The book describes the pagan origins of Scandinavia, the interaction between the Vikings and other Europeans, and the concept of time in Norse mythology, and gives a dictionary of deities, themes, and concepts. With 200 entries of up to four pages each, the dictionary includes both well-known characters like Thor and minor figures such as Gleipnir, the "fetter with which the wolf Fenrir was finally bound." It also includes further references about Viking and medieval Scandinavia, archaeology, etymology, the conversion of Iceland, other encyclopedias, and more.
