Norse myths are a collection of stories from ancient Scandinavia that explain the beliefs and traditions of the Norse people. These tales feature a variety of gods, goddesses, and mythical creatures, such as Odin, Thor, and Loki. They often explore themes of creation, destruction, and the struggle between good and evil. The myths are primarily found in texts like the Poetic Edda and the Prose Edda, written in the 13th century. They describe the nine worlds, including Asgard, the home of the gods, and Midgard, the world of humans. These stories have influenced modern literature, art, and popular culture.
