<b>Claude Monet </b>
(1840 - 1926)

Haystacks is the common English title for a series of impressionist paintings by Claude Monet. The principal subject of each painting in the series is stacks of harvested wheat (or possibly barley or oats: the original French title, Les Meules à Giverny, simply means The Stacks at Giverny, obviously concerning stacks of straw). 

The title refers primarily to a twenty-five canvas series (Wildenstein Index Numbers 1266–1290) which Monet began near the end of the summer of 1890 and continued through the following spring, though Monet also produced five earlier paintings using this same stack subject. A precursor to the series is the 1884 Haystack Near Giverny (Pushkin Museum). 

The series is famous for the way in which Monet repeated the same subject to show the differing light and atmosphere at different times of day, across the seasons and in many types of weather. 
The series is among Monet's most notable works.

In May 1891, Monet hung fifteen of these canvases next to each other in one small room in the Galerie Durand-Ruel in Paris. An unprecedented critical and financial success, the exhibition marked a breakthrough in Monet’s career, as well as in the history of French art.
