Legio II Herculia
Legio II "Herculia" ("devoted to Hercules") was a Roman legion, levied by Emperor Diocletian (284–305), possibly together with I "Iovia", to guard the newly created province of Scythia Minor. It was stationed at Capidava. The "cognomen" of this legion came from "Herculius", the attribute of Maximian (Diocletian's colleague) meaning "similar to Hercules". According to "Notitia Dignitatum", at the beginning of the 5th-century, II "Herculia" was still in its camp on the Danube.
