Olybrius

[3] Olybrius married Placidia, younger daughter of western augustus Valentinian III (r. 425–455) and his wife Licinia Eudoxia, thus creating a bond between a member of the senatorial aristocracy and the conjoined Valentinianic–Theodosian dynasties.

The year of their wedding is not recorded, although the historian Priscus implies it took place before the Vandals under Gaiseric's sack of Rome (June 2–16, 455).

[7] The following year, Valentinian was killed by some soldiers who had served under Aetius, probably instigated by the patricius Petronius Maximus, who succeeded to the throne.

Petronius, who was a high-ranking imperial officer and a member of a family belonging to the senatorial aristocracy, married the augusta Licinia Eudoxia, widow of Valentinian.

The Vandals, led by King Gaiseric, took advantage of the confusion and weakness of the Western Empire in the wake of Valentinian's turbulent succession, moving into Italy and sacking Rome in June 455.

[9] On the other hand, the 6th-century chronicler Evagrius Scholasticus writes that Olybrius had fled Rome on the approach of Gaiseric's army.

Therefore, Gaiseric freed Licinia Eudoxia (fulfilling Daniel's prophesy) and her daughter Placidia (Olybrius' wife), but he did not cease his raids on Italy's coasts.

Olybrius' association with Gaiseric did not harm his career, however, as the Eastern court chose him for the high honour of the consulate in 464.

Leo suspected that Olybrius favored the Vandal king, however, and would secretly take his side and betray the suspicious Emperor.

What other reason could there be, Bury asks, then answers his own rhetorical question: "the facts that Anthemius was Leo's chosen candidate, his filius, and that Olybrius was the friend of his foe Genseric, are a strong counter-argument.

[b] It is also noteworthy that Olybrius is depicted on his coins without helm and spear, common symbols on his predecessors' coinage, suggesting he had little interest in military matters.

The story told in the opera is quite different from the real one, despite the fact that Zeno claimed to use several historical sources (Evagrius Scholasticus l.2.c.7, Procopius of Caesarea, Historia Vandalorum, l.1, Paul the Deacon, vi): Ricimer captures Rome, frees his sister Teodolinda and enslaves Placidia, daughter of Valentinian III; a little later, Olybrius frees Rome and Placidia, and marries her.

Gaiseric sacks Rome , by Karl Briullov . After the sack of Rome (455) , the Vandals took Licinia Eudoxia and her two daughters, among which also Olybrius' wife Placidia , to Africa; at that time Olybrius was in Constantinople.
