While Augustus, who was initiated in the year 21 B.C., did not hesitate to show his antipathy towards the religion of the Egyptians, towards Judaism and Druidism, he was always scrupulous in observing the pledge of secrecy demanded of initiates into the Eleusinian Mysteries, and on one occasion, when it became necessary for some of the priests of the Eleusinian temple to proceed to Rome to plead before his tribunal on the question of privilege, and in the course of the evidence to speak of certain ceremonial in connection with the Mysteries of which it was not lawful to speak in the presence of the uninitiated, he ordered every one who had not received the privilege of initiation to leave the tribunal so that he and the witnesses alone remained. The Eleusinian Mysteries were not deemed inimical to the welfare of the Roman Empire as were the religions of the Egyptians, Jews, and ancient Britons. Claudius, another imperial initiate, conceived the idea of transferring the scene of the Mysteries to Rome, and, according to Suetonius, was about to put the project into execution, when it was ruled that it was obligatory that the principal scenic presentation of the Mysteries must be celebrated on the ground trodden by the feet of Demeter and where the goddess herself had ordered her temple to be erected. The initiation of the Emperor Hadrian (who succeeded where Claudius had failed, in introducing the celebration of the Mysteries into Rome) took place in A.D. 125, when he was present at the Lesser Mysteries in the spring and at the Greater Mysteries in the following autumn. In September, A.D. 129, he was again at Athens, when he presented himself for the third degree, as is known from Dion Cassius, confirmed by a letter written by the Emperor himself, in which he mentions a journey from Eleusis to Ephesus made by him at that time. Hadrian is the only imperial initiate, so far as is known, who persevered and passed through all three degrees. Since he remained at Eleusis as long as it was possible for him to do so after the completion of his initiation, it is not rash to assume that he was inspired by something more than curiosity or even by a desire to show respect. It is uncertain whether the Emperor Antonin was initiated, although from an inscription it seems probable that he was and that he should be included in the list of imperial initiates. Both Marcus Aurelius and Commodus, father and son, were initiated at the same time, at the Lesser Mysteries in March, A.D. 176, and at the Greater Mysteries in the following September. Septimius Severus was initiated before he ascended the throne. There was, as stated, three degrees, and the ordinary procedure with regard to initiation was as follows:--
