Olybrius emperor of the West. A.D. 472, March 23 The senator Olybrius, of the Anieian family, might esteem himself the lawful heir of the Western empire. He had married Placidia, the younger daughter of Valentinian, after she was restored by Genseric; who still detained her sister Eudoxia, as the wife, or rather as the captive, of his son. The king of the Vandals supported, by threats and solicitations, the fair pretensions of his Roman ally; and assigned, as one of the motives of the war, the refusal of the senate and people to acknowledge their lawful prince, and the unworthy preference which they had given to a stranger. The friendship of the public enemy might render Olybrius still more unpopular to the Italians; but, when Ricimer meditated the ruin of the emperor Anthemius, he tempted with the offer of a diadem the candidate who could justify his rebellion by an illustrious name and a royal alliance. The husband of Placidia, who, like most of his ancestors, had been invested with the consular dignity, might have continued to enjoy a secure and splendid fortune in the peaceful residence of Constantinople; nor does he appear to have been tormented by such a genius as cannot be amused or occupied unless by the administration of an empire. Yet Olybrius yielded to the importunities of his friends, perhaps of his wife; rashly plunged into the dangers and calamities of a civil war; and, with the secret connivance of the emperor Leo, accepted the Italian purple, which was bestowed and resumed at the capricious will of a Barbarian. He landed without obstacle (for Genseric was master of the sea) either at Ravenna or the port of Ostia, and immediately proceeded to the camp of Ricimer, where he was received as the sovereign of the Western world. 
Sack of Rome, and death of Anthemius. A.D. 472, July 11 The patrician, who had extended his posts from the Anio to the Milvian bridge, already possessed two quarters of Rome, the Vatican and the Janiculum, which are separated by the Tiber from the rest of the city;  and it may be conjectured that an

- The hostile appearance of Olybrius is fixed (notwithstanding the opinion of Pagi) by the duration of his reign. The secret connivance of Leo is acknowledged by Theophanes and the Paschal Chronicle. We are ignorant of his motives; but in this obscure period our ignorance extends to the most public and important facts.
- Of the fourteen regions, or quarters, into which Rome was divided by Augustus, only one, the Janiculum, lay on the Tuscan side of the Tiber. But, in the fifth century, the Vatican suburb formed a considerable city; and in the eccle-
