The Eleusinian Mysteries are believed to be of considerable antiquity, deriving from religious practice of the Mycenaean period and thus predating the Greek Dark Ages. One line of thought by modern scholars has been that the Mysteries were intended "to elevate man above the human sphere into the divine and to assure his redemption by making him a god and so conferring immortality upon him."
Comparative study shows parallels between these Greek rituals and similar systems — some of them older — in the Near East (see Religions of the Ancient Near East). These cults are the mysteries of Isis and Osiris in Egypt, the Adoniac of Syrian cults, the Persian mysteries, and the Phrygian Cabirian mysteries. Some scholars argued that the Eleusinian cult was a continuation of a Minoan cult, probably affected by the Near East.
