NOMENCLATURE.--Like its language, the Nomenclature of English Heraldry is of a mixed character, in part technical and peculiar to itself, and in part the same that is in common use. Thus, many of the figures and devices of Heraldry have their peculiar heraldic names and titles, while still more bear their ordinary designations. Descriptive terms, whether expressed in English or in French (Anglo-Norman), are generally employed with a special heraldic intention and significance. In the earliest Roll of Arms known to be now in existence, which was compiled (as appears from internal evidence) between the years 1240 and 1245, the Nomenclature is the same that is found in Rolls and other heraldic documents of a later date. This fact of the existence of a definite Nomenclature at that time, proves that before the middle of the thirteenth century the Heraldry of England was subject to a systematic course of treatment, and had become established and recognised as a distinct and independent Science. STYLE AND FORMS OF EXPRESSION.--With the Nomenclature, a settled Style and certain fixed technical Forms of Expression were introduced and accepted in the thirteenth century; and, since that period, the Style and Forms of Expression have undergone only such comparatively slight modifications as tended to render them both more complete and more consistent. As it was at the first, it still is the essence of heraldic language to be concise yet complete, expressive, and also abounding in suggestions. Not a syllable is expressed that is not absolutely necessary; not a syllable omitted, the absence of which might possibly lead to any doubt or uncertainty. In the more matured style, the repetition of any important word in the same sentence is scrupulously avoided; and, where it would be required, another form of expression is substituted in its stead. Much meaning also is left to be implied and understood, through inference, either based upon certain accepted rules and established heraldic usages for the arrangement of the words and clauses of a sentence, or derived from the natural qualities and characteristic conditions of certain figures and devices: but, nothing is ever left to be inferred when an uncertain inference might possibly be adopted, or that can be understood clearly and with certainty only by means of an explicit statement. Superfluous words and particles of all kinds are altogether omitted. Descriptive epithets follow the nouns to which they refer: as, a _red cross_ is styled a _cross gules_. The general rules, by which the arrangement of the words in heraldic descriptive sentences is determined, will be found in the last subdivision of this chapter. Examples of heraldic Language, Nomenclature, Style and Forms of Expression, will be given in abundance throughout the following chapters and sections of this treatise. With these examples students will do well to familiarise themselves: then,
