Have you heard about the Icelandic sagas? They were taken down in writing by learned Icelanders at the beginning of the 13th century. Some of the sagas tell ancient Scandinavian history, others of the lives of powerful people or ruling families.
The best known of the Icelandic writers is Snorre Sturlason (1179-1241). His greatest work is Heimskringla, which tells of Scandinavian history until the 13th century. He has also written the Younger Edda. The Edda teaches the art of poetry and story-telling.
The Older Edda describes old Scandinavian heroes and gods. We do not know who wrote it. The Older Edda contains the poem Völuspa, or the Prophecy of the Völva, which tells us about the creation and end of the world and of the creation of a new world. A Völva is a fortune-teller.
