The story of Beren and Lúthien was one of Tolkien’s particular favourites. He imagined his wife Edith as his Lúthien, inspired by a time when she danced for him in the woods. When she died he had the name Lúthien inscribed on her gravestone, and after his own death he was buried with her, under the name Beren. The engravings read:
Edith Mary Tolkien
John Ronald Reuel Tolkien
Similarities have been noted between the story of Beren and Lúthien and the Welsh tale of Culhwch and Olwen.
