rendered them their dues in the shape of offerings of the ripe barley and wheat. Now we know that the Mysteries of Eleusis were celebrated every year, and accordingly, if I am right in interpreting them as essentially a dramatic representation of the annual vicissitudes of the corn performed for the purpose of quickening the seed, it becomes probable that in some form or another they were annually held at Eleusis long before the practice arose of celebrating games there every fourth or every second year. In short, the Eleusinian mysteries were in all probability far older than the Eleusinian games. How old they were we cannot even guess. But when we consider that the cultivation of barley and wheat, the two cereals specially associated with Demeter, appears to have been practised in prehistoric Europe from the Stone Age onwards,(274) we shall be disposed to admit that the annual performance of religious or magical rites at Eleusis for the purpose of ensuring good crops, whether by propitiating the Corn Goddess with offerings of first-fruits or by dramatically representing the sowing and the growth of the corn in mythical form, probably dates from an extremely remote antiquity. (M57) But in order to clear our ideas on this subject it is desirable to ascertain, if possible, the reason for holding the Eleusinian games at intervals of two or four years. The reason for holding a harvest festival and thanksgiving every year is obvious enough; but why hold games only every second or every fourth year? The reason for such limitations is by no means obvious on the face of them, especially if the growth of the crops is deemed dependent on the celebration. In order to find an answer to this question it may be well at the outset to confine our attention to the Great Eleusinian Games, which were celebrated only every fourth year. That these were the principal games appears not only from their name, but from the testimony of Aristotle, or at least of the author of _The Constitution of Athens_, who notices only the quadriennial or, as in accordance with Greek idiom he calls it, the penteteric celebration of the games.(275) Now the custom of holding games at intervals of four years was very common in Greece; to take only a few conspicuous examples the Olympic games at Olympia, the Pythian games at Delphi, the Panathenaic games at Athens, and the Eleutherian games at Plataea(276) were all celebrated at quadriennial or, as the Greeks called them, penteteric periods; and at a later time when Augustus instituted, or rather renewed on a more splendid scale, the games at Actium to commemorate his great victory, he followed a well-established Greek precedent by ordaining that they should be quadriennial.(277) Still later the emperor Hadrian instituted quadriennial games at Mantinea in honour of his dead favourite Antinous.(278) But in regard to the two greatest of all the Greek games, the Olympian and the
