Okay, I read in A Handbook To Life In Ancient Greece that the Classical Hellenic period there were no magicians. Now what I would like to know is what was the view of the Hellenists about magic, witchcraft, stuff like that? I read that it wasn’t considered okay to practice witchcraft. So what is your take on this?
