The rite seems to have changed very little in the process of time. Ordo XII[150], which is of the twelfth century, gives a little more information. On the Sunday after his election the Pope proceeds to St Peter’s, and there before the high altar is consecrated bishop by the Bishop of Ostia and other bishops. The consecration over, the Cardinal Deacon of St Laurence places the Pallium on the high altar, whence the Archdeacon takes it and invests the Pope in it saying: _Accipe pallium, plenitudinem scilicet pontificalis officii, ad honorem omnipotentis Dei et gloriosissimae Virginis eius genitricis et beatorum apostolorum Petri et Pauli et sanctas Romanae ecclesiae_. The Pope then celebrates Mass. After the Laudes, the Epistle and Gospel are read both in Latin and Greek. Mass being finished, the Pope returns to his palace with the Tiara on his head, but there is no indication of any ceremonial crowning having taken place. Ordo XIV[151] of the fourteenth century is fuller. The Pope is now generally already a bishop at the time of his election. The newly-elected Pope proceeds to St Peter’s and begins Mass. After the _Confiteor_ he takes his seat before a faldstool between his throne and the altar, and there prayers are said for him by the Cardinal Bishops of Albano, Porto and Ostia. First the Bishop of Albano says the prayer: _Deus qui adesse non dedignaris ubicumque devota mente invocaris, adesto quaesumus invocationibus nostris et huic famulo tuo N. quem ad culmen apostolicum commune iudicium tuae plebis elegit ubertatem supernae benedictionis infunde, ut sentiat se tuo munere ad hunc apicem pervenisse_. Next the Bishop of Porto says the second prayer, _Supplicationibus, Omnipotens Deus, effectum consuetae pietatis impende, et gratia Spiritus Sancti hunc famulum tuum N. perfunde; ut qui in capite ecclesiarum nostrae servitutis mysterio constituitur, tuae virtutis soliditate roboretur_. The Bishop of Ostia says the third prayer, _Deus qui Apostolum tuum Petrum inter caeteros coapostolos primatum tenere voluisti, eique universae Christianitatis molem superimposuisti; respice propitius quaesumus hunc famulum tuum N. quem de humili cathedra violenter sublimatum in thronum eiusdem apostolorum principis sublimamus: ut sicut profectibus tantae dignitatis augetur, ita virtutum meritis cumuletur; quatenus ecclesiasticae universitatis onus, te adiuvante, digne ferat, et a te qui es beatitudo tuorum meritam vicem recipiat_.
