I can't believe I got so excited that people were commenting on this thread!  Silly moi!  It used to be a common joke when I was a child to say to our Christian friends, "Easter's cancelled!  They found the body!"  Of course I had no idea at the time what that meant!  My original idea was to compare how Robin Hood went from a real, documented person  Robert Hode to Robin Hood in a few hundred years, with Joshua be Pantera over five hundred years.  Robert Hode was a real person; Robin Hood was not.  Jesus ben Pantera was a real person; Jesus of Nazareth was not.  No takers?  Nobody?
