Artist Agnes Martin and Mental Illness

Agnes Martin painted in a minimalist style but considered herself an part of the abstract expressionist movement. She suffered from hallucinations, depression and was often hospitalized and eventually diagnosed with schizophrenia.

She used subtle color and meticulously drawn grids to create a calming effect. About her work she said "art is the concrete representation of our most subtle feelings.

Her work is also part of the Paul Allen billion-dollar art action at Christies later this month.
