Where did Wagner get his inspiration for the Ring of the Nibelungenlied?

Wagner's inspiration for The Ring of Nibelungenlied came from his own experience and reading experience. In 1815, he visited Karlsruhe in southern Germany, where he saw a mysterious city-Nibelungenlied. He was deeply attracted by its beauty and mystery and began to explore the history and culture of the city. He also heard about the legend of the ring, which was very popular in the German-speaking region. It was called the "Nibelungenlied Ring" or "Karlsruhe Ring". This ring was said to be a mysterious item that could grant people extraordinary powers but at the same time, destroy everything. Wagner was deeply attracted by the legend and began to imagine a world made up of rings, a world full of magic and power. Therefore, the inspiration for The Ring of Nibelungenlied came from Wagner's exploration of Nibelungenlied and the legend of the ring. In his novel, he created a world full of magic and power, describing an adventure story full of desire and conflict. This story became one of the most famous novels of the 19th century.
