is extremely improbable and altogether unproven.  However that may be, after one of his three sieges of Rome, Alaric carried Galla Placidia off as a hostage.  He seems, according to Zosimus, to have treated her with courtesy and even with an exaggerated reverence, as the sister of the emperor and the daughter of Theodosius, but she was compelled to follow in his train and to see the ruin of Lucania and Calabria.  For, as a matter of fact and reality, Galla Placidia was the one hope of the Goths and this became obvious after the death of Alaric.

[Footnote 1:  Zosimus, v. 38.  Zosimus was a pagan.  Placidia was a devout and enthusiastic Catholic.]

The Gothic army was in a sort of trap; it could not return without the consent of Ravenna, and if it were compelled to remain in Italy it was only a question of time till it should be crushed or gradually wasted away.  It is probable that Alaric was aware of this; it is certain that it was well appreciated by his successor Ataulfus.  He saw that his one chance of coming to terms with the empire lay in his possession of Galla Placidia.  Moreover, Italy and Rome had worked in the mind and the spirit of this man the extraordinary change that was to declare itself in the soul of almost every barbarian who came to ravage them.  He began dimly to understand what the empire was.  He felt ashamed of his own rudeness and of the barbarism of his people.  Years afterwards he related to a citizen of Narbonne, who in his turn repeated the confession to S. Jerome in Palestine in the presence of the historian Orosius, the curious “conversion” that Italy had worked in his heart.  “In the full confidence of valour and victory,” said Ataulfus, “I once aspired to change the face of the universe; to obliterate the name of Rome; to erect on its ruins the dominion of the Goths; and to acquire, like Augustus, the immortal fame of the founder of a new empire.  By repeated experiments I was gradually convinced that laws are essentially necessary to maintain and regulate a well constituted state, and that the fierce untractable humour of the Goths was incapable of bearing the salutary yoke of laws and civil government.  From that moment I proposed to myself a different object of glory and ambition; and it is now my sincere wish that the gratitude of future ages should acknowledge the merit of a stranger who employed the sword of the Goths not to subvert but to restore and maintain the prosperity of the Roman Empire."[1]

[Footnote 1:  Orosius, vii. c. 43.  Gibbon, c. xxxi.]

With this change in his heart and the necessity of securing a retreat upon the best terms he could arrange, Ataulfus looked on Placidia his captive and found her perhaps fair, certainly a prize almost beyond the dreams of a barbarian.  He aspired to marry her, and she does not seem to have been unready to grant him her hand.  Doubtless she had been treated by Alaric and his successor with an extraordinary respect not displeasing to so royal a lady, and Ataulfus, though not so tall as Alaric, was both shapely and noble.[1] There seems indeed to have been but one obstacle to this match.  This was the ambition of Constantius, the new minister of Honorius, who wished to make his position secure by marrying Placidia himself.
