Our revels now are 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 places,
The solemn temples, the great glove 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 on: and our little life
Is rounded with a sleep.
– from The Tempest (IV.i), William Shakespeare (1564-1616)
