Claude Monet - Grainstack, Impression in Pinks and Blues 1891
It is difficult to imagine a more iconic Impressionist masterpiece than
the artwork, Monet's 'Grainstack' (Meule) 1891, possibly the most
vibrantly colorful of all the painter's slightly more than thirty variations
on this motif that revolutionized modern art. Monet painted six of his
grainstacks ("meule" in French) compositions already in 1888, and
then fully realized his obsession with the subject starting in the
autumn of 1890. - ArtsViewer.com
