What are William Blakes poems about?

William Blake's poems can be seen as refering to his own religious views, which was to believe in God without the going to church. He thought the church was 'blackening' (From the poem called 'London').

It can also be seen in 'The Tyger' that he has a strong dislike towards the industrial revolution.

Many of his poems are sister poems (or couplet poems) which means they go together, for example, 'The Lamb' and 'The Tyger' or the two 'Nurse's song' poems. They often give different views of Innocence and Experience which can link to before and after the fall of mankind in the story of Eden with Adam and Eve.
