Hidden on the backs of canvases or scrawled on scraps of paper, doodles have allowed artists down the ages, from Michelangelo to Picasso, to test, explore and unleash their creativity. Rome's Villa Medici is showcasing this long-ignored facet of artistic production in a new exhibition spanning the period from the Renaissance to the present day. Entitled "Scribbling and Doodling - From Leonardo da Vinci to Cy Twombly", the unusual collection of nearly 300 original works ranges from playful and whimsical to transgressive and political. It brings to light delightful discoveries never intended for the public eye -- with some even in the most unexpected of places. IMAGES AND SOUNDBITES ARRANGED IN SEQUENCES
