Bassianus

Bassianus (died 316 AD) was a Roman senator, whom the Emperor Constantine I arranged to marry his half-sister, Anastasia. According to the Anonymus Valesianus, a Latin chronicle composed during late antiquity, Bassianus was accused of plotting against the throne and was executed by Constantine. and Bassianus arrested and put to death. Constantine asked Licinius to hand him Senecio, but Licinius refused and overthrew his colleague's statues at Emona, on the border between the two spheres of influence; these events led to the outbreak of hostilities between Constantine and Licinius, an episode of civil war known as the bellum Cibalense.

Recent prosopographical studies suggest that Bassianus and Senecio were members of the families of Anicii and of Nummii Albini Seneciones.
