Not only does any tale which crosshatches between this world and Faerie owe a Founder's Debt to Lord Dunsany, but the secondary world created by J.R.R. Tolkien--from which almost all fantasylands have devolved--also took shape and flower from Dunsany's example. --The Encyclopedia of Fantasy. Most fantasy enthusiasts consider Lord Dunsany one of the most significant forces in modern fantasy; his influences have been observed in the works of H.P. Lovecraft, L. Sprague de Camp, Fritz Leiber, Jack Vance, and many other modern writers. The Book of Wonder is Dunsany at his peak of his talent. The stories here are a lush tapestry of language, conjuring images of people, places, and things which cannot possibly exist, yet somehow ring true. They are, in short, full of wonder. Together with Dunsany's other major collections, A Dreamer's Tales and Tales of Three Hemispheres, they are a necessary part of any fantasy collection.
Edward John Moreton Drax Plunkett, Baron of Dunsany (1878 – 1957) was an Irish writer and dramatist, notable for his work, mostly in fantasy, published under the name Lord Dunsany. More than eighty books of his work were published, and his oeuvre includes many hundreds of published short stories, as well as successful plays, novels and essays. Lord Dunsany is the author of such celebrated works as The Book of Wonder (1912) and The King of Elfland's Daughter (1924). Over the course of a career that spanned more than five decades, Dunsany wrote thousands of stories, plays, novels, essays, poems, and reviews, and his work was translated into more than a dozen languages. Today, Dunsany's work is experiencing a renaissance, as many of his earlier works have been reprinted and much attention has been paid to his place in the history of fantasy and supernatural literature.
