Guido von List was a very famous Austrian author and poet from the 1800s and early 1900s. He was known for writing books and poems about Germanic and Norse mythology and pagan religions. He also wrote about the history and culture of the ancient Teutonic people, which were a people group that lived in northern Europe thousands of years ago. List believed that Germanic people had a special connection to nature and believed in the spiritual power of nature. He believed in a form of paganism, which is an ancient form of worship that was practiced by people around the world. List also believed in a type of mysticism and magic known as "Runic" or "Armanic". This was a type of vision quest that would help people connect more deeply with nature and the spiritual world. List wrote books and poems to help spread his ideas about these ancient beliefs.
