A buckler (French bouclier 'shield', from Old French bocle, boucle 'boss') is a small shield, up to 45 cm (up to 18 in) in diameter, gripped in the fist with a central handle behind the boss. It became more common as a companion weapon in hand-to-hand combat during the Medieval and Renaissance periods. Its size made it poor protection against missile weapons (e.g., arrows) but useful in deflecting the blow of an opponent's weapons, binding their arms, hindering their movements, or punching them. The seminal study of the topic has been undertaken by Herbert Schmidt and has devised the following typology: with the cross-section of the buckler further refining these types: The combination of the two classifiers determines the buckler type. Thus a Type Ia buckler is a round flat buckler; a Type IId buckler is a square wavy buckler, which would be typical of an Italian targa MS I.33, considered the earliest extant armed-combat manual, (around 1300) contains an early description of a system of combat with buckler and sword.

Uses

The buckler was widely used, a simple yet effective weapon, often combined with an arming sword, falchion, or rapier. It was popular circa 1100 to 1600. The buckler had a variety of roles when it came to swordplay, but five principal means come to the fore as described in MS I.33. Each use recognizes the shield's small size and maneuverability when dealing with light blades.

Decoration

In classical antiquity, bucklers on medals were either used to signify public vows rendered to the gods for the safety of a prince, or that he was esteemed the defender and protector of his people: these were called votive bucklers, and were hung at altars, etc.
