instrument of the divine will, accepted a dignity which he might have wished to receive at some later time or in some other way. If, therefore, any positive conclusion be adopted, it would seem to be that Charles, although he had probably given a more or less vague consent to the project, was surprised and disconcerted by a sudden fulfilment which interrupted his own carefully studied designs. And although a deed which changed the history of the world was in any case no accident, it may well have worn to the Frankish and Roman spectators the air of a surprise. For there were no preparations apparent in the church; the king was not, like his Teutonic successors in aftertime, led in procession to the pontifical throne: suddenly, at the very moment when he rose from the sacred hollow where he had knelt among the ever-burning lamps before the holiest of Christian relics--the body of the prince of the Apostles--the hands of that Apostle's representative placed upon his head the crown of glory and poured upon him the oil of sanctification. There was something in this to thrill the beholders with the awe of a divine presence, and make them hail him whom that presence seemed almost visibly to consecrate, the 'pious and peace-giving Emperor, crowned of God.' [Sidenote: Theories of the motives of Charles.] The reluctance of Charles to assume the imperial title is ascribed by Eginhard to a fear of the jealous hostility of the Greeks, who could not only deny his claim to it, but might disturb by their intrigues his dominions in Italy. Accepting this statement, the problem remains, how is this reluctance to be reconciled with those acts of his which clearly shew him aiming at the Roman crown? An ingenious and probable, if not certain solution, is suggested by a recent historian[67], who argues from a minute examination of the previous policy of Charles, that while it was the great object of his reign to obtain the crown of the world, he foresaw at the same time the opposition of the Eastern Court, and the want of legality from which his title would in consequence suffer. He was therefore bent on getting from the Byzantines, if possible, a transference of their crown; if not, at least a recognition of his own: and he appears to have hoped to win this by the negotiations which had been for some time kept on foot with the Empress Irene. Just at this moment came the coronation by Pope Leo, interrupting these deep-laid schemes, irritating the Eastern Court, and forcing Charles into the position of a rival who could not with dignity adopt a soothing or submissive tone. Nevertheless, he seems not even then to have abandoned the hope of obtaining a peaceful recognition. Irene's crimes did not prevent him, if we may credit Theophanes[68], from seeking her hand in marriage. And when the project of thus uniting the East and West in a single Empire, baffled for a time by the opposition of her minister Ætius, was rendered
