The barred or grilled helmet owed its introduction to tournaments with swords and clubs, which necessitated better opportunities of vision than the earlier tilting-helm afforded, sufficient though that was for encounters with the tilting-spear. The earliest form of this type of helmet will be seen in Fig. 606, which is termed a "grid-iron" helmet, developing shortly afterwards into the form of Fig. 607, which has a lattice-work visor. The former figure, the "grid-iron" helmet, is a {316} representation taken from an original now in the possession of Count Hans Wilczek, of Vienna. Fig. 607, the helmet with the latticed visor, is from an example in the German National Museum at Nürnberg. Neither of these types of helmet appears to have been regularly adopted into heraldic art. Indeed they are seldom, if ever, to be found in heraldic emblazonment. For pictorial and artistic purposes they seem to be entirely supplanted in paintings, in seals, and in sculpture by the "grilled" helmet or "buckler." Whether this helmet, as we find it depicted in paintings or on seals, was ever really worn in battle or tournament seems very doubtful, and no actual instance appears to have been preserved. On the other hand, the so-called "Prankhelme" (pageant helmet) bucklers, frequently made of gilded leather and other materials, are extant in some number. It is evident from their nature, however, that they can only have been used for ceremonial or decorative purposes. Fig. 608 shows one of these buckled "pageant" helmets surmounted by the crest of the Margraviate of Burgau. Fig. 609 shows another of these pageant helmets, with the crest of Austria (ancient) or of Tyrol. These were borne, with many others of the same character, in the pageant of the funeral procession of the Emperor Frederick III. (IV.) in 1493. The helmets were made of leather, and gilded, the two crests being carved out of boards and painted. The Burgau wings, which are inclined very far forward, are: "Bendy of six argent and gules, charged with a pale or." In their normal position the wings are borne upright. The second crest, which is 86 cm. in height, is black, and adorned on the outside with eared pegs 4 cm. long, from which gold linden-leaves hang. These helmets and crests, which were formerly in St. Stephen's Cathedral, are now in the Vienna Historical Museum. At the beginning of the seventeenth century the workmanship became inferior, and beauty of line was no longer sought after. Shortly afterwards helmets ceased to be worn outside the regular army, and with the subsequent evolution of military head coverings heraldry has no concern. As a part of a heraldic achievement the helmet is not so old as the shield. It was not until the introduction of the crest that any one thought of depicting a helmet with a shield.
