Tiger, Tiger

TIGER, tiger, burning bright  
In the forests of the night,  
What immortal hand or eye  
Could frame thy fearful symmetry?  
 
In what distant deeps or skies         
Burnt the fire of thine eyes?  
On what wings dare he aspire?  
What the hand dare seize the fire?  
 
And what shoulder and what art  
Could twist the sinews of thy heart?  
And when thy heart began to beat,  
What dread hand and what dread feet?  
 
What the hammer? what the chain?  
In what furnace was thy brain?  
What the anvil? What dread grasp  
Dare its deadly terrors clasp?
