A round shield is a circular defensive tool used primarily in combat. Historically, it has been made from various materials, including wood, metal, and leather. Round shields were popular among ancient warriors, such as the Vikings and Roman soldiers, due to their effectiveness in blocking attacks and their ease of maneuverability. These shields often featured decorative designs or symbols, representing the warrior's clan or personal identity. The round shape allowed for better coverage and protection, making it a favored choice in battles. Today, round shields are often seen in historical reenactments and are studied for their significance in ancient warfare.
