II
What may be regarded as a second recension of the Roman rite is the Order of the Coronation of an Emperor given in Hittorp’s Ordo Romanus[48]. This is of the tenth or eleventh century. It differs considerably from the last recension, and is more fixed and definite in character, but is still definitely Roman.
First the Emperor takes the oath as follows: In nomine Christi promitto, spondeo, atque polliceor ego N. imperator coram Deo et beato Petro apostolo, me protectorem ac defensorem esse huius ecclesiae sanctae Romanae in omnibus utilitatibus in quantum divino fultus fuero adiutorio, secundum scire meum ac posse.
As he enters St Peter’s the Cardinal Bishop of Albano meets him at the silver door, and recites the prayer, Deus in cuius manu corda sunt regum, a new form. Inside the church the Cardinal Bishop of Porto says the prayer Deus inenarrabilis auctor mundi, another new form, and after the Litany has been said, before the Confessio of St Peter, the Cardinal Bishop of Ostia anoints the Emperor on the right arm and between the shoulders with the oil of catechumens, using the form Domine Deus Omnipotens cuius est omnis potestas—again another new form, which however is found in the rite by which Pope John VIII crowned Louis II of France at Troyes in 877. The Pope then crowns the Emperor, using one of three forms which are given, Accipe signum gloriae in nomine Patris, etc., or (alia) Accipe coronam a Domino Deo praedestinatam, or (alia) with the prayer Deus Pater aeternae gloriae.
