Salvador Dali's exploration of the depths of the subconscious mind in his paintings and his powerful images tapped into the fantasies, dreams, fears and hallucinations of entire generations, and he should be remembered as a consummate draughtsman, and a pioneer of Surrealism. An artist who made modern art popular and accessible. “The Persistence of Memory” is for good reason, the most celebrated surrealist canvas ever painted. Created long before his descent into self-parody, it really is the work of a crazy genius.
