This book is excellent, presenting well both the language of heraldry and a compact history of the United Kingdom that accompanies it. It is a rather short book but, I think, accomplishes more than longer and more complicated books on the same subject.
It's a very gentle teaser about heraldry, not systematic or structured, at times little more than a sampler of some coats of arms but I still learned a little. Maybe it's just marketing for the college of arms who still sell them (for close to 10k!).
There are in existence a great many guides and textbooks of heraldry, most of which inevitably repeat much the same information in much the same way. Heraldry is, after all, a conservative topic. Friar is an established heraldic authority as well as a Fellow of the Royal Society of Arts, while Ferguson is a highly regarded heraldic artist and illustrator, which makes this volume one of the best available on the visual depiction of coat armor in all its aspects, from the standards of the Romans to the assumed arms of Dwight Eisenhower. The history of English arms proceeds from the golden dragon of the West Saxons through the leopards (or lions) of the Angevins (as illustrated by a surviving seal of Eleanor of Aquitaine), and on to the Commonwealth (which nevertheless included royal symbols). Many seals of noble families are reproduced, including the Warennes, Mortimers, Montacutes, Bohuns, Hollands, Talbots, Staffords, and many others. The evolution of the royal arms is followed in great detail, as it encapsulates so much of the history of the nation. The authors also provide an excellent exposition on the development of the multilayered Union Flag, on trends in contemporary grants of arms (including those to American citizens), and on civic and corporate heraldry, as well as giving limited attention to heraldry on the Continent. Friar also has some pointed comments to make regarding overly ostentatious augmentation and the decline in heraldic taste. The latter part of the volume explains the parts of the complete achievement, the nature of ordinaries, subordinaries, and charges, and the use of colors, metals, and furs. Ferguson’s illustrations throughout, both pen-and-ink and airbrushed color, are excellent and clear. This is by no means the only book to which the student should refer but it’s an excellent one with which to start.
