Magic is more than mortal, though it tends to impact mortals. Ferdinand draws the connection that magic might also have a bit of the divine in it (otherwise it would be against God, and kind of blasphemous).

Prospero here uses his magic to protect him in a very simple way, though obviously he is much more powerful than this action implies. He is willing to use his magic as a dumb-show when necessary, in this case to convince Ferdinand that he's not playing around.

Prospero is not above using his magic to his own fancy. We are asked to think about the limitation of his power here – he can make spirits look like gods, but he has no access to the real gods. Is the implication that even Prospero's magic hits a glass ceiling when it comes to the divine?
