When the time for their initiation arrived, they were brought into the temple; and to inspire the greater reverence and terror, the ceremony was performed in the night. Wonderful things passed upon this occasion. Visions were seen, and voices heard, of an extraordinary kind. A sudden splendour dispelled the darkness of the place; and disappearing immediately, added new horrors to the gloom. Apparitions, claps of thunder, earthquakes, improved the terror and amazement; whilst the person admitted, stupified, sweating through fear, heard trembling the mysterious volumes read to him. These nocturnal rites were attended with many disorders, which the severe law of silence, imposed on the persons initiated, prevented from coming to light. The president in this ceremony was called a Hierophant. He wore a peculiar habit, and was not admitted to marry. He had three colleagues; one who carried a torch; another, a herald, whose office was to pronounce certain mysterious words; and a third, to attend at the altar. Besides these officers, one of the principal magistrates of the city was appointed to take care that all the ceremonies of this feast were exactly observed. He was called the king, and was one of the nine Archons. His business was to offer prayers and sacrifices. The people gave him four assistants. He had, besides, ten other ministers to assist him in the discharge of his duty, and particularly in offering sacrifices. The Athenians initiated their children of both sexes very early into these mysteries, and would have thought it criminal to have let them die without such an advantage. It was regularly celebrated every fifth year; that is, after a revolution of four years: and history records, that it was never interrupted, except upon the taking of Thebes by Alexander the Great. It was continued down to the time of the Christian emperors; and Valentinian would have abolished it, if Prætextatus, the proconsul of Greece, had not represented in the most lively and affecting terms the universal sorrow which the abrogation of that feast would occasion among the people; upon which it was suffered to subsist. It is supposed to have been finally suppressed by Theodosius the Great.
