Legio VI Herculia

The VI Herculia had her permanent camp in Teutoburgium (near modern Vukovar) and an advanced castellum in Onagrinum.

They also protected the imperial residence of Diocletian in Sirmium which was also the provincial capital of the province and the Praetorian prefecture of Illyricum.

The Notitia Dignitatum locates the legion still in Illyricum at the beginning of the 5th century.

[1] It is possible that some men from this legion and from the V Iovia formed the Herculians and Jovians, the new imperial bodyguard of Diocletian.

If this identification is correct, VI Herculia men had the appellative Martiobarbuli, since they were expert in throwing small darts, martiobarbuli, carried by five in the inside of their shields.
