Everywhere in the empire the two religions lived in intimate communion. By ingratiating themselves with the Phrygian priests, the priests of Mithra obtained the support of an official institution and shared in the protection granted by the state. Moreover, men alone could participate in the secret ceremonies of the Persian liturgy, at least in the Occident. Other {66} mysteries, to which women could be admitted, had therefore to be added in order to complete them, and so the mysteries of Cybele received the wives and daughters of the Mithraists. This union had even more important consequences for the old religion of Pessinus than the partial infusion of Judaic beliefs had had. Its theology gained a deeper meaning and an elevation hitherto unknown, after it had adopted some of the conceptions of Mazdaism. The introduction of the taurobolium in the ritual of the _Magna Mater_, where it appeared after the middle of the first century, was probably connected with this transformation. We know the nature of this sacrifice, of which Prudentius gives a stirring description based on personal recollection of the proceeding. On an open platform a steer was killed, and the blood dropped down upon the mystic, who was standing in an excavation below. "Through the thousand crevices in the wood," says the poet, "the bloody dew runs down into the pit. The neophyte receives the falling drops on his head, clothes and body. He leans backward to have his cheeks, his ears, his lips and his nostrils wetted; he pours the liquid over his eyes, and does not even spare his palate, for he moistens his tongue with blood and drinks it eagerly."[33] After submitting to this repulsive sprinkling he offered himself to the veneration of the crowd. They believed that he was purified of his faults, and had become the equal of the deity through his red baptism.
