Decius was the son of
Caecina Decius Basilius, consul in 463, and brother of
Decius Marius Venantius Basilius (consul in 484), and Basilius (consul in 480, identified with
Caecina Decius Maximus Basilius); thus he was a member of the
gens Caecinia. 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. == Notes ==
