the 1920s. Dalí was influenced by many styles of art, ranging from the most academically classic, to the most cutting-edge avant-garde. His classical influences included Raphael, Bronzino, Francisco de Zurbarán, Vermeer and Velázquez. Exhibitions of his works attracted much attention and a mixture of praise and puzzled debate from critics who noted an apparent inconsistency in his work by the use of both traditional and modern techniques and motifs between works and within individual works. In the mid-1920s Dalí grew a neatly trimmed mustache. In later decades he cultivated a more flamboyant one in the manner of 17th-century Spanish master painter Diego Velázquez, and this mustache became a well known Dalí icon. 1929 to World War II In 1929, Dalí collaborated with Surrealist film director Luis Buñuel on the short film (An Andalusian Dog). His main contribution was to help Buñuel write the script for the film. Dalí later claimed to have also played a significant role in the filming of the project, but this is not substantiated by contemporary accounts. In August 1929, Dalí met his lifelong muse and future wife Gala, born Elena Ivanovna Diakonova. She was a Russian immigrant ten years his senior, who at that time was married to Surrealist poet Paul Éluard.

The exhibition was a commercial success but the critical response was divided. In the same year, Dalí officially joined the Surrealist group in the Montparnasse quarter of Paris. The Surrealists hailed what Dalí was later to call his paranoiac-critical method of accessing the subconscious for greater artistic creativity. Meanwhile, Dalí's relationship with his father was close to rupture. Don Salvador Dalí y Cusi strongly disapproved of his son's romance with Gala and saw his connection to the Surrealists as a bad influence on his morals. The final straw was when Don Salvador read in a Barcelona newspaper that his son had recently exhibited in Paris a drawing of the Sacred Heart of Jesus Christ, with a provocative inscription: "Sometimes, I spit for fun
