With his own bolt; the strong-based promontory
Have I made shake and by the spurs pluck'd up
The pine and cedar: graves at my command
Have waked their sleepers, oped, and let 'em forth
By my so potent art. But this rough magic
I here abjure, and, when I have required
Some heavenly music, which even now I do,
To work mine end upon their senses that
This airy charm is for, I'll break my staff,
Bury it certain fathoms in the earth,
