The Description of a New World, Called The Blazing-World, better known as The Blazing World, is a 1666 work of prose fiction by the English writer Margaret Cavendish, the Duchess of Newcastle. Feminist critic Dale Spender calls it a forerunner of science fiction. It can also be read in the context of utopias.
As its full title suggests, Blazing World is a fanciful depiction of a satirical, utopian kingdom in another world (with different stars in the sky) that can be reached via the North Pole. It is "the only known work of utopian fiction by a woman in the 17th century, as well as one of the earliest examples of what we now call 'science fiction' — although it is also a romance, an adventure story, and even autobiography."
A young woman enters this other world, becomes the empress of a society composed of various species of talking animals, and organizes an invasion back into her world complete with submarines towed by the "fish men" and the dropping of "fire stones" by the "bird men" to confound the enemies of her homeland, the Kingdom of Esfi.
The work was initially published as a companion piece to Cavendish's Observations upon Experimental Philosophy and thus functioned as an imaginative component to what was otherwise a reasoned endeavour in 17th century science. It was reprinted in 1668.
Cavendish's book inspired a notable sonnet by her husband, William Cavendish, 1st Duke of Newcastle-upon-Tyne, which celebrates her imaginative powers. The sonnet was included in her book.
In Alan Moore's graphic novels chronicling the adventures of The League of Extraordinary Gentlemen, the Blazing World was identified as the self-same idyllic realm from which the extra-dimensional traveller Christian, a member of the first League led by Duke Prospero, had come in the late 1680s. The league disbanded when Christian returned to this realm, and it was to where Prospero, Caliban and Ariel also departed many years later.
