E.R. Eddison (1882-1945) was an English fantasy writer, known for his complex and highly-stylized prose, particularly his "Zimiamvian" fantasy works:
* The Worm Ouroboros (1922) - his most famous work, a fantastical epic set in a world ruled by dragons and wizards.
* A Fish Dinner in Memison (1933) - a short novella about a strange world and a mysterious dinner.
* Mistress of the Mist (1935) - a collection of short stories in a similar style to "The Worm Ouroboros".
* The Road to Mithras (1924) - a collection of fantasy stories, including the title story which was later expanded into a novel.
* The Adventures of the Elf-Knight (1930) - a collection of stories that predate Eddison's most famous works.
