Claude Monet was a French impressionist painter who is considered one of the most influential artists of the 19th century. He is best known for his series of paintings depicting the same scene at different times of day, which he called his "series paintings." Monet's work was characterized by its use of light and color to capture the changing effects of natural light on a subject. He often painted outdoors, and his works were filled with vibrant colors and bold brushstrokes. Monet's work had a profound influence on modern art, inspiring many other artists to explore the use of light and color in their own works.
