The third great protection is the shield. These have been getting smaller as hauberks and helmets have been improving; but one cannot trust solely to the body armor. Besides, a shield is a kind of offensive weapon. A sharp thrust with its edge or a push with its broad surface may often knock your opponent over. Aimery's new shield is semioval and slightly pointed at the bottom. It covers its possessor from shoulder to knees while sitting on his horse. The stoutest kind of hide is used in making it, with a backing of light, tough wood, and a strong rim of metal. It curves inward slightly for the better protection of the body. In the center is a metal knob, usually of brilliant brass, and the name "buckler" comes from this strong "boss" (_boucle_). There is a big leather strap by which the shield is ordinarily carried about the neck; but when you go into action you run your left arm through two strong handles. A shield seems a simple object, but almost as much skill goes into compacting the wood, leather, and metal into one strong mass, not easily split or pierced, as into making the hauberk. The front, of course, is highly colored, and, although the heraldic "coat armor" has yet hardly developed, every cavalier will flaunt some design of a lion, eagle, dragon, cross, or floral scroll. As for the handling of the shield, it is nearly as great a science as the handling of the sword; indeed, the trained warrior knows how to make shield and sword, or shield and lance, strike or fend together almost as one weapon. [Illustration: THIRTEENTH-CENTURY SWORDS] Nevertheless, it is the strictly offensive weapons on which the noble warrior sets greatest store, and the weapon _par excellence_ is the sword. Barons often love their swords perhaps more than they love their wives. They treat them almost as if they are persons. They try to keep them through their entire lives. According to the epics, the hero Roland liked to talk to his sword "Durendal," and Ogier to his "Brans." Conon swears one of his fiercest oaths, "by my good sword 'Hautemise,'" and Aimery has named his new sword "Joyeuse," after the great blade of Charlemagne. [Sidenote: Swords and Lances]
