What inspired Claude Monet to paint?

Water lilies, gardens, the color of the light changing during the day, Eugene Boudin, the moment, the landscape, the shores of Brittaney, etc..

- I want to paint the air in which the bridge, the house and the boat are to be found - the beauty off the air around them, and that is nothing less than the impossible.
