Monet was deeply depressed about World War I which is reflected in his paintings of that period, including the one shown. His distress at the loss of life in his beloved country shows in a number of paintings from this period. In addition, he suffered from an eye ailment for which he had several surgeries. This problem seriously affected his color sense - of which he was acutely aware. Finally, his vision was restored.
The gardens are beautiful; even with a gazillion other people.
I did read about how dramatically his cataracts affected his vision. Apparently there were some canvasses that he went back and changed after his eye surgery, when he was able to perceive the colors better.
I read a little about his struggles during the war, too. Apparently, many people left the area entirely, and he lost many of his gardeners and household staff. He refused to leave his home and gardens, though, and stayed in Giverny, even though his gardens and home suffered for it. I can't imagine NOT feeling depressed when you see how war ravages your home and country!
There were so many more details I would have loved to have included. It was really difficult to narrow it down to a manageable article length!
Thanks for reading and commenting. It is good to hear from others who love his work, and have visited his home!
