That the making of chain-mail must have been laborious in the extreme we may judge from the fact that the wire which formed the links had to be hammered out from the solid bar or ingot. As far as can be gathered, the art of wire-drawing was not practised till the fourteenth century, at which time Rudolph of Nuremberg is credited with its discovery. The roughly-hammered strips were probably twisted spirally round an iron or wood core and then cut off into rings of equal size (Fig. 1). The ends of the rings were flattened and pierced, and, when interlaced, the pierced ends were riveted together or sometimes, as is the case with Oriental mail, welded with heat. Links that are 'jumped', that is with the ends of the ring merely butted together and not joined, generally show either that the mail is an imitation, or that it was used for some ceremonial purpose; for this insecure method of fixing would be useless in the stress and strain of battle or active service. The most usual method of interlinking the rings is for each ring to join four others, as will be seen in the drawing on Plate I, No. 7. No. 8 on the same plate shows the mail as more generally depicted in illuminations. When we consider the inexperience of the scribes and illustrators of the Middle Ages we must admit that this representation of a very intricate fabric is not only very ingenious but follows quite the best modern impressionist doctrines. Portions of chain-mail survive in most armouries and museums, but their provenance is generally unknown, and much that is of Oriental origin is passed off as European. Chain-mail itself comes in the first instance from the East, but when it was introduced into Europe is difficult, if not impossible, to state. It is certainly represented as worn by the Scythians and Parthians on the Trajan Column, and is probably of greater antiquity still. [Illustration: FIG. 1. Probable method of making links for mail.] From the beginning of the thirteenth century, for about sixty or seventy years, we find a curious arrangement of lines intended to represent a form of defensive armour, both in illuminated manuscripts and also on carved monuments (Plate I, 12, 13).
