About Lucillianus
Lucillianus ( 358–363 AD) was a Roman military commander during the emperor Julian's disastrous expedition against Sasanian Empire in 363.
Harries identifies Lucillianus as one of the officials whom the emperor Constantius II sent in 358 to the court of his cousin Julian, then ruling as the emperor's deputy (Caesar) in Gaul, to serve as his adviser and keep watch over him.

Lucillianus was present at the meeting between Julian and Saracen leaders on 28 March, and was then sent ahead with a small picked force to capture enemy strongholds. His subsequent fate is unknown, and he may have died in the expedition, or perhaps dismissed by the emperor.
