1911 Encyclopædia Britannica/Caractacus

CARACTACUS, strictly Caratācus, the Latin form of a Celtic name, which survives in Caradoc and other proper names. The most famous bearer of the name was the British chieftain who led the native resistance to the Roman invaders in A.D. 48–51, and was finally captured and sent to Rome (Tac. Ann. xii. 33, Dio. lx.). Two old camps on the Welsh border are now called Caer Caradoc, but the names seem to be the invention of antiquaries and not genuinely ancient memorials of the Celtic hero.
