Thanks to Peter Campbell for this bit of Shakespeare:
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-capped 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 on, and our little life
Is rounded with a sleep.
- The Tempest, Act IV, scene i
