The relation of mental disorders with technical treatments in the work of the artist "Vincent van Gogh"

It is paradoxical that the relation between genius and mental illness is 
clearer than the relation between genius and intelligence and more 
mysterious at the same time. The relation between psychological suffering 
and creative ability has been emphasized for centuries; As the Greek 
philosopher Aristotle said, “No great mind has ever existed without a touch 
of madness.” Perhaps Vincent van Gogh is the most famous example of a 
creative genius who was mentally ill. This research deals with an analysis 
of the works of the artist "Van Gogh" through his psychological crises and 
the limits of research in Europe in the twentieth century. It follows the 
historical-analytical approach based on analyzing the works of the artist 
"Van Gogh" and sheds light on his upbringing, which had a role in his 
suffering, and discusses some of his disorders that explain the reasons for 
his technical treatments of line, shape and color in his artworks, which led 
to identifying research problems in The library's scarcity of research and 
studies that help interpret artworks according to the artist's psychological 
state.
