Julius Julianus

Julius Julianus (fl. 315–325) was a Roman politician, the grandfather and namesake of the future emperor Julian.

Life

He served Licinius as praetorian prefect from at least spring 315 to September 324, until Constantine I definitively defeated Licinius. However, the fall of Licinius did not mark the end of Julianus' career, as Constantine had praised Julianus' administration of the State^[1] and chose him, in 325, as suffect to replace a consul fallen in disgrace, Valerius Proculus.^[2] He also served as Praefectus Aegypti in 328.

He was the father of Basilina, wife of Constantine's half-brother Julius Constantius and mother of Emperor Julian,^[3] and of the mother of Procopius; he was probably related to Eusebius of Nicomedia. Julianus was the master of the Gothic philosopher slave Mardonius, who was the teacher of both Basilina and Julian.
