Rufius Gennadius Probus Orestes
Rufius Gennadius Probus Orestes was a Roman aristocrat. He was appointed consul of the Senate for the year 530, which he held alongside Flavius Lampadius. Johannes Sundwall believed Orestes was the son of Rufius Magnus Faustus Avienus, the consul of 502, which is supported by more recent writers.
On 17 December 546 Orestes was in Rome when the Ostrogothic King Totila captured the city. Orestes, Anicius Olybrius, Anicius Maximus, and other patricii sought refuge in Old St. Peter's Basilica. He afterwards joined a group of refugees who followed the Byzantine army as far as Portus. The following year, when some Byzantine soldiers were patrolling in Campania and encountered captured senators, who were freed and afterward sent to Sicily, he was left behind due to a lack of horses. Orestes was still a prisoner of the Visigoths when Narses conquered Rome in 552; the senators were preparing to return to Rome, but, enraged by the death of Totila, the Goths who guarded them killed them all.
