The union of Poseidon and Demeter is thus explained by Mannhardt. As the waves of the sea are fancifully compared to horses, so a field of corn, waving in the breeze, may be said to represent the wedding of the sea-god and the corn-goddess. In any case the association of Poseidon, representing the fertilizing element of moisture, with Demeter, who causes the plants and seeds to grow, is quite natural, and seems to have been widespread.

In this wider sense Demeter is akin to Ge, with whom she has several epithets in common, and is sometimes identified with Rhea-Cybele; thus Pindar speaks of Demeter χαλκοκρότος (“brass-rattling”) , an epithet obviously more suitable to the Asiatic than to the Greek earth-goddess. Although the goddess of agriculture is naturally inclined to peace and averse from war, the memory of the time when her land was won and kept by the sword still lingers in the epithets χρυσάορος and ξιφηφόρος and in the name Triptolemus, which probably means “thrice fighter” rather than “thrice plougher.”

Demeter then returns to Olympus, but before her final departure from earth, in token of her gratitude, she instructs the rulers of Eleusis in the art of agriculture and in the solemnities and rites whereby she desires in future to be honoured.
Those who were initiated into the mysteries of Eleusis found a deep meaning in the myth, which was held to teach the principle of a future life, founded on the return of Persephone to the upper world, or rather on the process of nature by which seed sown in the ground must first die and rot before it can yield new life (see Mystery) .
