All visitors to the “valley of the temples of Agrigento”, in Sicily, are struck by a double sensation, in fact, arrived on site, they are immediately struck by the fact that they are only there ruins : many stones covered in moss, some large capitals consumed by the wind that continually caresses the valley, and a few enormous ones columns laid out  as if they were resting on the damp ground...Then slowly everyone takes a  walk among the ruins and the crowds of visitors breaks, disperses: someone, approaching a column, hugging his shaft in an attempt to measure it she notices how enormous it is diameter; someone else, intrigued by a large white boulder, begins to walk around him and, with difficulty, recognize the features of a face made monstrous and unrecognizable by the enormous size of his features; yet another he trips on a small stone, turns back to pick it up and slowly with a finger he begins to remove the earth covering it, he notices a smoothing thin, precise, perhaps it is a small part of the frieze of the large temple... will bring home a piece of Greece, or perhaps simply a stone...
Just a few kilometers from the valley that is it opened onto the sea with the enormous temple of Zeus, the largest Doric temple of antiquity, more than 30 meters high, probably intended to impress i visitors with its size, there are instead impressive wreckage of some abandoned buildings over the years fifty in reinforced concrete: cracked walls, rust-rotted beams, iron irremediably bent protruding from the pillars, and broken tiles inside and indestructible toilets. The difference with the ruins of temples is disconcerting: in this place, reduced to a timeless space, concrete is broken with sharp edges and hurts the hands, the iron is eaten away by rust and everything that simulated unity is now decomposed, only one remains carcass whose parts are scattered everywhere, like pieces of a toy broken ; the resulting sensation is of decay, destruction, death. Nature will not accept those wreckage into itself since they are foreign to it and in enemies fund. They will stay there a little longer and then disappear forever.
The hardness of the concrete is made to resist stresses of loads, not those of time : in fact it deteriorates irremediably and in less than two hundred years. And so our homes and ours city. We won't leave any trace.
The people who built the temples and pyramids instead they dreamed of eternal constructions that would bear witness to theirs passage on earth and their civilization. But they knew that there would be time transformed and perhaps even corrupted those forms that were "too human" for be able to resist him.
The will of remain, therefore, it led them to consider it as an inevitable element and destiny itself of their works. They predicted its action, they mitigated its effects, their own attention was paid to the choice of materials capable of last; time would have smoothed, worn away, but never destroyed.
The passage in Greece from the wooden temple to that of marble, the use made in Rome of the "eternal brick" which imperceptibly centuries it returns to the land from which it comes, the grandiose Egyptian pyramids set like crystals among the desert sands, they tell of that precise will, since this is what they wanted: imprint their signs in nature changing it forever.
Those men who played with stones are now replaced by large construction companies, whose buildings are made of reinforced concrete they spread everywhere. They won't last long nor will the material that makes them up the germ of destruction that is inherent to it: “caementum” in Latin it means in fact scrap. And such they will become those agglomerations of houses and buildings built in a very short time and just as quickly destined to disappear.
The Egyptian pyramids, on the contrary, tired the centuries with their indestructible mass. And hands that don't exist yet they will caress the columns of the temple of Zeus in Agrigento perhaps forever.
Those stones - thought of as monuments to time - they resisted him, allowing history to become memory for the men and nature to gently reclaim its materials...
Blades of grass have grown among the ruins, moss he covered the stones...
