French Painter.
Claude Monet (14 November 1840 – 5 December 1926) was a founder of French impressionist painting, and the most consistent and prolific practitioner of the movement's philosophy of expressing one's perceptions before nature, especially as applied to plein-air landscape painting. The term Impressionism is derived from the title of his painting Impression, Sunrise (Impression, soleil levant).

"Much closer to Monet's own atheism and pessimism is Schopenhauer, already introduced to the impressionist circle in the criticism of Theodore Duret in the 1870s and whose influence in France was at its peak in 1886, the year of The World as Will and Idea."

It's not clear, and probably not consciously intended by the atheist Claude Monet, but somehow the suggestion of a Cross lies there on her body."
