I've been to the Tate on a number of occasions but on my last visit I was really fascinated with the display surrounding Poetry and Dream.
With an interest in surrealism so this part of the exhibition was really insightful.
"The displays in Poetry and Dream show how contemporary art grows from, reconnects with, and can provide fresh insights into the art of the past. The large room at the heart of the wing is devoted to Surrealism, while the surrounding displays look at other artists who, in different ways, have responded to or diverged from Surrealism, or explored related themes such as the world of dreams, the unconscious and archetypal myth. These displays also show how characteristically Surrealist techniques such as free association, the use of chance, biomorphic form and bizarre symbolism have been reinvigorated in new contexts and through new media, often at far remove from the intentions of their pioneers."
