"A Klee painting named "Angelus Novus" shows an angel 
looking as though he is 
about to 
move away from something he is fixedly contemplating.  
His eyes are staring,
his mouth 
is open, 
his wings are spread.  This is how one pictures 
the angel of history.  

His face is turned toward the past.  

Where we perceive a chain of events, he sees 
one single catastrophe 
which keeps piling 
wreckage upon wreckage and hurls it in front of 
his feet.  

The angel would like to stay, 
awaken the dead, 
and make whole what has been smashed.  
But a storm is blowing from paradise; it has got caught in his wings 
with such violence that
the angel can no longer close them.  

This storm irresistibly propels him into the future 
to which his 
back is turned, while the pile of debris before him grows 
skyward.  

This storm is what we call 
progress."
- Walter Benjamin.
