direct the deliberations of this synod, although legates from the Pope were present--he also caused a treatise to be drawn up stating and urging its conclusions; he pressed Hadrian to declare Constantine VI a heretic for enouncing doctrines to which Hadrian had himself consented. There are letters of his extant in which he lectures Pope Leo in a tone of easy superiority, admonishes him to obey the holy canons, and bids him pray earnestly for the success of the efforts which it is the monarch's duty to make for the subjugation of pagans and the establishment of sound doctrine throughout the Church. Nay, subsequent Popes themselves[71] admitted and applauded the despotic superintendence of matters spiritual which he was wont to exercise, and which led some one to give him playfully a title that had once been applied to the Pope himself, 'Episcopus episcoporum.' [Sidenote: The imperial office in its ecclesiastical relations.] [Sidenote: Capitulary of A.D. 802.] Acting and speaking thus when merely king, it may be thought that Charles needed no further title to justify his power. The inference is in truth rather the converse of this. Upon what he had done already the imperial title must necessarily follow: the attitude of protection and control which he held towards the Church and the Holy See belonged, according to the ideas of the time, especially and only to an Emperor. Therefore his coronation was the fitting completion and legitimation of his authority, sanctifying rather than increasing it. We have, however, one remarkable witness to the importance that was attached to the imperial name, and the enhancement which he conceived his office to have received from it. In a great assembly held at Aachen, A.D. 802, the lately-crowned Emperor revised the laws of all the races that obeyed him, endeavouring to harmonize and correct them, and issued a capitulary singular in subject and tone[72]. All persons within his dominions, as well ecclesiastical as civil, who have already sworn allegiance to him as king, are thereby commanded to swear to him afresh as Cæsar; and all who have never yet sworn, down to the age of twelve, shall now take the same oath. 'At the same time it shall be publicly explained to all what is the force and meaning of this oath, and how much more it includes than a mere promise of fidelity to the monarch's person. Firstly, it binds those who swear it to live, each and every one of them, according to his strength and knowledge, in the holy service of God; since the lord Emperor cannot extend over all his care and discipline. Secondly, it binds them neither by force nor fraud to seize or molest any of the goods or servants of his crown. Thirdly, to do no violence nor treason towards the holy Church, or to widows, or orphans, or strangers, seeing that the lord Emperor has been appointed, after the Lord and his saints, the protector and defender of all such.'
