Norwegian mythology is a rich tapestry of stories and beliefs from ancient Norse culture, primarily centered around the pantheon of gods and goddesses. Key figures include Odin, the all-father and god of wisdom, and Thor, the god of thunder, who is known for his strength and protection of humanity. These myths often explore themes of creation, fate, and the struggle between good and evil. The mythology also features various creatures, such as giants, elves, and dwarfs, each playing significant roles in the tales. The cosmos is depicted as a tree called Yggdrasil, connecting different realms, including Asgard, the home of the gods, and Midgard, the world of humans.
