After the Greek conquest, the new city of Alexandria became the centre of Egyptian religious life, and indeed of the religious life of the whole Hellenic world. A great temple, the Serapeum, was set up by Ptolemy I at which a sort of trinity of gods was worshipped. These were Serapis (who was Osiris-Apis rechristened), Isis and Horus. These were not regarded as separate gods but as three aspects of one god, and Serapis was identified with the Greek Zeus, the Roman Jupiter and the Persian sun-god. This worship spread wherever the Hellenic influence extended, even into North India and Western China. The idea of immortality, an immortality of compensations and consolation, was eagerly received by a world in which the common life was hopelessly wretched. Serapis was called “the saviour of souls.” “After death,” said the hymns of that time, “we are still in the care of his providence.” Isis attracted many devotees. Her images stood in her temples, as Queen of Heaven, bearing the infant Horus in her arms. Candles were burnt before her, votive offerings were made to her, shaven priests consecrated to celibacy waited on her altar. The rise of the Roman empire opened the western European world to this growing cult. The temples of Serapis-Isis, the chanting of the priests and the hope of immortal life, followed the Roman standards to Scotland and Holland. But there were many rivals to the Serapis-Isis religion. Prominent among these was Mithraism. This was a religion of Persian origin, and it centred upon some now forgotten mysteries about Mithras sacrificing a sacred and benevolent bull. Here we seem to have something more primordial than the complicated and sophisticated Serapis-Isis beliefs. We are carried back directly to the blood sacrifices of the heliolithic stage in human culture. The bull upon the Mithraic monuments always bleeds copiously from a wound in its side, and from this blood springs new life. The votary to Mithraism actually bathed in the blood of the sacrificial bull. At his initiation he went beneath a scaffolding upon which a bull was killed so that the blood could actually run down on him. Both these religions, and the same is true of many other of the numerous parallel cults that sought the allegiance of the slaves and citizens under the earlier Roman emperors, are personal religions. They aim at personal salvation and personal immortality. The older religions were not personal like that; they were social. The older fashion of divinity was god or goddess of the city first or of the state, and only secondarily of the individual. The sacrifices were a public and not a private function. They concerned collective practical needs in this world in which we live. But the Greeks first and now the Romans had pushed religion out of politics. Guided by the Egyptian tradition religion had retreated to the other world. BUST OF THE EMPEROR COMMODUS, A.D. 180-192 BUST OF THE EMPEROR COMMODUS, A.D. 180-192
