All will be given to patient merit; all will be denied to rude importunity."¹² Neither the emperor nor the senate could maintain these lofty pretensions of dominion and liberty. United with the pope, and suspicious of the Romans, Frederic continued his march to the Vatican; his coronation was disturbed by a sally from the Capitol; and if the numbers and valor of the Germans prevailed in the bloody conflict, he could not safely encamp in the presence of a city of which he styled himself the sovereign. About twelve years afterwards, he besieged Rome, to seat an antipope in the chair of St. Peter; and twelve Pisan galleys were introduced into the Tyber: but the senate and people were saved by the arts of negotiation and the progress of disease; nor did Frederic or his successors reiterate the hostile attempt. Their laborious reigns were exercised by the popes, the crusades, and the independence of Lombardy and Germany: they courted the alliance of the Romans; and Frederic the Second offered in the Capitol the great standard, the Caroccio of Milan.¹³ After the extinction of the house of Swabia, they were banished beyond the Alps: and their last coronations betrayed the impotence and poverty of the Teutonic Cæsars.¹⁴

Under the reign of Adrian, when the empire extended from the Euphrates to the ocean, from Mount Atlas to the Grampian hills, a fanciful historian¹⁵ amused the Romans with the picture of their ancient wars. "There was a time," says Florus, "when Tibur and Præneste, our summer retreats, were the objects of hostile vows in the Capitol, when we dreaded the shades of the Arician groves, when we could triumph without a blush over the nameless villages of the Sabines and Latins, and even Corioli could afford a title not unworthy of a victorious general." The pride of his contemporaries was gratified by the contrast of the past and the present: they would have been humbled by the prospect of futurity; by the prediction, that after a thousand years, Rome, despoiled of empire, and contracted to her primæval limits, would renew the same hostilities, on the same ground which was then decorated with her villas and gardens. The adjacent territory on either side of the Tyber was always claimed, and sometimes possessed, as the patrimony of St. Peter; but the barons assumed a lawless independence, and the cities too faithfully copied the revolt and discord of the metropolis. In the twelfth and thirteenth centuries the Romans incessantly labored to reduce or destroy the contumacious vassals of the church and senate; and if their headstrong and selfish ambition was moderated by the pope, he often encouraged their zeal by the alliance of his spiritual arms. Their warfare was that of the first consuls and dictators, who were taken from the plough. The assembled in arms at the foot of the Capitol; sallied from the gates, plundered or burnt the harvests of their neighbors, engaged in tumultuary conflict, and returned home after an expedition of fifteen or twenty days. Their sieges were tedious and unskilful: in the use of victory, they indulged the meaner passions of jealousy and revenge; and instead of adopting the valor, they trampled on the misfortunes, of their adversaries. The captives, in their shirts, with a rope round their necks, solicited their pardon: the fortifications, and even the buildings, of the rival cities, were demolished, and the inhabitants were scattered in the adjacent villages. It was thus that the seats of the cardinal bishops, Porto, Ostia, Albanum, Tusculum, Præneste, and Tibur or Tivoli, were successively overthrown by the ferocious hostility of the Romans.¹⁶ Of these,¹⁷ Porto and Ostia, the two keys of the Tyber, are still vacant and desolate: the marshy and unwholesome banks are peopled with herds of buffaloes, and the river is lost to every purpose of navigation and trade. The hills, which afford a shady retirement from the autumnal heats, have again smiled with the blessings of peace; Frescati has arisen near the ruins of Tusculum; Tibur or Tivoli has resumed the honors of a city,¹⁸ and the meaner towns of Albano and Palestrina are decorated with the villas of the cardinals and princes of Rome. In the work of destruction, the ambition of the Romans was often checked and repulsed by the neighboring cities and their allies: in the first siege of Tibur, they were driven from their camp; and the battles of Tusculum¹⁹ and Viterbo²⁰ might be compared in their relative state to the memorable fields of Thrasymene and Cannæ. In the first of these petty wars, thirty thousand Romans were overthrown by a thousand German horse, whom Frederic Barbarossa had detached to the relief of Tusculum: and if we number the slain at three, the prisoners at two, thousand, we shall embrace the most authentic and moderate account. Sixty-eight years afterwards they marched against Viterbo in the ecclesiastical state with the whole force of the city; by a rare coalition the Teutonic eagle was blended, in the adverse banners, with the keys of St. Peter; and the pope's auxiliaries were commanded by a count of Thoulouse and a bishop of Winchester. The Romans were discomfited with shame and slaughter: but the English prelate must have indulged the vanity of a pilgrim, if he multiplied their numbers to one hundred, and their loss in the field to thirty, thousand men. Had the policy of the senate and the discipline of
