When studying the prehistoric times of the countries from the Carpathians and the Lower Danube, an ancient disappeared world, the cradle of the ante-Hellenic civilization, presents itself before our eyes. Behind the populations known in Greco-Roman antiquity under the name of Getae and Dacians, stretches back a long series of several thousand years, a buried history of some great events, whose importance had reached far beyond the horizon of this country, the history of a nation, genial, powerful and glorious, who, long before the Trojan times, had founded the first vast world empire, had founded the first cultural unity in Europe and had at the same time established a basis for the moral and material progress in western Asia and in north Africa.
