I see
The gates of what they call their Paradise
Guarded by fiery-sworded Cherubim,
Which shut them out - and me: I feel the weight
Of daily toil, and constant thought: I look
Around a world where I seem nothing, with
Thoughts which arise within me, as if they
Could master all things - but I thought alone
This misery was mine.
(Lord Byron - Cain)
