fall about the middle of October,(172) and that was the Greek farmer’s great time for ploughing and sowing.(173) Hence we should expect him to make his offering of first-fruits to the Corn Goddess shortly before he ploughed and sowed, and this expectation is entirely confirmed by the date which we have inferred for the offering from the evidence of Theocritus. Thus the sacrifice of barley to Demeter in the autumn would seem to have been not so much a thank-offering as a bribe judiciously administered to her at the very moment of all the year when her services were most urgently wanted. (M39) When with the progress of civilisation a number of petty agricultural communities have merged into a single state dependent for its subsistence mainly on the cultivation of the ground, it commonly happens that, though every farmer continues to perform for himself the simple old rites designed to ensure the blessing of the gods on his crops, the government undertakes to celebrate similar, though more stately and elaborate, rites on behalf of the whole people, lest the neglect of public worship should draw down on the country the wrath of the offended deities. Hence it comes about that, for all their pomp and splendour, the national festivals of such states are often merely magnified and embellished copies of homely rites and uncouth observances carried out by rustics in the open fields, in barns, and on threshing-floors. In ancient Egypt the religion of Isis and Osiris furnishes examples of solemnities which have been thus raised from the humble rank of rural festivities to the dignity of national celebrations;(174) and in ancient Greece a like development may be traced in the religion of Demeter. If the Greek ploughman prayed to Demeter and Underground Zeus for a good crop before he put his hand to the plough in autumn, the authorities of the Athenian state celebrated about the same time and for the same purpose a public festival in honour of Demeter at Eleusis. It was called the Proerosia, which signifies “Before the Ploughing”; and as the festival was dedicated to her, Demeter herself bore the name of Proerosia. Tradition ran that once on a time the whole world was desolated by a famine, and that to remedy the evil the Pythian oracle bade the Athenians offer the sacrifice of the Proerosia on behalf of all men. They did so, and the famine ceased accordingly. Hence to testify their gratitude for the deliverance people sent the first-fruits of their harvest from all quarters to Athens.(175)
