The ancients said that the Initiates would be more happy after death than other mortals; and that, while the souls of the Profane on leaving their bodies, would be plunged in the mire, and remain buried in darkness, those of the Initiates would fly to the Fortunate Isles, the abode of the Gods.
Plato said that the object of the Mysteries was to re-establish the soul in its primitive purity, and in that state of perfection which it had lost. Epictetus said, "whatever is met with therein has been instituted by our Masters, for the instruction of man and the correction of morals."
Proclus held that initiation elevated the soul, from a material, sensual, and purely human life, to a communion and celestial intercourse with the Gods; and that a variety of things, forms, and species were shown Initiates, representing the first generation of the Gods.
Purity of morals and elevation of soul were required of the Initiates. Candidates were required to be of spotless reputation and irreproachable virtue. Nero, after murdering his mother, did not dare to be present at the celebration of the Mysteries: and Antony presented himself to be initiated, as the most infallible mode of proving his innocence of the death of Avidius Cassius.
The Initiates were regarded as the only fortunate men. "It is upon us alone," says Aristophanes, "shineth the beneficent day-star. We alone receive pleasure from the influence of his rays; we, who are initiated, and who practise toward citizen and stranger every possible act of justice and piety." And it is therefore not surprising that, in time, initiation came to be considered as necessary as baptism afterward was to the Christians; and that not to have been admitted to the Mysteries was held a dishonor.
"It seems to me," says the great orator, philosopher, and moralist, Cicero, "that Athens, among many excellent inventions, divine and very useful to the human family, has produced none comparable to the Mysteries, which for a wild and ferocious life have substituted humanity and urbanity of manners. It is with good reason they use the term initiation; for it is through them that we in reality have learned the first principles of life; and they not only teach us to live in a manner more consoling and agreeable, but they soften the pains of death by the hope of a better life hereafter."
Where the Mysteries originated is not known. It is supposed they came from India, by the way of Chaldæa, into Egypt, and thence were carried into Greece. Wherever they arose, they were practised among all the ancient nations; and, as was usual, the Thracians, Cretans, and Athenians each claimed the honor of invention, and each insisted that they had borrowed nothing from any other people.
In Egypt and the East, all religion, even in its most poetical forms, was more or less a mystery; and the chief reason why, in Greece, a distinct name and office were assigned to the Mysteries, was because the superficial popular theology left a want unsatisfied, which religion in a wider sense alone could supply. They were practical acknowledgments of the insufficiency of the popular religion to satisfy the deeper thoughts and aspirations of the mind. The vagueness of symbolism might perhaps reach what a more palpable and conventional creed could not. The former, by its indefiniteness, acknowledged the abstruseness of its subject; it treated a mysterious subject mystically; it endeavored to illustrate what it could not explain; to excite an appropriate feeling, if it could not develop an adequate idea; and made the image a mere subordinate conveyance for the conception, which itself never became too obvious or familiar.
The instruction now conveyed by books and letters was of old conveyed by symbols; and the priest had to invent or to perpetuate a display of rites and exhibitions, which were not only more attractive to the eye than words, but often to the mind more suggestive and pregnant with meaning.
Afterward, the institution became rather moral and political, than religious. The civil magistrates shaped the ceremonies to political ends in Egypt; the sages who carried them from that country to Asia, Greece, and the North of Europe, were all kings or legislators. The chief magistrate presided at those of Eleusis, represented by an officer styled King: and the Priest played but a subordinate part.
