Tanngnjóstr is a mythical goat from Norse mythology, known for pulling the chariot of the god Thor. This creature is often depicted as a powerful and magical being, capable of providing sustenance through its milk. Tanngnjóstr, along with his companion Tanngrisnir, symbolizes strength and resilience in the face of challenges. In the tales, Tanngnjóstr's ability to regenerate makes him a unique figure, as he can be killed and eaten, only to be revived the next day. This cycle of life and death reflects the themes of renewal and the interconnectedness of nature in Norse beliefs.
