Legio VI Herculia

This legion was created by the emperor Diocletian (284-305). It was called after his colleague, the emperor Maximianus, who often called himself Herculius, 'the one like Hercules'. The date of the creation of this legion is not known, but was probably at the beginning of the joint reign of the two emperors.

Together with V Iovia, which seems to have been the twin of VI Herculia, it was stationed in the newly created province of Pannonia Secunda, where it protected, from its base at Teutoburgium (near modern Vukovar), the important city Sirmium (Srem Mitrovica). Several rooftiles attest to its presence.
