 The Hebron tradition is also reflected in some medieval Christian sources, such as the account by Srewulf (CE 1102) who says that "the bones of Joseph were buried more humbly than the rest, as it were at the extremity of the castle".Though the traditional biblical date for the narrative of Joseph's life and death places him in Egypt in the middle of the Twelfth Dynasty, roughly comparable to the Hyksos invasion of Egypt, contemporary scholarship no longer accepts such a remote dating.The figure of Joseph itself is often taken to be a "personification of a tribe", rather than an historic person.
