By what rules the colours of the mantlings were decided in early times it is impossible to say. No rules have been handed down to us--the old heraldic books are silent on the point--and it seems equally hopeless to attempt to deduce any from ancient armorial examples. The one fact that can be stated with certainty is that the rules of early days, if there were any, are not the rules presently observed. Some hold that the colours of the mantling were decided by the colours of the actual livery in use as distinct from the "livery colours" of the arms. It is difficult to check this rule, because our knowledge of the liveries in use in early days is so meagre and limited; but in the few instances of which we now have knowledge we look in vain for a repetition of the colours worn by the retainers as liveries in the mantlings used. The fact that the livery colours are represented in the background of some of the early Garter plates, and that in such instances in no single case do they agree with the colours of the mantling, must certainly dissipate once and for all any such supposition as far as it relates to that period. A careful study and analysis of early heraldic emblazonment, however, reveals one point as a dominating characteristic. That is, that where the crest, by its nature, lent itself to a continuation into the mantling it generally was so continued. This practice, which was almost universal upon the Continent, and is particularly to be met with {386} in German heraldry, though seldom adopted in England, certainly had some weight in English heraldry. In the recently published reproductions of the Plantagenet Garter plates eighty-seven armorial achievements are included. Of these, in ten instances the mantlings are plainly continuations of the crests, being "feathered" or in unison. Fifteen of the mantlings have both the outside and the inside of the principal colour and of the principal metal of the arms they accompany, though in a few cases, contrary to the present practice, the metal is outside, the lining being of the colour. Nineteen more of the mantlings are of the principal colour of the arms, the majority (eighteen) of these being lined with ermine. No less than forty-nine are of some colour lined with ermine, but thirty-four of these are of gules lined ermine, and in the large majority of cases in these thirty-four instances neither the gules nor the ermine are in conformity with the principal colour and metal (what we now term the "livery colours") of the arms. In some cases the colours of the mantling agree with the colours of the crest, a rule which will usually be found to hold good in German heraldry. The constant occurrence of gules and ermine incline one much to believe that the colours of the mantling were not decided by haphazard fancy, but that there was some law--possibly in some way connected with the sumptuary laws of the period--which governed the matter, or, at any rate, which greatly
