At Athens, as at Rome, we find traces of succession to the throne by marriage with a royal princess; for two of the most ancient kings of Athens, namely Cecrops and Amphictyon, are said to have married the daughters of their predecessors. This tradition is to a certain extent confirmed by evidence, pointing to the conclusion that at Athens male kinship was preceded by female kinship.

Further, if I am right in supposing that in ancient Latium the royal families kept their daughters at home and sent forth their sons to marry princesses and reign among their wives’ people, it will follow that the male descendants would reign in successive generations over different kingdoms. Now this seems to have happened both in ancient Greece and in ancient Sweden; from which we may legitimately infer that it was a custom practised by more than one branch of the Aryan stock in Europe. Many Greek traditions relate how a prince left his native land, and going to a far country married the king’s daughter and succeeded to the kingdom. Various reasons are assigned by ancient Greek writers for these migrations of the princes. A common one is that the king’s son had been banished for murder. This would explain very well why he fled his own land, but it is no reason at all why he should become king of another. We may suspect that such reasons are afterthoughts devised by writers, who, accustomed to the rule that a son should succeed to his father’s property and kingdom, were hard put to it to account for so many traditions of kings’ sons who quitted the land of their birth to reign over a foreign kingdom. In Scandinavian tradition we meet with traces of similar customs. For we read of daughters’ husbands who received a share of the kingdoms of their royal fathers-in-law, even when these fathers-in-law had sons of their own; in particular, during the five generations which preceded Harold the Fair-haired, male members of the Ynglingar family, which is said to have come from Sweden, are reported in the Heimskringla or Sagas of the Norwegian Kings to have obtained at least six provinces in Norway by marriage with the daughters of the local kings.

Thus it would seem that among some Aryan peoples, at a certain stage of their social evolution, it has been customary to regard women and not men as the channels in which royal blood flows, and to bestow the kingdom in each successive generation on a man of another family, and often of another country, who marries one of the princesses and reigns over his wife’s people. A common type of popular tale, which relates how an adventurer, coming to a strange land, wins the hand of the king’s daughter and with her the half or the whole of the kingdom, may well be a reminiscence of a real custom.

Where usages and ideas of this sort prevail, it is obvious that the kingship is merely an appanage of marriage with a woman of the blood royal. The old Danish historian Saxo Grammaticus puts this view of the kingship very clearly in the mouth of Hermutrude, a legendary queen of Scotland. “Indeed she was a queen,” says Hermutrude, “and but that her sex gainsaid it, might be deemed a king; nay (and this is yet truer), whomsoever she thought worthy of her bed was at once a king, and she yielded her kingdom with herself. Thus her sceptre and her hand went together.” The statement is all the more significant because it appears to reflect the actual practice of the Pictish kings. We know from the testimony of Bede that, whenever a doubt arose as to the succession, the Picts chose their kings from the female rather than the male line.

The personal qualities which recommended a man for a royal alliance and succession to the throne would naturally vary according to the popular ideas of the time and the character of the king or his substitute, but it is reasonable to suppose that among them in early society physical strength and beauty would hold a prominent place.

Sometimes apparently the right to the hand of the princess and to the throne has been determined by a race. The Alitemnian Libyans awarded the kingdom to the fleetest runner. Amongst the old Prussians, candidates for nobility raced on horseback to the king, and the one who reached him first was ennobled. According to tradition the earliest games at Olympia were held by Endymion, who set his sons to run a race for the kingdom. His tomb was said to be at the point of the racecourse from which the runners started. The famous story of Pelops and Hippodamia is perhaps only another version of the legend that the first races at Olympia were run for no less a prize than a kingdom.

These traditions may very well reflect a real custom of racing for a bride, for such a custom appears to have prevailed among various peoples, though in practice it has degenerated into a mere form or pretence. Thus “there is one race, called the ‘Love Chase,’ which may be considered a part of the form of marriage among the Kirghiz. In this the bride, armed with a formidable whip, mounts a fleet horse, and is pursued by all the young men who make any pretensions to her hand. She will be given as a prize to the one who catches her, but she has the right, besides urging on her horse to the utmost, to use her whip, often with no mean force, to keep off those lovers who are unwelcome to her, and she will probably favour the one whom she has already chosen in her heart.” The race for the bride is found also among the Koryaks of North-eastern Asia. It takes place in a large tent, round which many separate compartments called pologs are arranged in a continuous circle. The girl gets a start and is clear of the marriage if she can run through all the compartments without being caught by the bridegroom. The women of the encampment place every obstacle in the man’s way, tripping him up, belabouring him with switches, and so forth, so that he has little chance of succeeding unless the girl wishes it and waits for him. Similar customs appear to have been practised by all the Teutonic peoples; for the German, Anglo-Saxon, and Norse languages possess in common a word for marriage which means simply bride-race. Moreover, traces of the custom survived into modern times.

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. It is far more likely that in acting thus the King of the Sacred Rites was merely keeping up an ancient custom which in the regal period had been annually observed by his predecessors the kings. What the original intention of the rite may have been must probably always remain more or less a matter of conjecture. The present explanation is suggested with a full sense of the difficulty and obscurity in which the subject is involved.

Thus if my theory is correct, the yearly flight of the Roman king was a relic of a time when the kingship was an annual office awarded, along with the hand of a princess, to the victorious athlete or gladiator, who thereafter figured along with his bride as a god and goddess at a sacred marriage designed to ensure the fertility of the earth by homoeopathic magic. If I am right in supposing that in very early times the old Latin kings personated a god and were regularly put to death in that character, we can better understand the mysterious or violent ends to which so many of them are said to have come. We have seen that, according to tradition, one of the kings of Alba was killed by a thunderbolt for impiously mimicking the thunder of Jupiter. Romulus is said to have vanished mysteriously like Aeneas, or to have been cut to pieces by the patricians whom he had offended, and the seventh of July, the day on which he perished, was a festival which bore some resemblance to the Saturnalia. For on that day the female slaves were allowed to take certain remarkable liberties. They dressed up as free women in the attire of matrons and maids, and in this guise they went forth from the city, scoffed and jeered at all whom they met, and engaged among themselves in a fight, striking and throwing stones at each other. Another Roman king who perished by violence was Tatius, the Sabine colleague of Romulus. It is said that he was at Lavinium offering a public sacrifice to the ancestral gods, when some men, to whom he had given umbrage, despatched him with the sacrificial knives and spits which they had snatched from the altar. The occasion and the manner of his death suggest that the slaughter may have been a sacrifice rather than an assassination. Again, Tullus Hostilius, the successor of Numa, was commonly said to have been killed by lightning, but many held that he was murdered at the instigation of Ancus Marcius, who reigned after him. Speaking of the more or less mythical Numa, the type of the priestly king, Plutarch observes that “his fame was enhanced by the fortunes of the later kings. For of the five who reigned after him the last was deposed and ended his life in exile, and of the remaining four not one died a natural death; for three of them were assassinated and Tullus Hostilius was consumed by thunderbolts.”

These legends of the violent ends of the Roman kings suggest that the contest by which they gained the throne may sometimes have been a mortal combat rather than a race. If that were so, the analogy which we have traced between Rome and Nemi would be still closer. At both places the sacred kings, the living representatives of the godhead, would thus be liable to suffer deposition and death at the hand of any resolute man who could prove his divine right to the holy office by the strong arm and the sharp sword. It would not be surprising if among the early Latins the claim to the kingdom should often have been settled by single combat; for down to historical times the Umbrians regularly submitted their private disputes to the ordeal of battle, and he who cut his adversary’s throat was thought thereby to have proved the justice of his cause beyond the reach of cavil.
