Thus it appears that the right to marry a girl, and especially a princess, has often been conferred as a prize in an athletic contest. There would be no reason, therefore, for surprise if the Roman kings, before bestowing their daughters in marriage, should have resorted to this ancient mode of testing the personal qualities of their future sons-in-law and successors. If my theory is correct, the Roman king and queen personated Jupiter and his divine consort, and in the character of these divinities went through the annual ceremony of a sacred marriage for the purpose of causing the crops to grow and men and cattle to be fruitful and multiply. Thus they did what in more northern lands we may suppose the King and Queen of May were believed to do in days of old. Now we have seen that the right to play the part of the King of May and to wed the Queen of May has sometimes been determined by an athletic contest, particularly by a race. This may have been a relic of an old marriage custom of the sort we have examined, a custom designed to test the fitness of a candidate for matrimony. Such a test might reasonably be applied with peculiar rigour to the king in order to ensure that no personal defect should incapacitate him for the performance of those sacred rites and ceremonies on which, even more than on the despatch of his civil and military duties, the safety and prosperity of the community were believed to depend. And it would be natural to require of him that from time to time he should submit himself afresh to the same ordeal for the sake of publicly demonstrating that he was still equal to the discharge of his high calling. A relic of that test perhaps survived in the ceremony known as the Flight of the King (_regifugium_), which continued to be annually observed at Rome down to imperial times. On the twenty-fourth day of February a sacrifice used to be offered in the Comitium, and when it was over the King of the Sacred Rites fled from the Forum. We may conjecture that the Flight of the King was originally a race for an annual kingship, which may have been awarded as a prize to the fleetest runner. At the end of the year the king might run again for a second term of office; and so on, until he was defeated and deposed or perhaps slain. In this way what had once been a race would tend to assume the character of a flight and a pursuit. The king would be given a start; he ran and his competitors ran after him, and if he were overtaken he had to yield the crown and perhaps his life to the lightest of foot among them. In time a man of masterful character might succeed in seating himself permanently on the throne and reducing the annual race or flight to the empty form which it seems always to have been within historical times. The rite was sometimes interpreted as a commemoration of the expulsion of the kings from Rome; but this appears to have been a mere afterthought devised to explain a ceremony of which the old meaning was forgotten.
