In ancient Greece, shields were essential pieces of military equipment used by hoplites (heavily armed foot soldiers) and other warriors. The shape, size, and material of Greek shields varied across time periods and city-states, but they all shared the common purpose of providing protection in battle. The primary types of shields in ancient Greece were the hoplon, aspis, and thyreos, each serving distinct roles in warfare.
The most iconic and widely used shield in ancient Greece was the hoplon, also known as the aspis. This round shield, typically about 3 feet in diameter, was made of wood and covered with a layer of bronze for additional protection. The hoplon featured a central boss (a raised, often circular projection) that was designed to deflect blows and to serve as a grip. The shield’s distinctive feature was its heavy weight, which made it a formidable piece of armor for close combat. The hoplon was designed to be carried on the left arm, allowing the right hand to wield a spear or sword. This shield played a central role in the famous Greek phalanx formation, where soldiers stood side by side, interlocking their shields to create a nearly impenetrable defense.
The aspis, though often used interchangeably with the hoplon, can refer more specifically to the shape and construction of the shield, which had a slightly deeper curve than the hoplon, offering greater protection to the soldier’s body. The aspis was typically large and circular, made of layers of wood for durability, and it was also sometimes reinforced with bronze or iron edging. As the backbone of Greek heavy infantry, it allowed soldiers to form the tight, overlapping shield walls essential to the success of the phalanx formation in battles like those at Marathon and Plataea.
Another important shield in ancient Greece was the thyreos, which was used by light infantry and often associated with the peltasts, who were lightly armed soldiers. Unlike the hoplon, the thyreos was rectangular and had a curved shape. It was generally lighter and smaller, making it more suitable for fast-moving troops who relied on agility rather than heavy armor. The thyreos was made of leather or light wood and was often reinforced with bronze. This shield was designed to be carried with a strap over the shoulder, allowing for greater maneuverability in battle and in skirmishes, where peltasts would fight at a distance and retreat quickly.
