The Spring (or La Source) is a large oil painting created in 1912 by the French artist Francis Picabia. The work, both Cubist and abstract, was exhibited in Paris at the Salon d'Automne of 1912. The Cubist contribution to the 1912 Salon d'Automne created a controversy in the Municipal Council of Paris, leading to a debate in the Chambre des Députés about the use of public funds to provide the venue for such 'barbaric' art. The Cubists were defended by the Socialist deputy, Marcel Sembat. This painting was realized as Albert Gleizes and Jean Metzinger, in preparation for the Salon de la Section d'Or, published a major defence of Cubism, resulting in the first theoretical essay on the new movement, Du «Cubisme». The painting forms part of the permanent collection of the Museum of Modern Art,
