Impressionism is a French pictorial movement born around 1860 in Paris and then developed all over the world. Thanks to the invention of the colored tubes, the impressionists painted en plein air, that is in the open air, with a rapid technique that allowed to complete the work in a few hours and capture the different aspects of sunlight. A characteristic of Impressionist painting is the interest of color rather than drawing; the prevalence to paint one's emotions; the use of spatula painting in the creation of finished surfaces with an irregular appearance. The most important artists of Impressionism are: Claude Monet, Edgar Degas, Alfred Sisley. Of particular importance were also the Italian impressionists called "macchiaioli" whose masters are Silvestro Lega and Telemaco Signorini.
