which seems to have been overlooked by previous enquirers, deserves to be taken into account. It is a corollary from the shifting dates of the lunar months that the official Greek calendar, in spite of its appearance of exactness, really furnished the ancient farmer with little trustworthy guidance as to the proper seasons for conducting the various operations of agriculture; and he was well advised in trusting to various natural timekeepers, such as the rising and setting of the constellations, the arrival and departure of the migratory birds, the flowering of certain plants,(184) the ripening of fruits, and the setting in of the rains, rather than to the fallacious indications of the public calendar. It is by natural timekeepers, and not by calendar months, that Hesiod determines the seasons of the farmer’s year in the poem which is the oldest existing treatise on husbandry.(185) (M41) Just as the ploughman’s prayer to Demeter, before he drove the share through the clods of the field, was taken up and reverberated, so to say, with a great volume of sound in the public prayers which the Athenian state annually offered to the goddess before the ploughing on behalf of the whole world, so the simple first-fruits of barley, presented to the rustic Demeter under the dappled shade of rustling poplars and elms on the threshing-floor in Cos, were repeated year by year on a grander scale in the first-fruits of the barley and wheat harvest, which were presented to the Corn Mother and the Corn Maiden at Eleusis, not merely by every husbandman in Attica, but by all the allies and subjects of Athens far and near, and even by many free Greek communities beyond the sea. The reason why year by year these offerings of grain poured from far countries into the public granaries at Eleusis, was the widespread belief that the gift of corn had been first bestowed by Demeter on the Athenians and afterwards disseminated by them among all mankind through the agency of Triptolemus, who travelled over the world in his dragon-drawn car teaching all peoples to plough the earth and to sow the seed.(186) In the fifth century before our era the legend was celebrated by Sophocles in a play called _Triptolemus_, in which he represented Demeter instructing the hero to carry the seed of the fruits which she had bestowed on men to all the coasts of Southern Italy,(187) from which we may infer that the cities of Magna Graecia were among the number of those that sent the thank-offering of barley and wheat every year to Athens. Again, in the fourth century before our era Xenophon represents Callias, the braggart Eleusinian Torchbearer, addressing the Lacedaemonians in a set speech, in which he declared that “Our ancestor Triptolemus is said to have bestowed the seed of Demeter’s corn on the Peloponese before any other land. How then,” he asked with pathetic earnestness, “can it be right that you should come to ravage the corn of the men from whom you received the seed?”(188) Again,
