This May, the Carlo Colla & Figli marionette company hosts a special show, La Poesia della meccanica (The Poetry of Mechanics), in Milan to mark the 500th anniversary of the death of Leonardo da Vinci. Leonardo is, of course, recognised not only for his art but for his extraordinary prescience in the field of machinery, and what machine could be more simple yet more expressive than the marionette? www.marionettecolla.org
