"A Complete Guide to Heraldry" by Arthur Charles Fox-Davies is a comprehensive reference work on the science of heraldry written in the early 20th century. This publication delves into the history, laws, and practices associated with coats of arms, including their origins, symbolism, and the functions of heralds. The guide is not merely historical but emphasizes the continuing relevance and application of heraldry in the modern era. The opening of the book establishes an overview of armory and its distinctions from heraldry, explaining that armory concerns the symbolic imagery on heraldic devices while heraldry encompasses broader ceremonial and genealogical facets. Fox-Davies critiques the misconceptions surrounding armory, arguing that it is not a stagnant field confined to the past but a living discipline adapting to contemporary contexts. He asserts that while ancient practices influence it, the rules governing armory must evolve with societal changes, setting the stage for a thorough exploration of heraldic principles and their modern implications.
