Among the many literary works of all styles and types referring to epilepsy, fantastic literature forms a distinct and interesting subgroup. The article draws attention to two such works belonging to early 20th century German avant-garde where epilepsy is a key feature. Of the authors, Austrian Alfred Kubin (1877-1959) was a renowned artist and illustrator whose only published (and illustrated) novel "The Other Side" (1909) can be understood as the narrative of a complex epileptic experience, perhaps a dreamy state. Of the other author, Hermann Weyl (1893-1960), very little is known. He was a Jewish neuropsychiatrist who emigrated from Nazist Germany to Argentina in 1933. His only published literary work, the novella "The Epileptic" (1927), displays high literary ambitions. The topic epilepsy provided for him the desired access to the fantastic realm, and his professionality enabled him to address with great expertise aspects as diverse as postictal psychosis and social stigmatization. Both works are, thus, valuable contributions to the tradition of epilepsy in fantastic literature. A brief review of the latter includes Edgar Allan Poe, Victor Hugo, Charles Dickens, Gustav Meyrink, Mervin Peake, Russell Hoban, Eraldo Baldini, Haruki Murakami, Adam Fawer, and Christoph Ransmayr.
