The question as to when coats of arms were first introduced is very uncertain, but it is thought that the custom had its origin in the first crusade, when distinguishing marks among such a motley crowd of warriors were more especially needful. During this crusade the several nationalities taking part in it were distinguished by different coloured crosses sewn on to their garments, each leader displaying his own colour and device; but heraldic bearings first became generally hereditary in the reign of Henry III. His seal shows the king with the fingers of his chain-mail gloves articulated, and wearing the great helm. An early example of a helm with a heraldic device occurs on an effigy of Johan le Botiler about 1300. It is figured in Hewitt. The shield on the brass of Sir John Daubernoun bears a distinctly heraldic device. Heraldry seems to have been most studied, prized, and practised during the fourteenth century. An illumination in the Loutterell Psalter, dating from the middle of the same century, shows heraldic devices spread over the entire person of a knight; being emblazoned over the body, ailette, banner, pennon, saddle, shield, and on the housings of the steed, as well as on the dresses of the ladies of the knight’s family. The numerous tournaments of this period encouraged its use and development, mainly in the sense of ostentation and pride of birth. In the Tower collection is a figure on horseback clad entirely in chain-mail. To the hood is attached a fillet of iron round the head. The hauberk has long arms terminating in gloves of mail. A leathern belt with strong iron clasps encircles the waist. Excepting the legs the horse is fully barded with leathern armour, fortified with iron scales. The armour on the figure is labelled “Indian,” and the horse “Persian.” There are two hauberks at Carlsruhe of riveted chain-mail, hood and tunic in one piece, but the head bears no fillet. On the breast, over nipples and navel, are three small palettes inscribed with Oriental characters; and inscribed clasps at the waist fasten the tunic. These suits are chiefly remarkable for the presence of the hood, and the date of the mail is about fourteenth century. There are two shirts of mail at Brancepeth Castle, Durham, which are riveted, and probably of early fourteenth century date. It was not uncommon for hauberks to be provided with reinforcements of leathern thongs, which were intertwined through the rings; there is an example of this kind in the Rotunda at Woolwich. This description of reinforced chain-mail is referred to later under the paragraph dealing with “banded” mail. An effigy of a knight in the Temple Church, that of Geoffrey de Mandeville, Earl of Essex (1144), in the reign of King Stephen, engraved by Stothard, shows the warrior armed completely in chain-mail, having a hood of mail over the head and shoulders, surmounted by a cylindrical helmet without nasal. The hauberk is in
