Mrs. Peter Beckford
The sitter, Louisa Beckford, was often ill and is shown here making an offering to the Greek goddess of health, Hygeia. Her pallid grey face may not have been intentional though...
Instead of mixing his pigments with the standard linseed oil, Reynolds often experimented with unstable ingredients. As a result, some colours in his paintings, particularly his skin tones, have changed over time.
But is this faded Mrs Beckford the original or a clever copy?
