The candidates were carefully instructed in these rules before the beginning of the celebration. Originally the instruction of the candidates was in the hands of the hierophant, who, following the example of his ancestor, Eumolpus, claimed the privilege of preparing the candidates as well as that of communicating to them the knowledge of the divine Mysteries. But the continually increasing number of candidates made it necessary to employ auxiliary instructors, and this particular work was handed over to the charge of the mystagogues, who prepared the candidates either singly or in groups, the hierophant reserving to himself the general direction of the instruction. In the course of the initiation ceremony certain words had to be spoken by the candidates, and these were made known to them in advance, although, of course, apart from their context. Admission to the second degree took place during the night between the sixth and seventh days of the celebration of the Mysteries, the candidates being led blindfolded into the temple and the ceremony opened with prayers and sacrifices by the second Archon. The candidates were crowned with myrtle wreaths, and, on entering the building, they purified themselves in a formal manner by immersing their hands in the consecrated water. Salt, laurel-leaves, barley, and crowns of flowers were also employed in the purification. The priests, vested in their sacerdotal garments, then came forward to receive the candidates. This initial ceremony took place in the outer hall of the temple, the temple itself being closed. A herald then came forward and uttered the proclamation: "Begone ye profane. Away from here, all ye that are not purified, and whose souls have not been freed from sin." In later years this formulary was changed, and in its stead the herald proclaimed: "If any atheist, or Christian, or Epicurean, is come to spy on the orgies, let him instantly retire, but let those who believe remain and be initiated, with good future." It was the final opportunity for the retirement of any who were not votaries who had by chance entered the precincts: if discovered afterwards the punishment was death. In order to make certain that no intruders remained behind all who were present had to answer certain specified questions. Then all again immersed their hands into the consecrated water and renewed their pledge of secrecy. The candidates for initiation then took off their ordinary garments and put on the skins of young does. This done, the priests wished them joy of all the happiness their initiation would bring them, and then left the candidates alone. Within a few minutes the apartment in which they were was plunged in total darkness. Lamentations and strange noises were heard; terrific peals of thunder resounded, seemingly shaking the very foundations of the temple; vivid flashes of lightning lit up the darkness, rendering it more terrible, while a more persistent light from a fire displayed fearful forms.
