New theories point to Marcus Aurelius Mausaeus Carausius as the origin of Arthur. Carausius was a popular hero who rebelled against the emperor Maximian and minted coins based on the contos head. He has been identified with a Belgic tribe who worshipped a "bear god of the northern constellations and its related symbols, including a pagan type grail cup, magical blade weapons, meteorites, magnetic north, and the seasons named Artor."
