Serenianus

Serenianus (died in Lydia, 366) was an officer of the Roman Empire, involved in the death of Caesar Constantius Gallus and in the usurpation of Procopius.

Serenianus was born in Pannonia. attended at the court of Roman Emperor Constantius II (337-361). It is known that he had been a former general, in charge of the defence of Phoenicia, whose laxity had been the reason for the devastation of the city of Celsein. He was put under trial for treason: he had sent one of his men with an enchanted hat to ask oracles on the Emperor's life. However, even if the charge was demonstrated, he was declared not guilty, thanks to his friends.

In 354 he was sent to Pula, where Caesar Constantius Gallus was under trial for treason, to tell the prisoner that he had been condemned to death; then, together with Apodemius and Pentadius, he executed the Caesar.

In 364, Emperor Valentinian I proclaimed his brother Valens co-emperor.The two rulers divided among themselves the army and the officers. In this occasion, Serenianus, who had been returned to the reserve for long time, entered at Valens' service as comes domesticorum ("commander of the imperial bodyguard").

In 366 he was killed by Marcellus, protector of usurper Procopius, who, in 365, rebelled against Emperor Valens. The story is told differently by the two sources survived, Ammianus Marcellinus and Zosimus.
