They are the thinking of a genius, the 500-year-old notes and drawings that reveal the extraordinary creative imagination of Leonardo da Vinci. But these are not preparatory works for his famous paintings such as the Mona Lisa or the Last Supper.They are the notebooks that demonstrate the great Renaissance master's other life as an inventor, engineer and scientist centuries ahead of his time.A new exhibition at the Victoria and Albert Museum, in London, is to show more than 60 precious leaves of da Vinci drawings, including works from the British Library, the Royal Collection and the V&A itself. Visitors to the show will be able to puzzle over sheets so fragile they rarely see the light of day.Martin Kemp, a professor of the history of art at Oxford University who has curated the exhibition, admitted many were "difficult" in comparison with da Vinci's better known works. But if the artist's explorations in geometry, anatomy and engineering prove daunting, highlights have been brought to life with animations commissioned from Cosgrove Hall, the company better known for creating Dangermouse.Professor Kemp hopes the combination will explain elements of his work that are often overlooked. "Most people have some sense that he was a universal man, but I think these should give reality to the idea," he said. "I'm confident that people will go away and think, 'Wow, there's even more to this person than I thought.'"
