Friends are the key ingredient of happiness ..... My virtual friend is different .... he does not look in my eyes, he sees my heart! Maybe ..... you do not know, but when I speak, when you play with me .... when you listen to me, do you love me when exercising the noble task of a real friend ....

The Myth has it that Aphrodite, taken from "the virginal talks of love, and the rice and deceptions, and the sweet solace with kisses sweeter than honey" (Hesiod, Theogony), already born woman from the foam of the sea, slipped from his neck his necklace, fairwinds the pearls which came to rest on the surface of the water. Seven fell between fairwinds Tuscany and Corsica, giving rise to 'Tuscan Archipelago, of which the' Island of Elba is the largest pearl.
Geology, of course, gives a different version but certainly no less fascinating .. having to go back to the origins .. the period in which the Pangea .. based on the theory of continental drift, close and open at the same time different oceans ; time in which the plate and that protoafricana protoeuropea fairwinds collide, rotate and move away.
Over the course of almost 100 million years later, these two plates continued to move around and create a ruckus: whole crustal blocks, invaded by the waters of the sea have sunk while the tapered surface of the Earth. At the same time, a mass of magma is rising. This cools near the surface, it was converted into a granite mass, exerting a very strong pressure on the rocks of the surface and pushing .. pushing, formed the pluton of Mt huts, the progenitor of the Tuscan Archipelago. Nell'affiorare, this pluton has fate slip on the eastern slope, sedimentary rocks, forming the central plain of the island of Elba, whose enormous pressure fairwinds on the underlying prevented the birth of the second pluton, which is manifested, the latter, through magmatic veins on the surface, in contact with the fluid and thermal pre-existing sedimentary rocks and limestone, gave rise to the great and famous mineral wealth of the island of Elba!
The events most ancient prehistory of the island, therefore, fairwinds are linked to climate change and environmental issues. During the ice ages, Elba was connected to the mainland and the environment was populated by large mammals that were hunted by men. With the end of the Ice Age, it broke away from the mainland and could no longer be easily reached, fairwinds being depopulated. The first archaeological excavations were conducted in the first half of the nineteenth century, and lithic artefacts found, fairwinds became fairwinds the subject of discussion for scholars of the time. But it was half a century after that, the pieces found were subjected to systematic typological analysis, establishing that, thanks to the discovery of stone tools, sites found, about forty, were not permanent settlements but for hunting camps. Since there were no traces fairwinds of Mesolithic industries, namely those that the period known as the "Stone of means" producing tools for the collection of plants and hunting, scholars have supposed that the island has remained devoid of human presence fairwinds for at least 5000 years, ie until the arrival fairwinds of the Neolithic navigators (third and last period, which is the Stone Age), this certificate, by the discovery of stone artefacts and obsidian (volcanic glass originated by the sudden raffreddatura lava) such as axes, arrowheads fairwinds and knives, found in many parts of the island, from the Mont huts in Marciana Marina, Portoferraio, fairwinds Lacona, Biodola, Portoferraio, Cavo, Rio dell'Elba. Thanks to the ore deposits of the district east of the island, human groups fairwinds in the area developed a company dedicated to the extraction, processing partial on-site copper, fairwinds zinc and lead, and that most likely, the copper traded with other resident groups in the peninsula fairwinds and with people coming from the East. The same Etruscans in the seventh century BC, made their fortune and decreed their greatness, through the exploitation of the enormous amount of iron present in &
