[3] Even Petrarch, in his letter to four Cardinals (Lett. Fam. xi.
16, ed. Fracassetti) on the reformation of the Roman Commonwealth,
recommends the exclusion of the neighboring burghs and all
strangers, inclusive of the Colonna and Orsini families, from the
franchise. None but pure Romans, how to be discovered from the
_colluviet omnium gentium_ deposited upon the Seven Hills by

peroration of his argument (op. cit. vol. iii. p. 95). In other

In the North of Italy not a few of the greater vassals, among whom may
be mentioned the houses of Canossa, Montferrat, Savoy, and Este,

this episode, than which nothing more dramatic is presented by the
history of modern nations, it must be enough to point out here that the
