The Norse Edda-poetry is a collection about the Norse gods and heroes. The collection is probably compiled somewhere in the 13th century. It contains poems from at least 4 centuries. The newest ones are probably written early in the 13th century and the oldest can be traced to the 9th century. Some poems may even be older. It is this colection of old verses that gives us some details about the faith that dominated the north of Europe before Christianity came. A good example is Völuspa; it contains among other thing the Norse creation myth. The most famous of the hero-poems are the ones dealing with Sigurd Fafnesbane and his deeds. The original of the collection is known as "Codex Regius" and is today kept in Iceland. Iceland is also the place were the author or editor worked.
