In later days, when tournament crests were made of leather, the weight even of these was very considerable, but for tournament purposes that weight could be endured. Half-a-dozen courses down the _barrière_ would be a vastly different matter to a whole day under arms in actual battle. Now a crest cut out from a thin plate of metal set {332} on edge would weigh but little. But perhaps the strongest proof of all is to be found in the construction of so many German crests, which are adorned down the back with a fan. Now it is hardly likely, if the demi-lion in relief had been the earliest form, that the fan would have been subsequently added to it. The fan is nothing more than the remains of the original fan-shaped ornament left when the crest, or most likely only the front outline of it, had been cut out in profile from the fan. We have no instance until a very much later period of a crest which could not be depicted in profile, and in the representations of crests upon seals we have no means of forming a certain judgment that these representations are not of profile crests, for the very nature of the craft of seal-engraving would lead the engraver to add a certain amount of relief, even if this did not actually exist. It is out of the question to suppose, by reason of their weight, that crests were made in metal. But if made of leather, as were the tournament crests, what protection did the crest add to the helmet? The fact that wreaths and coronets did not come into use at the earliest advent of crests is confirmatory evidence of the fact that modelled crests did not exist, inasmuch as the fan prolonged in front and prolonged behind was narrowed at its point of contact with the helmet into such a diminished length that it was comparatively easy to slip the mantling by means of a slit over the fan, or even drape it round it.
