Decius Marius Venantius Basilius

Decius Marius Venantius Basilius (floruit 484) was a Roman official under Odoacer's rule.

Inscription erected by Basilius at the Colosseum in Rome, one of the two copies produced in occasion of a restoration funded by Basilius after the damages of an earthquake (CIL VI, 1716).


He was the son of Caecina Decius Basilius and the brother of Caecina Mavortius Basilius Decius and Caecina Decius Maximus Basilius, all Roman Consuls. Basilius Venantius iunior, Consul in 508, was probably his son.

Basilius was Praefectus urbi and Consul in 484, with Theoderic the Great as colleague.

He financed the restoration of the damages made by an earthquake to the Colosseum of Rome; two inscriptions are still extant, reading (CIL VI, 1716 b and c):
