What style of art depicted or showed fleeting ideas rather than still form?

The style of art that depicted fleeting ideas rather than still form is known as Impressionism. This movement, which emerged in the late 19th century, focused on capturing the effects of light, movement, and atmosphere, often through loose brushwork and vibrant colors. Impressionist artists aimed to convey the essence of a moment, reflecting the transient nature of their subjects rather than detailed realism. Notable figures include Claude Monet and Pierre-Auguste Renoir, who emphasized the perception of a scene over its precise representation.
