The nine days of the Festival are said to be significant of the descent of the soul. The soul, in falling from her original, divine abode in the heavens, passes through eight spheres, viz. the inerratic sphere and the seven planets, assuming a different body and employing different energies in each, finally becoming connected with the sublunary world and a terrene body on the ninth. Demeter and the foundation of the art of tillage are said to signify the descent of intellect into the realms of generation, the greatest benefit and ornament which a material nature is capable of receiving. Without the possibility of the participation of intellect in the lower material sphere nothing but an irrational and a brutal life would subsist. But, according to some writers, the initiates into the third degree were taught that the gods and goddesses were only dead mortals, subject while alive to the same passions and infirmities as themselves; and they were taught to look upon the Supreme Cause, the Creator of the Universe, as pervading all things by His virtue and governing all things by His power. Thus the meaning of _Mystes_ is given as "one who sees things in disguise," and that of _Epopt_ as "one who sees things as they are, without disguise." The Epopt, after passing through the ceremonial of exaltation, was said to have received Autopsia, or complete vision. Virgil declared that the secret of the Mysteries was the Unity of the Godhead, and Plato owned it to be "difficult to find the Creator of the Universe, and, when found, impossible to discover Him to all the world." Varro, in his work _Of Religions_, says that "there were many truths which it was inconvenient for the State to be generally known; and many things which, though false, it was expedient the people should believe, and that, therefore, the Greeks shut up their Mysteries in the silence of their sacred enclosures." The Mysteries declared that the future life was not the shadowy, weary existence which it had hitherto been supposed to be, but that through the rites of purification and sacrifices of a sacramental character man could secure a better hope for the future. Thus the Eleusinian Mysteries became the chief agent in the conversion of the Greek world from the Homeric view of Hades to a more hopeful belief as to man's state after death. Tully promulgated a law forbidding nocturnal sacrifices in which women were permitted to take part, but made an express exception in favour of the Eleusinian Mysteries, giving as his reason: "Athens hath produced many excellent, even divine inventions and applied them to the use of life, but she has given nothing better than those Mysteries by which we are drawn from an irrational and savage life and tamed, as it were, and broken to humanity. They are truly called _Initia_, for they are indeed the beginnings of a life of reason and virtue."
