Why were Claude Monet’s Haystacks paintings successful when they were exhibited in 1891?

When Claude Monet’s Haystack series was exhibited in 1891, the show was a triumph for several reasons. Critics were particularly impressed by Monet’s unique ability to render fleeting light effects, which he referred to as "instantaneity"—the "envelope" of light that unifies a scene for a brief moment before changing.12

Beyond his technical mastery of light, audiences and critics responded positively to the French rural subject matter. The paintings, which depicted grain heaps located behind the artist's home in Giverny, were viewed by many as symbols of the fertility and prosperity of the French agricultural landscape. By intending for the canvases to be viewed together, Monet provided a cohesive experience that allowed viewers to appreciate his meticulous exploration of how light, across different seasons and times of day, dynamically altered the appearance and structure of a seemingly mundane subject.12
