Much of what gives the books their particular flavour is their far future setting. In the tradition of Jack Vance’s Dying Earth novels and M. John Harrison’s Viriconium stories, The Book Of The New Sun’s medieval-tinged Fantasy world of swords, guilds, apprentices and nobles reveals itself to be set thousands of years in the future, in a time when the Earth, now called the Urth, is so old the sun is dying and much of the technological and scientific advances of our time and the future have been lost or forgotten. Wolfe creates this atmosphere through his use of obscure archaic words to describe the coins, the military and social ranks, and the animals. The unfamiliar yet evocative words create a sense of strangeness and mystery, and they also tell the reader what, say, the animals are similar to and what they are used for whilst subtly reminding them that these are animals bred from extraterrestrial and Earth animal crosses or genetically altered by future science.
