We must, however, pause to mention some other kinds of armour which were sometimes used in place of armour of steel. And first we may mention leather. Leather was always more or less used as a cheap kind of defence, from the Saxon leather tunic with the hair left on it, down to the buff jerkin of the time of the Commonwealth, and even to the thick leather gauntlets and jack boots of the present Life Guardsman. But at the time of which we are speaking pieces of armour of the same shape as those we have been describing were sometimes made, for the sake of lightness, of _cuir bouilli_ instead of metal. Cuir bouilli was, as its name implies, leather which was treated with hot water, in such a way as to make it assume a required shape; and often it was also impressed, while soft, with ornamental devices. It is easy to see that in this way armour might be made possessing great comparative lightness, and yet a certain degree of strength, and capable, by stamping, colouring, and gilding, of a high degree of ornamentation. It was a kind of armour very suitable for occasions of mere ceremonial, and it was adopted in actual combat for parts of the body less exposed to injury; for instance, it seems to be especially used for the defence of the lower half of the legs. We shall find presently, in the description of Chaucer's Sire Thopas, the knight adventurous, that "his jambeux were of cuirbouly." In external form and appearance it would be so exactly like metal armour that it may be represented in some of the ornamental effigies and MSS. drawings, where it has the appearance of, and is usually assumed to be, metal armour. Another form of armour, of which we often meet with examples in drawings and effigies, is one in which the piece of armour appears to be studded, at more or less distant regular intervals, with small round plates. There are two suggestions as to the kind of armour intended. One is, that the armour thus represented was a garment of cloth, silk, velvet, or other textile material, lined with plates of metal, which are fastened to the garment with metal rivets, and that the heads of these rivets, gilt and ornamented, were allowed to be seen powdering the coloured face of the garment by way of ornament. Another suggestion is that the garment was merely one of the padded and quilted armours which we shall have next to describe, in which, as an additional precaution, metal studs were introduced, much as an oak door is studded with iron bolts. An example of it will be seen in the armour of the forearms of King Meliadus in the woodcut on p. 350. Chaucer seems to speak of this kind of defence, in his description of Lycurgus at the great tournament in the "Knight's Tale," under the name of coat armour:-- "Instede of cote-armure on his harnais, With nayles yelwe and bryght as any gold, He had a bere's skin cole-blake for old."
