He had four sons, all of whom attained consular rank: Albinus in 493 (presumably the first consul nominated by Theodoric the Great), Avienus in 501, Theodorus in 505, and Inportunus in 509.

As leader of the Roman Senate and chief minister to king Odoacer, and patron to the Greens, Basilius was one of the most powerful men in post-Imperial Rome.

[3] As a result, Basilius played a major role in the papal election of 483, being the beneficiary of an admonitio issued by Pope Simplicius that gave him veto power over the election of Simplicius' successor.

When it was clear Simplicius was on his deathbed, Basilius convened a meeting of the Roman Senate, the local clergy, and leading local bishops at the Imperial Mausoleum to elect the next Pope, Felix.

[4] The proceedings of a Roman synod of 501 indicate that he was dead by that date, and a passage of Cassiodorus shows that his death occurred before his sons reached adulthood, leaving their mother in charge of running the household.
