertatio Chorographica Italiae Medii Aevi, tom. x. p. 160-180.]
[Footnote 64: Spoletini deprecati sunt, ut eos in servitio B. Petri receperet et more Romanorum tonsurari faceret, (Anastasius, p. 185.) Yet it may be a question whether they gave their own persons or their country.]
[Footnote 65: The policy and donations of Charlemagne are carefully examined by St. Marc, (Abrege, tom. i. p. 390-408,) who has well studied the Codex Carolinus. I believe, with him, that they were only verbal. The most ancient act of donation that pretends to be extant, is that of the emperor Lewis the Pious, (Sigonius, de Regno Italiae, l. iv. Opera, tom. ii. p. 267-270.) Its authenticity, or at least its integrity, are much questioned, (Pagi, A.D. 817, No. 7, &c. Muratori, Annali, tom. vi. p. 432, &c. Dissertat. Chorographica, p. 33, 34;) but I see no reasonable objection to these princes so freely disposing of what was not their own.]
[Footnote 66: Charlemagne solicited and obtained from the proprietor, Hadrian I., the mosaics of the palace of Ravenna, for the decoration of Aix-la-Chapelle, (Cod. Carolin. epist. 67, p. 223.)]
[Footnote 67: The popes often complain of the usurpations of Leo of Ravenna, (Codex Carolin, epist. 51, 52, 53, p. 200-205.) Sir corpus St. Andreae fratris germani St. Petri hic humasset, nequaquam nos Romani pontifices sic subjugassent, (Agnellus, Liber Pontificalis, in Scriptores Rerum Ital. tom. ii. pars. i. p. 107.)]
Fraud is the resource of weakness and cunning; and the strong, though ignorant, Barbarian was often entangled in the net of sacerdotal policy. The Vatican and Lateran were an arsenal and manufacture, which, according to the occasion, have produced or concealed a various collection of false or genuine, of corrupt or suspicious, acts, as they tended to promote the interest of the Roman church. Before the end of the eighth century, some apostolic scribe, perhaps the notorious Isidore, composed the decretals, and the donation of Constantine, the two magic pillars of the spiritual and temporal monarchy of the popes. This memorable donation was introduced to the world by an epistle of Adrian the First, who exhorts Charlemagne to imitate the liberality, and revive the name, of the great Constantine. ^68 According to the legend, the first of the Christian emperors was healed of the leprosy, and purified in the waters of baptism, by St. Silvester, the Roman bishop; and never was physician more gloriously recompensed. His royal proselyte withdrew from the seat and patrimony of St. Peter; declared his resolution of founding a new capital in the East; and resigned to the popes the free and perpetual sovereignty of Rome, Italy, and the provinces of the West. ^69 This fiction was productive of the most beneficial effects. The Greek princes were convicted of the guilt of usurpation; and the revolt of Gregory was the claim of his lawful inheritance. The popes were delivered from their debt of gratitude; and the nominal gifts of the Carlovingians were no more than the just and irrevocable restitution of a scanty portion of the ecclesiastical state. The sovereignty of Rome no longer depended on the choice of a fickle people; and the successors of St. Peter and Constantine were invested with the purple and prerogatives of the Caesars. So deep was the ignorance and credulity of the times, that the most absurd of fables was received, with equal reverence, in Greece and in France, and is still enrolled among the decrees of the canon law. ^70 The emperors, and the Romans, were incapable of discerning a forgery, that subverted their rights and freedom; and the only opposition proceeded from a Sabine monastery, which, in the beginning of the twelfth century, disputed the truth and validity
