An epic concept art of a Roman centurion's helmet, positioned alone with no person underneath. The helmet is highly detailed, with intricate engravings of Roman symbols, mythological creatures, and the letters 'S.P.Q.R.' subtly engraved near the brow. The metal is polished yet shows subtle battle wear, with a slightly tarnished gold and steel sheen. The red plume is bold and dramatic, with finely rendered individual bristles that curve gracefully. The background is dark and atmospheric, with soft, ambient golden light highlighting the helmet, creating a sense of reverence and history. Ancient Roman ruins are faintly visible in the misty background, enhancing the legendary and majestic aura of this iconic piece of armor. The focus remains solely on the helmet, capturing its strength and artistry
