The revenues from the celebrations must have been considerable. At both the Lesser Mysteries and the Greater Mysteries a charge of one obole a day was demanded from each one attending, which was given to the hierophant. The hierocceryx received a half-obole a day, and other assistants a similar sum. In current coinage an obole was of the value of a fraction over 1 1/4d. IV THE INITIATORY RITES Two important facts must be set down with regard to the Mysteries: first, the general custom of all Athenian citizens, and afterwards of all Greeks generally, and eventually of many foreigners, to seek admission into the Eleusinian Mysteries in the only possible manner--viz. by initiation; and, second, the scrupulous care exercised by the Eumolpides to ensure that only persons duly qualified, of irreproachable--or, at any rate, of circumspect, character passed the portals. In the earlier days of the Mysteries it was a necessary condition that the candidates for initiation should be free-born Athenians, but in course of time this rule was relaxed, until eventually strangers (as residents outside Athens were called), aliens, slaves, and even courtesans, were admitted, on condition that they were introduced by a mystagogue, who was, of course, an Athenian. An interesting inscription was discovered a few years ago demonstrating the fact that the public slaves of the city were initiated at the public expense. From historical records we learn that Lysias was enabled without difficulty to secure the initiation of his mistress, Metanira, who was then in the service of the courtesan Nicareta. There always prevailed, however, the strict rule that no one could be admitted who had been guilty of murder or homicide, wilful or accidental, or who had been convicted of witchcraft, and all who had incurred the capital penalty for conspiracy or treason were also excluded. Nero sought admission into the Eleusinian Mysteries, but was rejected because of the many slaughters connected with his name. Antoninus, when he would purge himself before the world of the death of Avidius Cassius, elected to be initiated into the Eleusinian Mysteries, it being recognized at that time that none was admitted into them who was justly guilty of heinous immorality or crime.
