In A.D. 364, a law prohibiting nocturnal rites was published by Valentinian, but Praetextatus, whom Julian had constituted governor of Achaia, prevailed on him to revoke it, urging that the lives of the Greeks would be rendered utterly unsupportable if he deprived them of this, their most holy and comprehensive festival. Much has been made by some writers of the fact that the ceremonies were held at night, but in the early days of Christianity also it was the custom for Christians to forgather either at night or before daybreak, a circumstance which led to their assemblies being known as _antelucani_ and themselves as _lucifugæ_ or "light-haters," by way of reproach. About the beginning of the fifth century Theodosius the Great prohibited and almost totally extinguished the pagan theology in the Roman Empire, and the Eleusinian Mysteries suffered in the general destruction. It is probable, however, that the Mysteries were celebrated secretly in spite of the severe edicts of Theodosius and that they were partly continued through the dark ages, though stripped of their splendour. It is certain that many rites of the pagan religion were performed under the dissembled name of convivial meetings, long after the publication of the Emperor's edicts, and Psellius informs us that the Mysteries of Ceres existed in Athens until the eighth century of the Christian era and were never totally suppressed. The Festival of the Greater Mysteries--and this was, of course, by far the more important--began on the 15th of the month of Boedromion, corresponding roughly with the month of September, and lasted until the 23rd of the same month. During that time it was unlawful to arrest any man present, or present any petition except for offences committed at the Festival, heavy penalties being inflicted for breaches of this law, the penalties fixed being a fine of not less than a thousand drachmas, and some assert that transgressors were even put to death. [Footnote 1: From two inscriptions found at Eleusis it would appear that it was customary to make the name public after the death of the hierophant. It seems also to have been the practice to make the name known to the initiate under the pledge of secrecy. Sir James Frazer thinks that the names were, in all probability, engraved on tablets of bronze or lead and then thrown into deep water in the Gulf of Salamis.] III PROGRAMME OF THE GREATER MYSTERIES The following is the programme of the "Greater Mysteries," which extended over a period of ten days. The various functions were characterized by the greatest possible solemnity and decorum, and the ceremonies were regarded as "religious" in the highest interpretation of that term.
