"Ye elves of hills, brooks, standing lakes, and groves; And ye that on the sands with printless foot Do chase the ebbing Neptune, and do fly him When he comes back; you demi-puppets that By moonshine do the green sour ringlets make, Whereof the ewe not bites; and you whose pastime Is to make midnight mushrooms, that rejoice To hear the solemn curfew; by whose aid — Weak masters though ye be — I have be-dimm'd The noontide sun, call'd forth the mutinous winds, And 'twixt the green sea and the azur'd vault Set roaring war. To the dread rattling thunder Have I given fire, and rifted Jove's stout oak With his own bolt; the strong-bas'd promontory Have I made shake, and by the spurs pluck'd up The pine and cedar. Graves at my command, Have wak'd their sleepers, op'd, and let 'em forth, By my so potent art. But this rough magic I here abjure; and, when I have requir'd 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, And, deeper than did ever plummet sound, I'll drown my book."
