(M52) However, there is no sufficient ground for identifying the Ancestral Contest of the Eleusinian games with the Ancestral Contest of the Threshing-festival at Eleusis, and accordingly the connexion of the games with the corn-harvest and with the corn-hero Triptolemus must so far remain uncertain. But a clear trace of such a connexion may be seen in the custom of rewarding the victors in the Eleusinian games with measures of barley; in the official Athenian inscription of 329 B.C., which contains the accounts of the superintendents of Eleusis and the Treasurers of the Two Goddesses, the amounts of corn handed over by these officers to the priests and priestesses for the purposes of the games is exactly specified.(261) This of itself is sufficient to prove that the Eleusinian games were closely connected with the worship of Demeter and Persephone. The grain thus distributed in prizes was probably reaped on the Rarian plain near Eleusis, where according to the legend Triptolemus sowed the first corn.(262) Certainly we know that the barley grown on that plain was used in sacrifices and for the baking of the sacrificial cakes,(263) from which we may reasonably infer that the prizes of barley, to which no doubt a certain sanctity attached in the popular mind, were brought from the same holy fields. So sacred was the Rarian plain that no dead body was allowed to defile it. When such a pollution accidentally took place, it was expiated by the sacrifice of a pig,(264) the usual victim employed in Greek purificatory rites.
