Legio XIV Gemina ("The Twinned Fourteenth Legion") was a legion of the Imperial Roman army, levied by Julius Caesar in 57 BC.^[1] The cognomen Gemina (Twinned) was added when the legion was combined with another understrength legion after the Battle of Actium. The cognomen Martia Victrix (martial and victorious) was added following their service in the Pannonian War c. AD 9 and the defeat of Boudicca in AD 61. The emblem of the legion was the Capricorn, as with many of the legions levied by Caesar.^[2]
