Dali paintings are covered in full here with an article aiming to detail three of his most famous paintings; including a good amount of detail on what each symbolize, and how they fit into Dali's overall art career which consisted of a whole plethora of innovation and quality in many different media, over many years.
Dali was born in Spain, 1904, and counted Cubism, Dada & Surrealism as his main art movements in a career that spanned his whole life up until his death in 1989. It is quite difficult to condense his many achievements into two or three main works , but we will do so as follows.
The Persistence of Memory, often called Melting Clocks, is the most famous painting by artist Salvador Dali. It is now stored at the Museum of Modern Art (MoMA) in New York City, and has been there since 1934.
Soft Construction with Boiled Beans was created by Dali in 1936, and is one of his best known Surrealist paintings. It was one of Dali's most political paintings, in this case attacking the subject of the Spanish civil war. Spanish artists regularly spoke out about the war at that time, and many had to leave the country temporarily in order to continue their campaign. The Soft Construction with Boiled Beans painting is now stored at the Philadelphia Museum of Art.
Leda Atomica is a 1949 Salvador Dali painting which shows Leda, a mythical queen, as the main subject. Leda is actually a portrait of Salvador Dali's wife, Gala, who's sat down in the painting. It is now to be found in the Dali Theatre and Museum in Figueres.
There are possibly 10 or 20 paintings that could be included as a list of Dali's best, and much of his success was in the variety of his work, as well as the high quality that he maintained throughout.
