One of the more odder secrets of the Spanish Civil War has <a href="http://www.guardian.co.uk/spain/article/0,2763,883074,00.html">come to light</a>, through the research of historian Jose Milicua, who has discovered that anarchist forces commissioned specially built jail cells come torture chambers, based on the principles of surrealist art. Beds were placed at a 20 degree angle, making them near-impossible to sleep on, and the floors of the 6ft by 3ft cells was scattered with bricks and other geometric blocks to prevent prisoners from walking backwards and forwards. Prisoners were forced to stare at the walls, which were curved and covered with surrealist patterns of cubes, squares, straight lines and spirals which utilised tricks of colour, perspective and scale to cause mental confusion and distress. Lighting effects gave the impression that the dizzying patterns on the wall were moving. The tribunal also claimed that other Republican jails forced prisoners to watch the infamous eye-cutting scene in Bunuel's Un Chien Andalou. As initially bizarre as this may seen, it could be argued that Laurencic was an impressive pioneer in psychological torture, as many of the techniques of mental confusion, sensory depravation and the use of a level of physical discomfort, that while not approaching actual physical torture, can cause profound mental distress, are utilized by police and intelligence forces, across the globe.
