Well, number one, since childhood I've been fascinated by and reading about ancient history, and number two, if I don't know the answer, I make up plausible lies. ;') The Metropolitan Museum has a special exhibition on the Egyptian Middle Kingdom, btw, for anyone interested and in geographical proximity. There's a statue of Amenemhat III, who was very likely the Pharaoh of Joseph.
Thanks for the info. I like reading about history. It will give me something to do with down time at work :)
