Act III, Scene III - Thunder and lightning. Enter Ariel, like a harpy, claps his wings upon the table, and, with a quaint device, the banquet vanishes.

ARIEL: (to Alonso, Antonio and Sebastian)
You are three men of sin, whom Destiny,
That hath to instrument this lower world
And what is in t, the never-surfeited sea
Hath caused to belch up youand on this island
Where man doth not inhabit, you mongst men
Being most unfit to live. I have made you mad,
And even with suchlike valor men hang and drown
Their proper selves. (some of the courtiers draw their swords)
You fools, I and my fellows
Are ministers of fate. The elements
Of whom your swords are tempered may as well
Wound the loud winds or with bemocked-at stabs
Kill the still-closing waters as diminish
One dowl thats in my plume. My fellow ministers
Are like invulnerable. If you could hurt,
Your swords are now too massy for your strengths
And will not be uplifted. But remember
For thats my business to youthat you three
From Milan did supplant good Prospero,
Exposed unto the sea, which hath requit it,
Him and his innocent child. For which foul deed
The powersdelaying, not forgettinghave
Incensed the seas and shores, yea, all the creatures,
Against your peace.Thee of thy son, Alonso,
They have bereft, and do pronounce by me
Lingering perdition, worse than any death
Can be at once, shall step by step attend
You and your ways; whose wraths to guard you from
Which here, in this most desolate isle, else falls
Upon your headsis nothing but hearts sorrow
And a clear life ensuing.
(Ariel vanishes in thunder)
