After this, William Blake describes the imagined process of how the creator of the tiger makes the tiger. He uses very industrial language -
"What the hammer? What the chain?
In what furnace was thy brain?"
This reflects the fact that at the time the poem was written the Industrial Revolution was happening in England and people were re-imaging what it means to create, using big machines and lots of fire. The Industrial Revolution may have helped people to think about their own power of creation and to question if they could really talk about the world as having been made by just one being. Blake's final question to the tiger echoes this,
"Did he who made the lamb make thee?"
The tiger and the lamb are such different animals - were they really made by the same creator? Can we allow the tiger and the lamb to both be a part of the same world, a world of paradox and yet still somehow one beautiful whole?
The poem - 'The Tyger', is from 'Songs of Experience' which is a counterpart to 'Songs of Innocence'. In 'Songs of Innocence' is the counterpart poem to 'The Tyger'; 'The Lamb'. This is another poem where William Blake questions the power of immortal creation.
If you want to get more insight into this poem I suggest you also read 'The Lamb', and maybe some more of William Blake's work.
