The Younger Edda; Also called Snorre's Edda, or The Prose Edda

The Prose Edda, also known as the Younger Edda, is an Old Norse textbook written in Iceland during the early 13th century. The work is often assumed to have been, to some extent written, by the Icelandic scholar and historian Snorri Sturluson. Today, it is considered the fullest and most detailed source for modern knowledge of Norse mythology.
