[Illustration: _Men-at-Arms, Fourteenth Century._] Next, round plates of metal, called _placates_ or _roundels_, were applied to shield the armpits from a thrust; and sometimes they were used also at the elbow to protect the inner side of the joint where, for the convenience of motion, it was destitute of armour. An example of a roundel at the shoulder will be seen in one of the men-at-arms in the woodcut on p. 339. Another curious fashion which very generally prevailed at this time--that is, at the close of the thirteenth and beginning of the fourteenth century--was the _ailette_. It was a thin, oblong plate of metal, which was attached behind the shoulder. It would to some extent deaden the force of a blow directed at the neck, but it would afford so inartificial and ineffective a defence, that it is difficult to believe it was intended for anything more than an ornament. It is worn by the foremost knight in the cut on p. 335. Perhaps the next great improvement was to protect the foot by a shoe made of plates of iron overlapping, like the shell of a lobster, the sole being still of leather. Then plates of iron, made to fit the limb, were applied to the shin and the upper part of the forearm, and sometimes a small plate is applied to the upper part of the arm in the place most exposed to a blow. Then the shin and forearm defences were enlarged so as to enclose the limb completely, opening at the side with a hinge, and closing with straps or rivets. Then the thigh and the upper arm were similarly enclosed in plate. It is a little difficult to trace exactly the changes which took place in the body defences, because all through this period it was the fashion to wear a surcoat of some kind, which usually conceals all that was worn beneath it. It is however probable that at an early period of the introduction of plate a breastplate was introduced, which was worn over the hauberk, and perhaps fastened to it. Then, it would seem, a back plate was added also, worn over the hauberk. Next, the breast and back plate were made to enclose the whole of the upper part of the body, while only a skirt of mail remained; _i.e._ a garment of the same shape as the hauberk was worn, unprotected with mail, where the breast and back plate would come upon it, but still having its skirt covered with rings. In an illumination in the MS., is a picture of a knight putting off his jupon, in which the "pair of plates," as Chaucer calls them in a quotation hereafter given, is seen, tinted blue (steel colour), with a skirt of mail. At this time the helmet had a fringe of mail, called the _camail_, attached to its lower margin, which fell over the body armour, and defended the neck. It is clearly seen in the hindermost knight of the group in the woodcut on p. 339, and in the effigy of John of Eltham, on p. 342.
