<DIV><p>“Dada places before action and above all: doubt. Dada doubts everything. Dada is an armadillo. Everything is Dada, too. Beware of Dada”. While these words give a somewhat chaotic definition for this movement, whose name was taken at random from a dictionary, they are in fact a faithful expression of the intentions of its members. In 1916, in the heart of a Germany bruised by World War I, artist regrouped around the poet Tristan Tzara and chose, in a spirit of hope and rebellion, to demythologise art. For the rigor of drawing and harmony of colours, artists such as Picabia, Arp and Man Ray substituted movement and random luck. The work of art was no longer, therefore, the result of a particular plan or the expression of concepts, but rather the result of a game of chance. “Dada is neither a dogma, nor a school, but more a constellation of individuals and free facets”. It is these free electrons that the author captures here so as to help the reader understand how art evolved to produce such works as Macerl Duchamp's <i>Fountain</i>.</p></DIV>
