*Tribute to Luigi Ghirri: Christian Martinelli’s project seems to be one of those sound utopias art has lived on from time immemorial. Being able to capture, to seize also for a short time only, the evanescence and the transitoriness of these light inhabitants of our heaven, may seem an impossible enterprise. But it must be like this, because numerous artists have tried to grasp through art and observation the secret of clouds, their soul made of water, heaven and wonder.That ‘s the reason why Martinelli has travelled around the world, covered thousands of kilometres in search of places in which clouds become part of the landscape. But at the end of this long search his discovery consists in showing that the exotic aspect of geography keeps up with the observation of what we have in front of us. At the end it is true that there are latitudes which impress clouds different visions, fascinating singularities, but it’s also true that if you stay still and raise your eyes up to the sky, you can also find incredible and extraordinary things just where you are. How many clouds are we able to see from our usual standing, out of the window of our house? At the end observing them is like a zen training which forces us to meditation, to consider the absence of time. Martinelli has realized a metaphysical reportage, where time is practically absent because the space seems to renounce to be a sure reference point.John Ruskin wrote that painting clouds is really difficult, generally artists either represented them in a too hard way, transforming them into stones, or they painted them like thin brush-strokes as if they were gusts of fog. John Constable, some time before his landsman Ruskin, dedicated endless studies and paintings to these aerial elements of nature. Through his fotography Christian Martinelli was able to search for the magic and the mistery of these simple elements of nature, that mankind will never be able to domesticate and transform into uselessness. He gave duration and luminosity to the most changing, simple and fragile elements of the universe.Valerio Dehó
