LONDON.- Tate Modern will present the first major retrospective of Joan Miró (18931983) to be held in London for almost 50 years. Opening on 14 April 2011, Joan Miró: The Ladder of Escape will bring together over 150 paintings, works on paper and sculptures by one of the twentieth centurys greatest artists. The exhibition will draw on collections from around the world to represent the astonishing breadth of Mirós output. It will also explore the wider context of his work, bringing to light the artists political engagement and examining the influence of his Catalan identity, the Spanish Civil War and the rise and fall of Francos regime. Miró was among the most iconic of modern artists, evolving a Surrealist language of symbols that evokes a sense of freedom and energy in its fantastic imagery and
