This following series of drawings on found « arabesque » paper, probably torn up from an old book, are five house interiors attempting to cartography a vague souvenir of a once visited house. When I was in NY, I literally transferred to a new house in Liège. I than tried to remember my future new house, by using the ancient theory of mnemonic principles and techniques, used in order to organize memory impressions, improve recall. The art of architectural mnemonic is first described by the anonymous Ad Herennium but also by Cicero and Quintilien. According to the account in the Ad Herennium (Book III) backgrounds or ‘places’ are like wax tablets, and the images that are ‘placed’ on or within them are like writing.
