Ambitious of restoring the splendor of the purple, Frederic the First
invaded the republics of Lombardy, with the arts of a statesman, the
valor of a soldier, and the cruelty of a tyrant. The recent discovery of
the Pandects had renewed a science most favorable to despotism; and his
venal advocates proclaimed the emperor the absolute master of the lives
and properties of his subjects. His royal prerogatives, in a less odious
sense, were acknowledged in the diet of Roncaglia; and the revenue of
Italy was fixed at thirty thousand pounds of silver, [146] which were
multiplied to an indefinite demand by the rapine of the fiscal officers.
The obstinate cities were reduced by the terror or the force of his
arms: his captives were delivered to the executioner, or shot from
his military engines; and. after the siege and surrender of Milan,
the buildings of that stately capital were razed to the ground, three
hundred hostages were sent into Germany, and the inhabitants were
dispersed in four villages, under the yoke of the inflexible conqueror.
[147] But Milan soon rose from her ashes; and the league of Lombardy was
cemented by distress: their cause was espoused by Venice, Pope
Alexander the Third, and the Greek emperor: the fabric of oppression
was overturned in a day; and in the treaty of Constance, Frederic
subscribed, with some reservations, the freedom of four-and-twenty
cities. His grandson contended with their vigor and maturity; but
Frederic the Second [148] was endowed with some personal and peculiar
advantages. His birth and education recommended him to the Italians;
and in the implacable discord of the two factions, the Ghibelins were
attached to the emperor, while the Guelfs displayed the banner of
liberty and the church. The court of Rome had slumbered, when his father
Henry the Sixth was permitted to unite with the empire the kingdoms of
Naples and Sicily; and from these hereditary realms the son derived an
ample and ready supply of troops and treasure. Yet Frederic the Second
was finally oppressed by the arms of the Lombards and the thunders of
the Vatican: his kingdom was given to a stranger, and the last of his
family was beheaded at Naples on a public scaffold. During sixty years,
no emperor appeared in Italy, and the name was remembered only by the
ignominious sale of the last relics of sovereignty.
