Theory:

William Blake (\(28\) November \(1757\) – \(12\) August \(1827\)) was an English poet, painter and print maker. Blake is now considered a seminal figure in the history of English poetry. He was born in London. He was a boldly imaginative rebel in both his thought and his art. "A Poison Tree" was published as part of the Experience section of William Blake's best-known work, Songs of Innocence and Experience (first published in \(1794\), though Innocence was published individually a few years earlier). This book of poems is quite an educational work of poetic moralizing.
 
Few of his famous poems are:
  1. The Lamb
  2. The Tiger
  3. London
  4. And did those feet in ancient times
  5. The Sick Rose
