Pierre Albert-Birot, Paul Dermée, Céline Arnauld, Francis Picabia, Tristan Tzara, Giuseppe Ungaretti, Pierre Reverdy, Marcel Arland, Joseph Delteil, Jean Painlevé and Robert Delaunay, among others. The other group, led by Breton, included Aragon, Desnos, Éluard, Baron, Crevel, Malkine, Jacques-André Boiffard and Jean Carrive, among others. Yvan Goll published the Manifeste du surréalisme, 1 October 1924, in his first and only issue of Surréalisme two weeks prior to the release of Breton's Manifeste du surréalisme, published by Éditions du Sagittaire, 15 October 1924. Goll and Breton clashed openly, at one point literally fighting, at the Comédie des Champs-Élysées, over the rights to the term Surrealism. In the end, Breton won the battle through tactical and numerical superiority. Though the quarrel over the anteriority of Surrealism concluded with the victory of Breton, the history of surrealism from that moment would remain marked by fractures, resignations, and resounding excommunications, with each surrealist having their own view of the issue and goals, and accepting more or less the definitions laid out by André Breton. Breton's 1924 Surrealist Manifesto defines the purposes of Surrealism. He included citations of the influences on Surrealism, examples of Surrealist works, and discussion of Surrealist automatism. He provided the following definitions: Expansion The movement in the mid-1920s was characterized by meetings in cafes where the Surrealists played collaborative drawing games, discussed the theories of Surrealism, and developed a variety of techniques such as automatic drawing. Breton initially doubted that visual arts could even be useful in the Surrealist movement since they appeared to be less malleable and open to chance and automatism. This caution was overcome by the discovery of such techniques as frottage, grattage and decalcomania. Soon more visual artists became involved, including Giorgio de Chirico, Max Ernst, Joan Miró, Francis Picabia, Yves Tanguy, Salvador Dalí, Luis Buñuel, Alberto Giacometti, Valentine Hugo, Méret Oppenheim, Toyen, Kansuke Yamamoto and later after the second war: Enrico Donati, Vinicius Pradella and Denis Fabbri. Though Breton admired Pablo Picasso and Marcel Duchamp and courted them to join the movement, they remained peripheral. More writers also joined, including former Dadaist Tristan Tzara, René Char, and Georges Sadoul. In 1925 an autonomous Surrealist group formed in Brussels. The group included the musician, poet, and artist E. L. T. Mesens, painter and writer René Magritte, Paul Nougé, Marcel Lecomte, and André Souris. In 1927 they were joined by the writer Louis Scutenaire. They corresponded regularly with
