During the clash between Emperor Gallienus and the Emperor of the Gallic Empire Postumus, XI Claudia fought for the first, receiving the titles Pia V Fidelis V and Pia VI Fidelis VI ('Five/Six times faithful and loyal').
Description
Legio XI Claudia Pia Fidelis (faithful and loyal Claudian legion) dates back to the two legions (the other was the XIIth) recruited by Julius Caesar to invade Gallia in 58 BC, and it existed at least until early 5th century, guarding lower Danube in Durostorum (modern Silistra, Bulgaria). The emblem of this legion is not recorded; it could have been, as were all Caesar's legions, the bull, possibly the she-wolf feeding the twins.
