Round Shield
Viking circular wooden shield
The round shield is the branch of shield made of a flat disk of one round face, and its clearest form is the round shield carried by the Viking warrior of Scandinavia in the 8th to 11th centuries. It was made of light wooden planks (mostly linden or fir), some seventy-five to ninety centimeters across, joined together with the grain alternating, with an iron boss at the center to cover the man's fist, and within the boss a short handle held in one hand. Weighing three to five kilograms, it was light enough to be swung freely in one hand, compared to the great kite shields and round targes of the same age, and the boss itself was used as a weapon, struck straight at the face or sword-hand of the enemy. In the shield wall (skjaldborg), in which the warriors stood in a single line and overlapped their shields slightly, the same shield held its greatest seat, while a warrior bearing one alone, with sword and axe each in a hand, flowed back and forth and fought.
