Ariel, Fetch me the hat and rapier in my cell

Prospero
Ariel,
Fetch me the hat and rapier in my cell.
Ariel exits and at once returns
with Prospero's ducal robes.
I will discase me and myself present
As I was sometime Milan.—Quickly, spirit,
Thou shalt ere long be free.

Ariel sings, and helps to attire him.

Where the bee sucks, there suck I.
In a cowslip's bell I lie.
There I couch when owls do cry.
On the bat's back I do fly
After summer merrily.
Merrily, merrily shall I live now
Under the blossom that hangs on the bow.

Prospero
Why, that's my dainty Ariel. I shall miss
Thee, but yet thou shalt have freedom. So, so, so.
To the King's ship, invisible as thou art.
There shalt thou find the mariners asleep
Under the hatches. The master and the boatswain
Being awake, enforce them to this place,
And presently, I prithee.
Ariel
I drink the air before me, and return
Or ere your pulse twice beat. He exits.
