Caecina Mavortius Basilius Decius
Decius was the son of Caecina Decius Basilius, consul in 463, and brother of Decius Marius Venantius Basilius (consul in 484), and Basilius iunior (consul in 480, identified with Caecina Decius Maximus Basilius); thus he was member of the gens Caecina. He had a son, Vettius Agorius Basilius Mavortius, who was consul in 527.
Decius returned to favor under the rule of Theodoric the Great, by reclaiming a portion of the Pontine Marshes at his own expense. He was praised for this in a letter signed by Theodoric, and Decius set up an inscription at Terracina stating this was done by the command of king Theodoric. Around 510, Decius was one of five senators appointed to investigate charges that the vir inlustris Basilius and Praetextatus had practiced black magic.
