I thought a sarcophogus was something you put the coffin in. From the looks of the one Vivian has, it is just a glorified coffin where the body goes directly in it. It was all lined like a coffin.
Oops, I guess not, I looked it up and it said, a stone coffin. Funny, when you see them in movies and they take the lid off, there is usually another coffin inside. Gee, for once the writers got it right! But the worst part, I was wrong!!!
