Over the years, the field guide and the coffee table book have merged, and we now have coffee table-ish books (but serious books) that include a species description of every critter in a certain clade. In the case of Horses of the World by Élise Rousseau (Author), Yann Le Bris (Illustrator), Teresa Lavender Fagan (Translator), while every living species of horse is in fact covered, the book is a comprehensive guide to breeds of horses.

Of which there are 570.

A horse is horse, of course, but but is a donkey or an ass? What about zebras?

Horse people are very picky about what they call a horse. It is generally thought that there are onlly three living or recent species of horse. The Prewalski’s horse (Equus ferus prezewalski), which lives in Asia, the tarpan (Equus ferus ferus) which is the European version of this animal, and went extinct when the last zoo inmate of this species died in 1909, and the modern horse, Equus ferus caballus. But if you think of a horse as a member of the genus Equus, there are more, including the donkey/ass and three species of zebra, the Kiang (a Tibetan ass), and another Asian ass called the Onager. And, since when speaking of horses, the extinct European wild horse is generally mentioned, we will add the Quagga, the half horse-half zebra (in appearance) African equid that went extinct in 1984 (having disappeared from the wild in 1883).

Since “horses” (as in Mr. Ed and friends) and Zebras can interbreed successfully, and some of these other forms can as well to varying degrees, we need to think of Equus as a close knit genus and not be exclusionary in disregarding the Zebra and Donkey.

Anyway, that is not what this book is about. As noted, there are some 570 or possibly more varieties of horse (no two experts will likely agree on that number) and Horses of the World covers them all. There is introductory material about horses, breeds, how we tell them apart, conservation status, etc. Each horse breed is then given one half of a page on each of two folios, so you see overleaf some illustrated text on one side, and a fuller and very official illustration on the other, for most breeds, with some variation.

This is one of the few books that comes with a movie, compete with some rather galloping music:

Élise Rousseau is the author of numerous books on horses. Illustrator Yann Le Bris has illustrated numerous books.
