The Scutum is a shield carried by Roman soldiers.
The Scutum (Latin for "shield") is a rectangular, semi-cylindrical shield about four feet in height and two-and-a-half feet wide.
The Scutum was as important to the Roman legion as the Hoplon was to the Greek phalanx. Its large size and shape allowed soldiers to interlock their shields to form a nearly impenetrable wall. Even in one-on-one combat, the scutum provided its user with excellent all-around protection.
In addition to Roman soldiers, the Scutum was carried by the Murmillo-class of Gladiator.
