But to the point which more especially regards our subject, the feuds between Boniface and the house of Colonna. The validity of his election had been early questioned, and was long disputed, on the ground that the rights of his predecessor, as a legally chosen pope, were indefeasible by abdication. Such doubts, it may be well conceived, the fiery spirit of Boniface could ill brook, and upon a rumour that two cardinals, sons of Giovanni Colonna, had been heard to express them, he at once summoned them to his presence to state their opinion upon that delicate point. This was in 1296, after the Pontiff's fierce character had been amply developed by a reign of two years; and these cardinals instantly withdrew from Rome to the strongholds of their family, from whence they issued an answer, respectfully avowing their misgivings as to the matter in question, and offering to submit them to the decision of a general council. But their flight, and the delay of a few days, had been construed by the haughty Vicar of Christ as acts of contumacy; and even before their offensive manifesto reached him, he had directed the thunders of the Church against the two Colonna, visiting on their devoted heads the accumulated offences of all their line, without allowing them an opportunity of explanation or defence. The bull of excommunication proceeds, with more than wonted elaboration of abusive epithets, to designate the obnoxious race, as "detested by their dependants, troublesome to their neighbours, enemies to the community, rebels against the Church, turbulent in the city, fractious to their allies, thankless to their benefactors, unwilling to obey, incapable of command, devoid of humility, agitated by passion, fearless of God, regardless of man." A general proscription of their whole family and adherents, and a sequestration of their vast property, was followed up by the siege of Palestrina, their principal fief. Finding his exertions unequal to the reduction of that fortress, Boniface bethought him of the military experience of the old Ghibelline monk of Montefeltro, and demanded of him counsel, silencing his religious scruples by a preliminary absolution for the sin of reverting to worldly schemes. Thus pressed, Count Guido advised recourse to deceitful promises as the surest means of conquest; and "the bard of hell," who is an authority for this passage in his life, hence consigns him to the doom of an impenitent sinner. But let us hear the poet, through the version of Carey:--
