Miro was an artist and sculptor born in Barcelona. He "studied" the works of Van Gogh, Gaugin, Monet, and others. His parents did not want him to be an artist, but after a nervous breakdown suffered from the depression that came from working in an office, they gave it. Influenced by VanGogh and the expressionists, he eventually became known for being a Surrealist painter. He experimented with his art, sometimes alienating other Surrealist painters. Later in his life he painted on paper, and even worked as a sculptor, both in ceramics and later in bronze. By some he is considered the greatest Surrealist painter ever.
Miro studied at La Lonja School of Fine Arts in Barcelona where his early influences included church frescos, Fauvism, and Cubism. A love for colors that were unmuddied came from Fauvism, while Cubism influenced a love of shapes. His national Catalan folklore combined with Roman frescos to give playfulness to what became surrealistic painting.
Actually, Picasso was an artist that Miro scorned as he thought Picasso's paintings were rather bourgeois. It is important to remember that, in terms of Miro's identity, he was actually a Catalan, and that he lived at the time of Franco and spent the Civil War years in exile as Franco persecuted Catalan intellectuals.
Miro was a talented, experimental artist. The influence of Picasso is clear in his work. In addition to paintings, ceramics and sculptures, he also painted murals. There is even a museum dedicated to his work in Spain, in his birth city.
Joan Miro was also influenced by poets and writers. Under the influence of poets and writers, he developed his unique style which can be described as organic forms and flattened picture planes drawn with a sharp line.
