Norse mythology in popular culture
The Norse mythology, preserved ancient Icelandic texts such as the Poetic Edda, the Prose Edda, and other lays and sagas, was little known outside Scandinavia until the 19th century. With the widespread publication of Norse myths and legends at this time, references to the Norse gods and heroes spread into European literary culture, especially in Scandinavia, Germany, and Britain.
