Italy, however, needed peace as badly as the Goths needed a secure retreat. And when negotiations were opened it was seen that their success depended entirely upon this question of Placidia. A treaty was drawn up of friendship and alliance between the Goths and the empire. The services of Ataulfus were accepted against the barbarians who were harrying the provinces beyond the Alps, and the king, with Galla Placidia a willing captive, began his retreat from Campania into Gaul. His troops occupied the cities of Narbonne, Toulouse, and Bordeaux, and in spite of the protests and resistance of the harassed provincials soon extended their quarters from the Mediterranean to the Atlantic.

To hold the Goth to his friendship and to secure his absence from Italy nothing remained but to accord him the hand of Placidia; and in the year 414 at Narbonne their marriage was solemnised.[2]

[Footnote 2: Olympiodorus and Idatius say the marriage took place at Narbonne, but Jornandes, op cit. c. 31, asserts that it took place at Forli before Ataulfus left Italy. Perhaps there were two ceremonies, or perhaps the ceremony at Narbonne was but the celebration of an anniversary.]

With the retreat of the Goth and the treaty sealed by the marriage of Placidia, the sister of Honorius, and the Gothic king, Italy secured herself a peace and a repose which endured for some forty-two years, only broken by the raid of Heraclian from Africa in 413.

But Ataulfus did not long survive his marriage. Having crossed the Pyrenees and surprised in the name of Honorius the city of Barcelona, he was assassinated in the palace there, and in the tumult which followed, Singeric, the brother of his enemy and a stranger to the royal race, was hailed as king. This revolution made Placidia once more a fugitive, and we see the daughter of Theodosius "confounded among a crowd of vulgar captives, compelled to march on foot above twelve miles before the horse of a barbarian, the assassin of a husband whom Placidia loved and lamented." On the seventh day of his reign, however, Singeric was himself assassinated and Wallia, who then became king of the Goths, after repeated representations backed at last by the despatch of an army surrendered the princess to her brother in exchange for 600,000 measures of wheat.

That must have been a strange home-coming for Placidia. Bought and sold twice over, twice a fugitive, the companion of the rude Goth, she is the most pathetic figure in all that terrible fifth century, and never does she appear more pitiful than on her return from the camps and the triumphs of the barbarians to the decadent splendour and the corruption of the imperial court of Ravenna, and again as a captive, a prize, booty.

For the man who had been at the head of that army whose approach, real or supposed, had decided the Goths to deliver up the sister of the emperor was Constantius, her old lover, he who had delayed her marriage with Ataulfus and who now determined to marry her himself.

It was in 416 that Placidia returned to Ravenna. In the following year Honorius gave her to Constantius, then his colleague in the consular office for the second time. The marriage ceremony of very great splendour took place in Ravenna; and in the same year was born of that marriage Honoria, who was to offer herself to Attila, and in 419 Valentinian, one day to be emperor.

That marriage soon had the result Constantius had intended. In 421 Honorius was compelled to associate him with himself on the imperial throne and to give to Placidia the title of Augusta. The new emperor, however, survived his elevation to the throne but seven months and once more Placidia was a widow. Her life, never a happy one, if we except the few years in which she was the wife of Ataulfus, whom she seems really to have loved, became unbearable after the death of Constantius. At the mercy of her brother who was fast sinking, at the age of thirty-nine, into a vicious and idiotic senility, she, always a sincere Catholic in spite of her romantic marriage with the Arian Ataulfus, seems to have been forced into a horrible intimacy with him; at least we know that he obliged her to receive his obscene kisses, even in public, to the scandal and perhaps the amusement of that corrupt society. And then suddenly her brother's dreadful love seems to have turned to hate and she is a fugitive again with her two children at the court of her nephew Theodosius II. at Constantinople. In the very year of her flight Honorius died and the throne of the West was vacant.

It was filled by the obscure civil servant Joannes, the chief of the notaries, the creature of some palace intrigue. But such a choice could not be tolerated by Theodosius, who immediately confirmed Placidia in her title of Augusta, which had not before been recognised at Constantinople, and accepted Valentinian, whose title was Nobilissimus, as the heir to the western throne, giving him the title of Caesar. To suppress the usurper Joannes, Theodosius despatched an army to bring Placidia and her children to Ravenna. After a short campaign in northern Italy, by a miracle, according to the contemporary historian Socrates, the troops of Theodosius arrived before Ravenna. "The prayer of the pious emperor again prevailed. For an angel of God, under the semblance of a shepherd, undertook the guidance of Aspar and his troops, and led them through the lake near Ravenna. Now no one had ever been known to ford that lake before; but God then caused that to be possible which before had been impossible. But when they had crossed the lake, as if going over dry land, they found the gates of the city open and seized the tyrant Joannes."[1]
