As I read the end of the play, I could not understand why Prospero wanted to give up so much of his power when he talks about giving up his magic, "I'll break my staff, bury it certain fathoms in the earth, and deeper than did ever plummet sound. I"ll drown my book." pg 149 lines 63-66
How is it that a man who boasted of all his power and plan to take revenge is suddenly forgiving everyone and giving up what distinguishes him from every one else. Prospero is the only man who can control the spirits and convince them to do what he pleases, he uses his spells and charms to fool others and uses his magic on Caliban, Stephano, and Trinculo to stop their plot to kill him. He tells Ariel how sorry he feels and instead of satisfying his desire to kill them, he says he must feel compassion, forgive them and he lets them go. I wonder if his magic was ever a burden to him, otherwise, why would he want to give it up all of a sudden?
