Mr. Mybug compares Branwell Brontë to Thomas Chatterton (1752-1770), an English poet who died of arsenic poisoning in what was possibly a suicide attempt. The poet John Keats wrote an elegiac sonnet to his memory in 1815:
O Chatterton! how very sad thy fate!
Dear child of sorrow - son of misery!
How soon the film of death obscured that eye,
Whence Genius wildly flashed, and high debate.
