Bishop Eusebius, the chaplain of the Imperial family, as one may term him, would not mention such a circumstance in his “Life of Constantine,” even if he knew it to be true; but it is not quite accurate to say peremptorily that the bishop never mentions it. In the second book of his “Chronicle” (ad annum 310) we read that Constantine was “the son of Constantius by his concubine Helena.” We have no means of determining if these words were written by Eusebius or added by St. Jerome.[22] Even in the latter case it is a weighty testimony.
Another Christian historian of Jerome’s time, Orosius—who does not follow Zosimus, as Gibbon says, but precedes him—makes the same statement (c. xxv), and it is later repeated in the “Chronicle” of Cassiodorus. A writer of the generation after Constantine, commonly known as “Anonymus Valesii,” says (c. ii) that Constantine was “born of Helena, a very common [vilissima] woman, in the town of Naissus.” Zosimus, a century later, and a pagan critic of Constantine, says (ii. 8) that he was “born of a woman who was not respectable σεμνή and not legally married to Constantius,” and he later observes that Maxentius resented the raising to the throne of a man whose mother was “not a matron.” Finally, the early mediæval monk, Zonaras, says (“Annals,” xiii. i): “Some say that she was lawfully married to Constantius and divorced ... others that she was not a legitimate wife but a paramour.” The grave and weighty Eutropius, writing in the generation after Constantine, says that he was born of “a somewhat ambiguous [obscuriori] marriage.”
The Benedictines had an ample authority, both Christian and pagan, for their view, and only one argument is advanced in disproof of it by modern writers. Several of the historians tell us that, when Constantius was made Cæsar, he was compelled by the Emperor to “divorce” Helena, and, it is said, divorce implies marriage. The argument is hardly conclusive. When Eusebius (or Jerome) tells us that the Cæsars were compelled to dismiss their “wives,” he adds, on the same page, that Helena was not a wife, but a concubine. He means merely that Constantius was forced to dismiss Helena and wed the daughter of Maximian, and does not imply that any legal form of divorce was employed. It is quite open to us to interpret the other authority, Aurelius Victor, in the same way; and Zonaras, the only other writer who could be quoted, expressly leaves it open whether Helena was married or not. In any case, the single authority of Aurelius Victor cannot outweigh the others, and even his words do not necessarily imply a legal divorce on the part of both Cæsars.
But there is another aspect of the question, which is usually overlooked. Could there be a valid marriage between Helena and Constantius in Roman law? When we regard the subject from this point of view, we see that Constantius could not possibly have married Helena before the birth of Constantine, and, unless her legal condition was subsequently altered by a special enactment, their union could never become a valid marriage. As I have earlier observed, the strict and ancient forms of Roman marriage had fallen very generally out of use under the Emperors. They had had the effect of putting the wife under the despotic power of the husband, and Roman feeling in regard to the position of woman had entirely changed. Looser forms of marriage, which evaded the older tyranny of the husband, were generally employed and legally recognized. If a man and woman lived together uninterruptedly for twelve months—without three nights’ interruption—their union might become a valid marriage. Below this was the legally recognized concubine. The ease with which Christian writers admitted that Helena was a concubine is due to the fact that the Church, as well as the law, permitted a concubine, if a man had no wife. As late as the year 400, the important provincial Council of Toledo decided that such a man and his concubine were to be admitted to communion. St. Augustine, we shall see, went even further. Below these, again, were the ordinary paramours, the mistresses of a month or the playthings of an hour, which Stoic and Christian equally condemned.
The real question we have to decide is, therefore, whether the long association of Constantius and Helena could ever be recognized as a valid marriage in Roman law. That they went through any form of marriage in 273 could only occur to a writer who knows nothing of Roman law or practice. A young officer, taking a girl from a tavern in a small provincial town on his route, would not dream of any such ceremony; and no ceremony would have been valid in Roman law. Whatever the legal condition of Constantius was, Helena was, to Roman law, a barbarian, or peregrina, and could not contract a valid marriage.[23] We need little acquaintance with Roman life to imagine what happened. Constantius felt for the young woman he found at the country inn a more tender sentiment than that usually entertained by the young centurion or tribune on travel, and he took her to live with him. I do not see how this relation ever could become a valid marriage, nor is there any clear proof that they were ever legally divorced. At the most, it remains “a questionable marriage,” as Eutropius calls it, and it began as a free union.
From Nicomedia Constantius’s troop seems to have passed, possibly after sharing Aurelian’s triumph at Rome, to Thrace, where Constantine is said to have been born in the year 274. Helena narrowly missed the dignity of Empress a few years later, as Carus had some disposition to leave the purple to Constantius. The mother of Constantius had been a niece of the Emperor Claudius, and his father was one of the chief nobles of Dardania. But the accession of Carinus dispelled this hope, and Helena followed her husband from province to province, and grade to grade, until, in 292, he was selected for the lofty position of Cæsar of the West. But with the purple came a command that he must dismiss his concubine, and marry the stepdaughter of Maximian, Flavia Maximiana Theodora. From that date until the year of her son’s brilliant triumph Helena passes into complete obscurity.
Meantime other Empresses occupy the pages of the historian. Theodora, of whom we have just spoken, is one of those Empresses whose propriety of conduct and mediocrity of person have not attracted the lamp of the historian. She was the daughter of Eutropia, the Syrian wife of Maximian, by a former husband. Three boys and three girls came of her union with Constantius, and she seems to have been a worthy consort of that judicious and happy ruler. The full Imperial title passed to them when Maximian abdicated in 305, and the handsome and spirited Constantine joined them at Gessoriacum (Boulogne), after his romantic flight from Nicomedia, in that or the following year. They crossed to Britain, and suppressed a rebellion that was in progress. But Constantius died at Eboracum (York) in the summer of 306, and the unambitious Theodora passes from our sight.
Constantius had, with a last display of prudence, preferred his eldest son to the legitimate children of his wife, and probably little money needed to be distributed among the legions to ensure that they should recognize his superiority. Constantine was then in his early manhood, a commanding and graceful figure, in the finest phase of his character, and the troops followed him with alacrity from the cold mists of north Britain to more genial and more cultivated Gaul. From Gaul the young Cæsar watched with close interest the quarrels in which his colleagues prepared to devour each other. In February of 307 he heard that Severus had opened his veins, and left the purple in the hands of the crafty Maximian and his son Maxentius. Within a few weeks Maximian was in Gaul, seeking an alliance with Constantine. He brought with him his pretty and charming daughter, Fausta, and presently she was married at Arles, with great pomp, to Constantine, the stepson of her half-sister. The old man returned to his intrigues in Italy, from which he was shortly ejected by his son: Galerius expelled him from Illyricum, where he had taken shelter; and he returned to the court of his son-in-law in Gaul.
The portrait-bust of Maximian might be confused with that of a modern pugilist, but he had, in addition to strength and ambition, a restless disposition to intrigue. To rust in a court full of women—for we may confidently place in the court of Constantine his wife, mother, stepmother, mother-in-law, and three young half-sisters, if not also his concubine—was to him an intolerable experience, and he took the first opportunity of enlivening his surroundings. An inroad of the barbarians in the north drew away the young Emperor with much of his army, and Maximian rebelled. He gave out a report that Constantine was dead, emptied the treasury into the hands of the soldiers, and assumed the purple mantle once more. But Constantine returned with the stride of a giant, and Maximian shut himself in Marseilles, which was presently surrendered. The aged intriguer returned to the palace, tried to corrupt the loyalty of his daughter, and brought upon himself the punishment of his crimes.
It is a peculiarity of the time that, the more remote an historian is from an event, the more he knows about it. Eutropius and Zosimus merely know that Fausta revealed her father’s plots to her husband; Zonaras, of the twelfth century, is able to tell us the whole story. Maximian, he says, persuaded his daughter to have the guards removed from the Imperial chamber at night. Then, telling the night-attendants that he wished to relate to Constantine a remarkable dream he had had, he entered the chamber and plunged his dagger into the sleeping figure on the bed. Rushing out to announce the fall of the tyrant, however, he found himself in face of Constantine, Fausta, and the guards. Fausta had been true to her husband, and it was “a vile eunuch” that Maximian had slain in the Emperor’s bed. Whatever truth there may be in this romance, we may accept the statement that Fausta betrayed his plots, and Maximian came to the end of his career. Zosimus sends him into exile, and makes him die a natural death at Tarsus. Lactantius, with a stronger sense of propriety, tells us that he strangled himself, and it is the general belief that Constantine did not permit him to leave Gaul alive.
