O.k. Let's work this out logically:
--A teen-aged male magician in ancient Egypt put to death for his magic. What must THAT act have been like?
Here's how the act must have looked, if you were there, at the palace on the edge of the Nile, thousands of years ago...
He entered carrying a dapper walking stick with-which he momentarily danced before turning it into two snakes. This led into a nice ankh on snake routine with a borrowed ankh.
He did rocks across; torn and restored papyrus; multiplying dung-balls with multi-scarab climax; the old (even at that time) croc-in-the-reeds trick; sands of the desert...
That seems like a pretty tame line-up to me, of course much of our world is different than it was during ancient Egyptian times.
Unless he used inappropriately off-color humor in mixed company (as certain teen-aged magicians have been known to do at times, I hear) what trick could have possibly got him killed? [Historians suggest it may have been The Balducci levitation. Here's how the scene may have played out: "Aiiee!! He's soaring like a hawk 2" above the sand! He must be a witch! Kill him!!"]
Or, did he do the bra trick with Pharoah's daughter? --Did he blow an eclipse prediction? --Did his lips move when he was making the statue of Ra talk?
Any further scholarship will be greatly appreciated.
