and the soldier of Valentinian, to entertain a secret, perhaps a treasonable, correspondence with his Barbarian allies, whose retreat had been purchased by liberal gifts, and more liberal promises. But Ætius possessed an advantage of singular moment in a female reign; he was present: he besieged, with artful and assiduous flattery, the palace of Ravenna; disguised his dark designs with the mask of loyalty and friendship; and at length deceived both his mistress and his absent rival, by a subtle conspiracy, which a weak woman and a brave man could not easily suspect. He had secretly persuaded Placidia to recall Boniface from the government of Africa; he secretly advised Boniface to disobey the Imperial summons: to the one, he represented the order as a sentence of death; to the other, he stated the refusal as a signal of revolt; and when the credulous and unsuspectful count had armed the province in his defence, Ætius applauded his sagacity in foreseeing the rebellion, which his own perfidy had excited. A temperate inquiry into the real motives of Boniface would have restored a faithful servant to his duty and to the republic; but the arts of Ætius still continued to betray and to inflame, and the count was urged, by persecution, to embrace the most desperate counsels. The success with which he eluded or repelled the first attacks, could not inspire a vain confidence, that at the head of some loose, disorderly Africans, he should be able to withstand the regular forces of the West, commanded by a rival, whose military character it was impossible for him to despise. After some hesitation, the last struggles of prudence and loyalty, Boniface despatched a trusty friend to the court, or rather to the camp, of Gonderic, king of the Vandals, with the proposal of a strict alliance, and the offer of an advantageous and perpetual settlement.
