...Sleeping Beauty is a name thought of long before Disney got their haands on it, however Princess Aurora is their specific claim to the character...
In the original story, which was recorded by Charles Perrault earlier than the Grimm Brothers, Aurora was the name of the princess's daughter that she had with the prince after he came to awaken her.
Although I don't know much about the orginal story, I know in the century old ballet Sleeping Beauty, Princess Aurora is the name they use in the ballet, as well as alot of the same musical score!!!
This is also true. It was Tchaikovsky that shifted the name of Aurora to the princess. So Disney does not even have a specific claim to the name Aurora.
...To reverse the original question a little, I wonder if the Grimm Brothers had any heirs alive when Disney adapted these Grimm's Fairy Tales, such that Walt Disney had to get permission, or if the stories were in the public domain by that time.
The Grimms did not write Sleeping Beauty, they merely recorded it, as is true for the rest of their stories. And they were not the first in any case. So the Grimms had no rights in the first place.
...The brothers Grimm were not the creators of the classic stories, they were the first to publish them. Cinderella has a few "classic" variations. The prementioned "Toes and Heals" of the Gimm publication. An earlier version had Fur Slippers not Glass Slippers...
Charles Perrault also recorded Cinderella earlier than the Grimms. That version is in french. Some scholars think that Cinderella's slippers were originally made of fur, which makes a lot more sense. Fur in french is "vair", which is pronounced the same as the word for glass: "verre". Because it was a folk tale that was passed on by oral tradition, it could have easily changed somewhere along the line.
Cinderella has its roots in many varying folk tales going back as far as ancient Egypt (the story of "Rhodopis").
Sleeping Beauty also has roots that go way back.
A bit off topic: It is easy to see why Disney "cleaned up" the story to make it more palatable, and only used the first half for the same reason (and for length). In the original version (recorded by Giambattista Basile), the prince (actually a king - with a wife) has s_x with the princess, and she bears two children without waking up. Then one of the children sucked on her finger and drew out the piece of flax that put her to sleep and it was then she awoke.
In the second half (in Perrault's version), the princess has two children "L'aurora" and "Le Jour" (the dawn and the day - a girl and a boy). Their marrriage was kept secret from the prince's family until his father died, because his mother was decended from Ogres and the prince was afriad of what she would do. Then when his father died, and he became king, he brought the princess and his children home, and then when he had to go away to war, his mother tried to eat the girl and the boy. Whoa! There's more, but in the end prince/king comes home, the ogress mother dies and everyone else lives happily ever after.
In Basile's version it was the slighted wife and not the ogress mother who tries to eat his kids - jeesh! I'm usually critical of Disney not staying true to the story, but I kinda understand in this case!:lol:
