Introduction to Monet: The most important work of Monet in his later years is the series "Water Lilies". After 1880, Monet became estranged from other Impressionist painters and built a small garden in Giverny, where he lived and painted. He likes to combine water and air with some artistic mood, which resulted in the "Water Lilies" series of paintings. Along the water, beautiful water lilies spread out to the distance of the lake. The painter used the reflection of the trees to highlight the layers of the flowers, which is a very creative idea. Monet devoted his whole body and mind to this pond and his water lilies, which became the theme of his paintings in his later years. For the next 27 years, he almost never left the subject.
