Book excerpt: Anthony Wood is one of the country's foremost professional calligraphers, illuminators and heraldic artists and he has applied his vast experience to the compilation of this very comprehensive but readable book. A former college lecturer specialising in these subjects, he takes the reader through all aspects of heraldic art, explaining the terminology and historical background as well as describing the various techniques and the use of materials. Design is a vital element of heraldic art and much advice is given on acceptable and appropriate components of achievements of arms. The book is illustrated throughout with many black and white and full colour examples of the author's work.
