The Roman Mohawks on their helmets were called "plumes" or "crest." These decorative elements were made from feathers or other materials and served both an aesthetic and practical purpose, helping to identify ranks and units in battle. The crests could vary in color and style, reflecting the individuality of the soldier or the legion to which they belonged.
Plumes of molten rock originating deep within the mantle are known as mantle plumes. These plumes are believed to be responsible for hotspots and volcanic activity at the Earth's surface.
The plume was made of dyed horse hair. Hair was the preferred material because it lasted longer. The red was to intimidate the enemies with the color red which meant blood. The color red was also a sign that the men were soldiers of the emperor. But remember, the ordinary soldier did not have a plume on his helmet except if he were marching in a triumph. Plumes or distinguishing crests were only for officers. The centurion needed the wide crest so his men could more easily see him in battle
