I totally understand what you mean. At first I thought Traditional Literature was classic stories. I did some research and basically this is what Traditional Literature is:
Traditional Literature (also known as Folk Literature) are stories passed down from generations to generations by oral storytelling. These stories include: Myths, Legends, Folktales, Fables, Fairy Tales, Tall Tales, and Nursery Rhymes. Traditional Literature is the foundation for the Fantasy genre.
I'm attaching a document I found online that helps further explain the genre. Hope this helps too!
