Geology.—The axis of the Transylvanian Alps consists of sericite schists and other similar rocks ; and these are followed on the south by Jurassic, Cretaceous and Early Tertiary beds. The Jurassic and Cretaceous beds are ordinary marine sediments, but from the Cenomanian to the Oligocene the deposits are of the peculiar facies known in the Alps and Carpathians as Flysch. Farther north, the Flysch forms practically the whole of the Rumanian flank of the Carpathians. Along the foot of the Car pathians lies a broad trough of Miocene salt-bearing beds, and in this trough the strata are sometimes horizontal and sometimes strongly folded. Outside the band of Miocene beds the Sarmatian, Pontian and Levantine series, often concealed by Quaternary deposits, cover the great part of the Danube plain. Even the Pontian beds are sometimes folded. In the Dobrudja crystalline rocks, presumably of ancient date, rise through the Tertiary and recent deposits to form the hills which lie between the Danube and the Black sea.
Rumania is rich in antiquities of all periods from the Neolithic to the Roman but no scientific archaeological work can be said to have been done before 1900 when Prof. Tocilescu published the results of his surveys of Roman Dacia. Excavation by Ru manians did not begin before The Neolithic period is hard to distinguish from the Chalco lithic but in general it is abundantly clear that Rumania in the first half of the third millennium B.C. formed part of a homo geneous region in which Bulgaria, Thrace, Thessaly and the Ukraine as far north as Kiev were included. This culture is distinguished by a remarkable painted pottery of high artistic quality in design and shape. The people of this area and period have, for convenience been called the people of the "Black Earth Region" because the soil is rich and alluvial and because those living upon it at this period were largely agriculturalists.
The most important sites in Rumania hitherto examined are Cucuteni near Jassy where abundant remains have been found of two periods of this culture, Erosd in Transylvania and Brasov (Kronstadt), and some sites (excavated by Germans during the World War) near Cernavoda on the Danube. The culture so revealed is one of the most remarkable that developed in Europe in the early prehistoric period. It is thought by some to have oriental affinities with regions so far afield as Turkistan and Honan in China, where remarkably similar pottery is found. In any case the "Black Earth Culture" came to an abrupt end about 2000 B.C. and was replaced by a culture coming from the north-east, equipped with weapons of war. The Bronze Age that ensued develops rapidly and concentrates mainly in the western half of Transylvania and the Hungarian plains. It is of great artistic merit and some of the finest products of the European Bronze Age in gold and bronze come from Transylvania. In habited sites are numerous but not large and the gold of Transyl vania seems certainly to have been worked on a large scale. There was a nobility and a subordinate or serf population and the ac coutrement of the nobility and their gold ornaments and plate form an outstanding feature of the civilisation they represented. The fioruit of this Bronze Age seems to have been about the fifteenth century B.C. and the Hungarian plain seems to have been the breeding-place for movements that extended far and wide. Bronze swords of Danubian type from these regions are found during the fourteenth and thirteenth centuries penetrating, perhaps more as signs of invasion than as elements of trade, as far afield as Mycenae, Egypt, Cyprus and Crete. The makers of the swords seem to have been the peoples who were gradually pressing down southwards into the Mediterranean and who subsequently were responsible for northernisation of the Minoan world. Their gold may have reached the wealthy cities of the Mycenaean mainland. Certainly they were in close touch with Troy and Anatolia.
