The ceremonies of the inauguration naturally tended in process of time to develope. The election by the Senate, as has been remarked, became more and more of a form, and new customs gradually came into being. A considerable developement is noticeable in the account of the inauguration of Julian, though the whole ceremony in his case was under the circumstances somewhat informal and makeshift. It is the army which elects him. In spite of his protests he is acclaimed as Emperor; he is then elevated on a shield; and finally he is crowned, a torque serving temporarily to represent the diadem. Afterwards, we are told, he assumed a gorgeous diadem at Vienne[9]. The elevation on a shield, which henceforward always occurs in the inauguration ceremonies, appears for the first time at Julian’s accession to the imperial throne. It was a custom followed among the Teutonic tribes[10], and was doubtless introduced by the Teutonic soldiers who formed so important a part of the Roman armies at this time. The diadem, which is of oriental origin, was perhaps introduced by Aurelian. It seems to have been habitually used by Constantine, and there was a gradual advance during this period in the matter of ceremonial and the sumptuousness of the imperial vestments. There is no sign, for some time after the acceptance of Christianity as the religion of the Empire, of any Christian influence on the rites of inauguration. It is not until the time of the Emperor Leo I that we meet with the coronation rite in the religious sense of the term. In the year 457 the Emperor Leo I was formally crowned and invested as Emperor with religious rites. Constantine Porphyrogenitus[11], to whom we owe so much of our knowledge of the court functions and ceremonial of the Byzantine period, describes the rite which took place at the accession of Leo. The new Emperor, accompanied by the high officials of the Empire, went down in state to the Hippodrome, in which was gathered together a vast concourse of people. Here he ascended a lofty tribunal in view of all the people and was greeted with acclamations. A _maniakis_ (apparently a kind of fillet) is placed upon his head, and another in his hand, amid the cheers of the people. Then under the cover of a _testudo_, raised by the _candidati_, he is arrayed in the imperial vestments, and so shews himself to the people, with the diadem on his head and the imperial shield and spear in his hands. He is thereupon greeted with the ritual formula, _Mighty and victorious and august, prosperously, prosperously. Many years, Leo Augustus, thou shalt reign. God will keep this realm, God will keep this Christian realm_, and other such things. The Emperor then makes a speech to the people, and promises the customary Donative.
