One of the best aspects of the science fiction genre is the way it has the ability to play around with ideas of time and space. Rather than being confined to the existing ideas of linear time, singular dimensions, or fixed settings, science fiction authors can have their characters travel forward and backward in time, meet extraterrestrial beings from a completely different timeline, or send the book’s cast to an entirely different planet. These aspects mean that, while science fiction is often thought of as a futuristic genre, there is plenty of opportunity to incorporate aspects of the past or even set whole books there.

In the books below, the authors play around with time in a way that combines medieval aspects with futuristic technologies and alien species. This might involve a group of advanced interstellar beings landing in the middle of an English battlefield, or it might mean a legend from the Middle Ages regenerates in a futuristic time. Other books may have less explicit connections to the medieval world but still draw on its complex social and imperial history or its courtly structures to inspire their plots. Whichever it may be, all of these medieval science fiction titles provide ways to think about how science fiction gives readers the chance to play with the limits of time, space, and history that we know today. Read on to find out more about how science fiction authors incorporate medieval themes and aspects into their work.

Noor by Nnedi Okorafor book cover

Noor by Nnedi Okorafor

Okorafor has spoken before about how the concept of global medievalism informs much of her work in terms of inspiring plotlines and characters. If you’re interested in how she combines those ideas with themes of Africanfuturism, check out her science fiction novel Noor, which is set in a futuristic Nigeria. There, a young woman named Anwuli Okwudili is on the run for her life. Anwuli, or AO, as she thinks of herself, was labeled “wrong” before she was ever born and was further injured in a car accident, which means she has several body augmentations. This has come at the cost of Anwuli’s acceptance in society and has made her an object of scorn and fear. The novel explores the ties between bodies, technology, and community.

A Canticle for Leibowitz by Walter C. Miller Jr. book cover

A Canticle for Leibowitz by Walter M. Miller, Jr.

The monastic setting of this story conjures up images of medieval monks, even as the story is set in a distant and apocalyptic future. Miller reimagines the idea of a Dark Age amongst the survivors of an atomic Flame Deluge. Humanity has turned against science, and only the Order of St. Leibowitz, alone in a desert monastery, maintains a connection to the knowledge of the past. A science fiction classic.
