Bigge was a late inclusion in Unit One. His work was known to Nash but not to Nicholson, Moore or Coates. He was clearly influenced by Edward Wadsworth. Bigge wrote in the Unit One book, in which this painting was illustrated, that modern painting should avoid 'sentimentality' as well as 'Romanticism, Prettyness, charm, decorativeness, and preciosity' and look for 'Precision, clarity and simplicity'. He argued that an abstract painting should have a 'pure' content. Its forms must not be associated with 'function or symbol' and should appear solid but dispense with 'modelling and perspective'. It should be logically constructed and form and colour should be integrated.
