Historical memory is not just archives, libraries, masterpieces of art gathered in great museums and private collections. We all have our own historical memory. These are little nothings that have no value but are extremely important to us. Because as soon as we are confronted with them, memories of our childhood, the people around us, a life long since vanished resurface with the greatest clarity. The pot in which mother, in the summer, brought back the milk, the basin in which you were washed, the ABC book taken for the start of the first year of primary school, the first doll long since reduced to dust and forgotten: all this is our historical memory, our life.
