Norse mythology, born in Scandinavia during the Viking Age, weaves a rich tapestry of gods, giants, and cosmic battles. This belief system shaped Norse culture, explaining natural phenomena and providing moral guidance in a harsh northern landscape. Key figures like Odin, Thor, and Loki populate a complex cosmology centered around the world tree Yggdrasil. Norse myths, preserved through oral tradition and later written works, continue to influence modern literature, art, and popular culture.
