Modern art includes artistic work produced during the period extending roughly from the 1860s to the 1970s, and denotes the styles and philosophy of the art produced during that era. The term is usually associated with art in which the traditions of the past have been thrown aside in a spirit of experimentation.
Although modern sculpture and architecture are reckoned to have emerged at the end of the 19th century, the beginnings of modern painting can be located earlier. The date perhaps most commonly identified as marking the birth of modern art is 1863, the year that Édouard Manet showed his painting Le déjeuner sur l'herbe in the Salon des Refusés in Paris. Earlier dates have also been proposed, among them 1855 and 1784. In the words of art historian H. Harvard Arnason: "Each of these dates has significance for the development of modern art, but none categorically marks a completely new beginning.
