The oath is slightly varied. It is made, as usual, in the church of St Mary in Turri, where the Emperor is received by the canons as a brother canon, and the Emperor swears that he will be the protector of the Roman Church, but does not swear fealty to the Pope and his successors as in the preceding recension. In St Peter’s the Bishops of Albano and Porto say their accustomed prayers, and the Litany is said before St Peter’s altar. Then the Bishop of Ostia, before the altar of St Maurice, anoints the Emperor on the right arm and between the shoulders with the prayers _Domine Deus Omnipotens cuius est omnis potestas_ and _Deus Dei Filius_. After the anointing the Pope kisses the Emperor ‘sicut unum ex diaconibus’ and Mass is begun at the altar of St Peter, the collect _Deus regnorum omnium_ being said after the collect for the day. After the gradual the Pope first sets a mitre on the Emperor’s head, and then crowns him with the form _Accipe signum gloriae_: the Sceptre and Orb are then delivered, though no forms of delivery are given, and lastly the Sword is delivered with the form _Accipe gladium ad vindictam_, etc., a longer form than hitherto used containing the words ‘per nostras manus, licet indignas, vice tamen et auctoritate beatorum apostolorum consecratas imperialiter tibi concessum,’ and girt on with the words _Accingere gladio tuo super femur_, etc., and the Emperor thereupon kisses the Pope’s feet. After the gradual the Laudes are sung. At the offertory the Emperor offers first gold, and then acting as sub-deacon (more subdiaconi) offers the chalice and water-cruet to the Pope. The Empress is met at the entrance of St Peter’s and the prayer _Omnipotens sempiterne Deus fons et origo_, etc., is there said. When the Empress has been crowned she is brought to the Pope, who, after reciting the prayer _Deus qui solus habes immortalitatem_, anoints her with the form _Spiritus Sancti gratia_, this form being longer than in the last recension. Then he places the mitre on her head ‘ita quod cornua mitrae sint a dextris et a sinistris,’ and finally crowns her with the form _Officio nostrae indignitatis in imperatricem solemniter benedicta accipe coronam imperialis excellentiae_, etc. After the Communion it is added that the Pope may, if he wish, say the prayers _Prospice, quaesumus, Domine Omnipotens Deus serenis obtutibus_, _Benedic, Domine, quaesumus, hunc principem_, or (alia) _Deus Pater aeternae gloriae_, all of which occur in earlier Roman rites.
