‘After Leonardo 73- 07’ is a large scale (10 x 3 meters) video installation made following invitation to eleven artists to create a work addressing another from art history and exhibited as ‘On History’. Its main concern is the way the meaning of an artistic icon, a monochrome reproduction of Leonardo’s la Gioconda, is changed by time and context. This new digital installation incorporates, as one part of its subject, aspects of a six-screen film first shown in 1973 exploring deterioration of the reproduction itself, physically present in the screening. It focussed on crazing depicted and actual in the reproduction and further deterioration through repeated re-filming from the screen during projection. The new digital installation doubles the length and the number of screens taking documentation of the film’s performances during the intervening years as raw material much as the film had previously treated the torn reproduction. Using high resolution, extreme close-up photography and layered superimposition, it reflects on the film medium as transformed by the digital context. The new work pays particular attention to the text of Sigmund Freud’s monograph ‘Leonardo da Vinci – a study in Psychosexuality’. This text, on the soundtrack and in visual superimposition, opens interpretation beyond Leonardo’s possible awareness. It becomes a paradigm for the way artworks are transformed through history by unpredictable methods of study, media and technologies available to future generations exploring the problematics of this transformation. ‘After Leonardo 73-07’ and the exhibition as a whole received extensive critical coverage in the Spanish national news and cultural press and was documented in a substantial catalogue (ISBN 978-84-89913-80-6). The work is not site specific and has since been presented at the Palais de Baux Arts, Brussels in June 2007 (see also output 3 Portraits and Particulars).
