"... let my Lamp at midnight hour,
Be seen in some high lonely Tow'r,
Where I may oft out-watch the Bear,
With thrice great Hermes, or unsphear
The spirit of Plato to unfold
What Worlds, or what vast Regions hold
The immortal mind hath forsook
Her mansion in this fleshly nook:
And of those Daemons that are found
In fire, air, flood, or under ground..."
from Il Penseroso by John Milton
