Nordic mythology includes Icelandic epics and which epics?

Nordic myth is a unique myth system in Scandinavia, which was first popular in Norway, Denmark and Sweden, and spread to Iceland and other places with a group of immigrants going north around the 7th century. In the Middle Ages, Christianity prevailed throughout Europe. Due to the strong political blow, most of the works recording Nordic myths were regarded as heresies and burned. So far, the Icelandic epic Eda and the Germanic epic Song of Nibelungen have been well preserved.
