An Exhortation, by Percy Bysshe Shelley

 

Chameleons feed on light and air:
   Poets' food is love and fame:
If in this wide world of care    
   Poets could but find the same 
With as little toil as they,    
   Would they ever change their hue    
   As the light chameleons do, 
Suiting it to every ray       
      Twenty times a day? 

Poets are on this cold earth,    
   As chameleons might be, 
Hidden from their early birth    
   In a cave beneath the sea; 
Where light is, chameleons change:    
   Where love is not, poets do:    
   Fame is love disguised: if few 
Find either, never think it strange       
      That poets range. 

Yet dare not stain with wealth or power    
   A poet's free and heavenly mind: 
If bright chameleons should devour    
   Any food but beams and wind, 
They would grow as earthly soon    
   As their brother lizards are.    
   Children of a sunnier star, 
Spirits from beyond the moon,       
      Oh, refuse the boon!
