Res, artes et religio is a collection of thirty-nine essays in honour of Rudolf Simek, professor at the Department of German, Comparative Literature and Culture at the University of Bonn. The terms res, artes and religio describe the wide-ranging interests of Rudolf Simek, which centre around but are by no means limited to the area of Viking Age and medieval Scandinavia. The chapters gathered here, written by his friends, colleagues and students, match these interests and show the influence of his work in the fields of mythology, religious studies, runology, saga studies, archaeology and more.
