That, if I then had waked after long sleep.
Will make me sleep again.

Stephano answers, like a modern millionaire:

This will prove a brave kingdom for me, where I shall have
my music for nothing.

Browning's Caliban is also something of a poet, and loves the Nature of
whom he is a child. We are not surprised when he

looks out o'er yon sea which sunbeams cross
And recross till they weave a spider web
(Meshes of fire some great fish breaks at times)

though the phrase is full of a poet's imagination, for so the living
earth would see and feel the sea. It belongs also to Caliban's nearness
to the earth that he should have the keenest of eyes for animals, and
that poetic pleasure in watching their life which, having seen them
vividly, could describe them vividly. I quote one example from the poem;
there are many others:

'Thinketh, He made thereat the sun, this isle,
Trees and the fowls here, beast and creeping thing.
Yon otter, sleek-wet, black, lithe as a leech;
Yon auk, one fire-eye in a ball of foam,
That floats and feeds; a certain badger brown
He hath watched hunt with that slant white-wedge eye
By moonlight; and the pie with the long tongue
That pricks deep into oakwarts for a worm,
And says a plain word when she finds her prize,
But will not eat the ants; the ants themselves
That build a wall of seeds and settled stalks
About their hole--

There are two more remarks to make about this poem. First, that
Browning makes Caliban create a dramatic world in which Miranda, Ariel,
and he himself play their parts, and in which he assumes the part of
Prosper. That is, Caliban invents a new world out of the persons he
knows, but different from them, and a second self outside himself. No
lower animal has ever conceived of such a creation. Secondly, Browning
makes Caliban, in order to exercise his wit and his sense of what is
beautiful, fall to making something--a bird, an insect, or a building
which he ornaments, which satisfies him for a time, and which he then
destroys to make a better. This is art in its beginning; and the highest
animal we know of is incapable of it. We know that the men of the caves
were capable of it. When they made a drawing, a piece of carving, they
were unsatisfied until they had made a better. When they made a story
out of what they knew and saw, they went on to make more. Creation,
