Bryan Charnley was an artist and schizophrenic patient, he started the 'Self Portraits Series' in 1991 and was encouraged by a friend to keep a diary that explained the imagery of the portraits. You could call it an experiment of sorts as the series openly describes the graded sufferings he was oppressed by, as he struggled with his medication (see the enclosed linked for more information). The portraits describe his paranoia, depression, and psychosis accurately.

There was no commentary for the penultimate and final portraits which do not even have faces on them, but this 'map' shows very well the paranoia Charnley was facing as he feels surrounded by enemies, despite 'Hope' being at the centre.
