Our revels are now ended (The Tempest, Act IV Scene I)

Our revels are now ended: these our actors,
As I foretold you, were all spirits, and
Are melted into air, into thin air:
And, like the baseless fabric of this vision,
The cloud-capp’d towers, the gorgeous palaces,
The solemn temples, the great globe itself,
Yea, all which it inherit, shall dissolve;
And, like this insubstantial pageant faded,
Leave not a rack behind: We are such stuff
As dreams are made of, and our little life
Is rounded with a sleep.
