Snorri Sturluson (1179-1241), poet and politician, is thought to have written the Prose Edda, or Snorri‘s-Edda around 1220. The book, which is in four parts, is a text book of poetics as well as telling stories of the Pagan gods and their endeavours.
The Prose Edda is preserved in several manuscripts, the oldest dating back to around 1300 and the newest from around 1600.
The Prose and Poetic Edda are the main sources of the pagan religion, Norse mythology and the world view of people in North Europe at this time.
