"We also have solid traditions to indicate that women found this tomb empty three days later. This is attested in all of our gospel sources, early and late, and so it appears to be a historical datum. As so I think we can say that after Jesus' death, with some (probably with some) certainty, that he was buried, possibly by this fellow, Joseph of Arimathea, and that three days later he appeared not to have been in his tomb" Bart Ehrman, From Jesus to Constantine Lecture 4, 2003
