This volume assembles 13 essays as the result of a workshop for international doctoral and post-doctoral researchers in Old Norse studies, which was held at the Institute for Nordic Philology at LMU in Munich in December 2015. The contributions focus lies on different aspects of bad or evil characters in saga literature, and they give testimony to the broad literary variety such figures display in Old Norse texts. The Antagonists and Troublemakers in Old Norse Literature are here explored in their diversity, ranging from their literary psychology to their characteristics which often challenge gender norms. The contributions discuss the narrative strategies of presenting these characters to the audience, both positively and negatively. Furthermore, they analyse how the central paradox of evil and its dependence on context is realised in various ways in Old Norse literature.
