A Legio VI fought in the Roman Republican civil wars of the 40s and 30s BC. Sent to garrison the province of Judaea, it remained there for the next two centuries.
The Legion was also known as Fidelis Constans, meaning “loyal and steadfast”. It is unclear when this title was given, but several sources indicate that it may have been in the 1st century AD. The symbol for Legio VI Ferrata was the bull. It also carried the symbolic she-wolf with Romulus and Remus.
