http://it.wikipedia.org/wiki/Gennadio_Avieno Правда, если Вы спрашивали не об Авиене в общем, а как о потомке консула М-В-М-Корвина, то там обозначено как "вероятно".
У Бари с ссылкой на Сидония Аполлинария (Sidonius Apoll. Epp. I.9): "The Emperor, who was at Rome, sent Leo and two leading senators, Avienus and Trygetius, to negotiate with the invader. Trygetius had diplomatic experience; he had negotiated the treaty with Gaiseric in A.D. 435. Leo was an imposing figure, and the story gives him the credit for having persuaded Attila to retreat. He was supported by celestial beings; the apostles Peter and Paul are said to have appeared to Attila and by their threats terrified him into leaving the soil of Italy." (

У Эдварда Гиббона (тоже ссылается на Сидония Апполинария): "The Western emperor, with the senate and people of Rome, embraced the more salutary resolution of deprecating, by a solemn and suppliant embassy, the wrath of Attila. This important commission was accepted by Avienus, who, from his birth and riches, his consular dignity, the numerous train of his clients, and his personal abilities, held the first rank in the Roman senate. The specious and artful character of Avienus(60) was admirably qualified to conduct a negotiation either of public or private interest: his colleague Trigetius had exercised the Praetorian praefecture of Italy; and Leo, bishop of Rome, consented to expose his life for the safety of his flock."(

Письмо, где непосредственно говорится об Авиене - девятое по счету
Упоминание об Авиене есть разумеется, и в PLRE
Цитата такова: "But without disparagement to others, we found two consulars, Gennadius Avienus and Caecina Basilius, in enjoyment of a peculiar eminence, and conspicuous above the rest; if you leave out of the account the great military officers, these two members of the exalted order easily come next to the emperor himself. We found them both deserving of the highest admiration; but their characters were very different; what resemblance there was rested rather on inborn than acquired qualities" А строчкой ниже Сидоний пишет, что "There was a further reason for preferring the Decian to the Corvinian family.", т.е. относит Авиена к Корвинам, а Василия, соответственно, к Дециям, делая предпочтение последним.
Если не ошибаюсь, Вы говорите о Фл.Эннодии Мессале, консуле 506 г.?
