The Bayeux tapestry--worked, there is little doubt, in the middle of the eleventh century, but whether embroidered in England by order of Matilda for an English cathedral, or in Normandy by noble ladies or hirelings--is of comparatively little moment so long as its authenticity as an approximately contemporaneous monument of the reign of the Conqueror is generally admitted, and this is happily the case. It shows that the Conqueror’s chivalry wore conical helms with the nose-guard and hood of mail for protecting the neck, shoulders, and part of the face. The hauberks reached down over the thighs, with a slit in the middle of the skirt for convenience on horseback; and the mail on the arms usually came nearly to the elbows, but sometimes to the wrists; and the continuous coif occurs frequently. The hauberk of this period had no division down the front, but was drawn on over the warrior’s head. The Norman knights bear pear-shaped, convex shields with a point at the bottom, secured to the arm by a leathern strap, and large enough to cover the body from the shoulders to the hips; some with a rough device. Some of the shields shown are polygonally formed, with a central spike. The Saxon shields on the tapestry are round or oval, with a central umbo. Maces are shown in the hands of some of the figures. With the exception of William himself, whose legs are encased in chausses, probably of leather, with reinforcing scales or rings, the limbs of his knights are simply swathed in thongs. Probably only the richer knights wore chain-mail, the majority having hauberks of cuir-bouilli (boiled leather) strengthened by continuous rings sewn on to it, side by side or overlapping. Some also had the pieces of lozenge-shaped metal already mentioned, called jazerine or jazerant; or scales, which were occasionally of horn, fixed on to the leather. It is impossible to determine these details absolutely, as all the armour looks very much alike on the tapestry in its present condition, this being especially the case where rings were used; and it is only by careful comparison with other contemporary evidence that any reasonable certainty can be assured. This has naturally given rise to a great diversity of interpretation; and the same difficulty arises with seals. The knights wore no surcoats over their mail. The great seal of William the Conqueror shows him in a hauberk coming down to the knees, with short sleeves and no leg armour. Under the hauberk was the gambeson and tunic. The helm is hemispherical, and fastened under the chin. The Germans were probably before us in the general use of real chain-mail, for the epic poem of Gudrun, written in the tenth century, states how Herwig’s clothes “were stained with the rust of his hauberk.”
