Tyger, Tyger , Burning bright in the forest of the night.
In what distant deeps or skies.Burnt the fire of thine eyes?
What the hammer? what the chain, In what furnace was thy brain?
Did he smile his work to see ? did he who made the lamb make thee?
The speaker wonders how , once that horrible heart "began to beat", its creator would have had the courage to continue the job . Comparing the creator to a blacksmith , he ponders about the anvil and the furnace that the project would have required and the smith who could have wielded the them. When the job was done the speaker wonders how the creator would have left.
