Neil Gaiman is one of the most widely known writers of the twentieth and twenty-first centuries, having produced fiction and nonfiction, fantasy and horror, television, comics, and prose. He often attributes this eclecticism to his "compost heap" approach to writing, gathering inspiration from life, religion, literature, and mythology.

Readers love to sink into Gaiman's medieval worlds-but what makes them "medieval"? Shiloh Carroll offers an introduction to the idea of medievalism, how the literature and culture of the Middle Ages have been reinterpreted and repurposed over the centuries, and how the layers of interpretation have impacted Gaiman's own use of medieval material. She examines influences from Norse mythology and Beowulf to medieval romances and fairy tales in order to expand readers' understanding and appreciation of Gaiman's work, as well as the rest of the medievalist films, TV shows, and books that are so popular today.
