Thus we see that before this hymn was written the myth was fully developed at Eleusis. There Demeter, Kore, and Pluto had their place, and with them were associated certain heroic personages. A temple and altar to the two goddesses already existed, and mysteries were celebrated which gave to those who might see them and share in them the warrant of a better lot in death than that for which the uninitiate might hope. The date at which the mysteries were established cannot be determined. This is no place for the speculations of the learned in detail, but they seem to have existed as early as the eighth century, and indeed they probably go back to a much remoter antiquity; yet there is no mention of them in Homer or Hesiod. In their earliest form they evidently consisted of certain religious ceremonies connected with agriculture by which the dead grain was called to life in the spring. The grain and the earth from which it sprang were worshipped as the corn-mother, Demeter, and then by a development natural in such religions the goddess was doubled and Kore, the maiden, came into existence beside Demeter. In the cult of these goddesses various rites had developed—fasting, purifications, and night vigils; a myth grew up to explain the ritual and the relation of the two goddesses, with whom a god of the dead was early associated; so something like the story in the Homeric hymn came into being. The agricultural festival was gradually transformed into one of profound meaning, by partaking in which one gained an assurance of future happiness. The wonderful miracle of reviving vegetation, of the grain which dies in the ground and springs anew to life, has often served as the warrant of man’s longing for a revival of his own life, as an assurance of his hope of immortality. So gods and goddesses of agriculture or of vegetation, which grows and dies and grows again, have become for men the lords of life and death, as we have already seen in the case of Dionysus. The English word mystery is somewhat misleading in such a connection. A mystery in the Greek sense is a secret ritual to which only those may be admitted who have first been prepared by some rites of purification or probation. Such, for example, is the Christian Eucharist to which the Greek word μυστήριον was freely applied. After the proper ritual of initiation, through which the neophyte is guided by one previously initiate and expert, he may take part in the secret performances, which are thought to confer some special power or to bring him into close and privileged relation to divinity.
