The figure of Goliath, which we gave in our last chapter (p. 322), will serve very well for a general representation of a knight of the twelfth century. In truth, from the Norman Conquest down to the introduction of plate armour at the close of the thirteenth century, there was wonderfully little alteration in the knightly armour and costume. It would seem that the body armour consisted of garments of the ordinary fashion, either quilted in their substance to deaden the force of a blow, or covered with _mailles_ (rings) on the exterior, to resist the edge of sword or point of lance. The ingenuity of the armourer showed itself in various ways of quilting, and various methods of applying the external defence of metal. Of the quilted armours we know very little. In the illuminations is often seen armour covered over with lines arranged in a lozenge pattern, which perhaps represents garments stuffed and sewn in this commonest of all patterns of quilting; but it has been suggested that it may represent lozenged-shaped scales, of horn or metal, fastened upon the face of the garments. In the wood-cut here given from the MS. Caligula A. vii., we have one of the clearest and best extant illustrations of this quilted armour. In the mail armour there seem to have been different ways of applying the _mailles_. Sometimes it is represented as if the rings were sewn by one edge only, and at such a distance that each overlapped the other in the same row, but the rows do not overlap one another. Sometimes they look as if each row of rings had been sewn upon a strip of linen or leather and then the strips applied to the garment. Sometimes the rings were interlinked, as in a common steel purse, so that the garment was entirely of steel rings. Very frequently we find a surcoat or chausses represented, as if rings or little discs of metal were sewn flat all over the garment. It is possible that this is only an artistic way of indicating that the garment was covered with rings, after one of the methods above described; but it is also possible that a light armour was composed of rings thus sparely sewn upon a linen or leather garment. It is possible also that little round plates of metal or horn were used in this way for defence, for we have next to mention that _scale_ armour is sometimes, though rarely, found; it consisted of small scales, usually rectangular, and probably usually of horn, though sometimes of metal, attached to a linen or leather garment. [Illustration: _Quilted Armour._] The shield and helmet varied somewhat in shape at various times. The shield in the Bayeux tapestry was kite-shaped, concave, and tolerably large, like that of Goliath on p. 322. The tendency of its fashion was continually to grow shorter in proportion to its width, and flatter. The round Saxon target continued in use throughout the Middle Ages, more especially for foot-soldiers.
