service against the tyrants and Barbarians who infested the provinces beyond the Alps.  Adolphus, assuming the character of a Roman general, directed his march from the extremity of Campania to the southern provinces of Gaul.  His troops, either by force or agreement, immediately occupied the cities of Narbonne, Toulouse, and Bordeaux; and though they were repulsed by Count Boniface from the walls of Marseilles, they soon extended their quarters from the Mediterranean to the ocean.  The oppressed provincials might exclaim that the miserable remnant which the enemy had spared was cruelly ravished by their pretended allies; yet some specious colors were not wanting to palliate, or justify, the violence of the Goths.  The cities of Gaul, which they attacked, might perhaps be considered as in a state of rebellion against the government of Honorius; the articles of the treaty or the secret instructions of the court might sometimes be alleged in favor of the seeming usurpations of Adolphus; and the guilt of any irregular, unsuccessful act of hostility might always be imputed, with an appearance of truth, to the ungovernable spirit of a Barbarian host, impatient of peace or discipline.  The luxury of Italy had been less effectual to soften the temper than to relax the courage of the Goths; and they had imbibed the vices, without imitating the arts and institutions, of civilized society.

The professions of Adolphus were probably sincere, and his attachment to the cause of the republic was secured by the ascendant which a Roman princess had acquired over the heart and understanding of the Barbarian king.  Placidia, the daughter of the great Theodosius, and of Galla, his second wife, had received a royal education in the palace of Constantinople; but the eventful story of her life is connected with the revolutions which agitated the Western Empire under the reign of her brother Honorius.  When Rome was first invested by the arms of Alaric, Placidia, who was then about twenty years of age, resided in the city; and her ready consent to the death of her cousin Serena has a cruel and ungrateful appearance, which, according to the circumstances of the action, may be aggravated, or excused, by the consideration of her tender age.  The victorious Barbarians detained, either as a hostage or a captive, the sister of Honorius; but, while she was exposed to the disgrace of following round Italy the motions of a Gothic camp, she experienced, however, a decent and respectful treatment.  The authority of Jornandes, who praises the beauty of Placidia, may perhaps be counterbalanced by the silence, the expressive silence, of her flatterers; yet the splendor of her birth, the bloom of youth, the elegance of manners, and the dexterous insinuation which she condescended to employ, made a deep impression on the mind of Adolphus, and the Gothic King aspired to call himself the brother of the Emperor.  The ministers of Honorius rejected with disdain the proposal of an alliance so injurious
