Legio I Iovia

This legion was created by the emperor Diocletian (284-305), who was often called Iovianus, 'the man like Jupiter'. The date is unknown, but was probably at the beginning of his reign. Together with II Herculia, which seems to have been the twin of I Iovia, it was stationed in the newly created province of Scythia (near the mouth of the Danube). It was still there when the text known as the Notitia Dignitatum (a list of magistracies and army units) was composed (c.400), and may survived into the early Byzantine Empire.
