The title of this artwork, 'Where Angels Fear To Tread', is taken from  Alexander Pope's poem 'An Essay On Criticism' written in 1711. The phrase refers to the rash and foolish meddling of the inexperienced into matters that far exceed their understanding.
The artist has depicted two angels surrounded by warning signs pertaining to the dangers of nuclear biological and chemical research, suggesting that science itself is in danger of destabilising the natural balance of the earth.
