according to the prevalent tradition it was to Triptolemus that Demeter first revealed the secret of the corn, and it was he whom she sent out as an itinerant missionary to impart the beneficent discovery of the cereals to all mankind and to teach them to sow the seed.(254) On monuments of art, especially in vase-paintings, he is constantly represented along with Demeter in this capacity, holding corn-stalks in his hand and sitting in his car, which is sometimes winged and sometimes drawn by dragons, and from which he is said to have sowed the seed down on the whole world as he sped through the air.(255) At Eleusis victims bought with the first-fruits of the wheat and barley were sacrificed to him as well as to Demeter and Persephone.(256) In short, if we may judge from the combined testimony of Greek literature and art, Triptolemus was the corn-hero first and foremost. Even beyond the limits of the Greek world, all men, we are told, founded sanctuaries and erected altars in his honour because he had bestowed on them the gift of the corn.(257) His very name has been plausibly explained both in ancient and modern times as “Thrice-ploughed” with reference to the Greek custom of ploughing the land thrice a year,(258) and the derivation is said to be on philological principles free from objection.(259) In fact it would seem as if Triptolemus, like Demeter and Persephone themselves, were a purely mythical being, an embodiment of the conception of the first sower. At all events in the local Eleusinian legend, according to an eminent scholar, who has paid special attention to Attic genealogy, “Triptolemus does not, like his comrade Eumolpus or other founders of Eleusinian priestly families, continue his kind, but without leaving offspring who might perpetuate his priestly office, he is removed from the scene of his beneficent activity. As he appeared, so he vanishes again from the legend, after he has fulfilled his divine mission.”(260)
