The smaller viking shield sizes come from the pagan period for the Saxons and the larger sizes from the 10th and 11th centuries. By the beginning of the eleventh century the bottom edge of the viking shield evolved downwards to cover the upper leg giving rise the kite shield. There is evidence for both flat and curved kite shields, with the curved being most likely, and most having bosses. It is debatable whether or not these bosses were used in the same fashion as round shields; i.e. centre gripped. The tendency in re-enactment is to wear them crossbraced, as if you were still riding. This is because if the shield is held near the boss, the lower section acts like a pendulum making it difficult to operate. Most viking shields are shown in illuminations as being painted a single colour although some have a design painted onto them; the commonest designs are simple crosses or derivations of sun wheels or segments. The few round shields that survived have much more complicated designs painted on them and sometimes very ornate silver and gold work applied around the boss and the strap anchors.
