Which artist painted Water Lilies?

Monet, roughly 250 times over the last thirty years of his life, almost all of them of the pond in his own garden at Giverny - a garden he designed, had the stream diverted for, and employed several gardeners to maintain. He effectively built his subject and then painted it until he died.

The late ones were painted while he was going blind. Cataracts progressively yellowed and dimmed his vision through his seventies; the paintings from that period lost their blues and turned muddy red and brown, and he knew it was happening and destroyed a number of canvases in frustration. He finally had surgery on one eye in 1923, after which the blues came back - and some accounts suggest that with the lens removed he could see a little into the ultraviolet, which would mean the last works were painted by someone seeing colours nobody else can.

The largest are the Grandes Decorations, panels up to two metres tall and many metres long that he gave to the French state on the day after the Armistice in 1918, as a memorial - installed in two oval rooms in the Orangerie so a viewer stands surrounded with no corners and no horizon. He worked on them for years and insisted they not be shown until after his death.
