Dragon Legends

Once upon a time, a young, beautiful princess was trapped in a castle tower. Suddenly she was in grave danger when a fire-breathing dragon flew toward her tower window. But a knight in shining armor came to her rescue, narrowly avoiding a fiery death as he slayed the dragon just as it swooped down. Everyone is familiar with these classic dragon stories, but is there any truth to the supposed fairy tales and legends like Beowulf, Chinese dragons, or Nessie?
