The Final Chalcholithic covers the time after the end of the classical stages of late chalcholithic culture complexes Kodzhadermen-Gumelnitsa-Karanovo VI, Krivodol-Salkuta-Bubani, and before the beginning of the protobronze cultures. This time is characterized by a drastic decline of the population in the plain lands of the Eastern and increment of the settlements in the semi-mountain and mountain zones of the Central Balkans and the Rilo-Rhodope area. On the current stage of research, most of the scholars think that this tendency was due to the climate changes that occurred in the end of the fifth millennium BC. They led to the termination of the KGKVI culture complex. KSB culture continued its existence but with a number of changes in its material culture, which indicated the transition to the following protobronze cultures. Those changes were part of complex transformations that probably had been provoked by the intensive connections between the Aegean, the Balkans and the Middle Danube.
The main reason for the intensification of the cultural contacts in this time can be seen in the large-scale exchange of cooper that was provoked by the metallurgic “boom” in the KSB area. The data for such contacts is significant. However the South Balkans didn’t take part in them. On the other hand there are lots of evidence about strong connections between the last region, the Central Balkans and the Rilo-Rhodope area. One of common features between them is the increase in the quantity of the spindle-whorls and the appearance of a new type – the so called “short conical” spindle-whorls. The appearance of the new type can’t be explained only with a common stylistic “fashion”, because the form of the spindle-whorls is directly related to their function. So, it can be concluded that there were partial changes in the spinning technique and the spinning process had increased its economic importance in the whole commented area.
The spinning technique depends on the used materials. Big spindle-whorls are suitable for spinning of long fiber raw materials (flax), and the small – for short fiber materials (goat hair, wool). In comparison with the most of the other Chalcolithic spindle-whorls the “short conical” can be considered as small.
The increment of the spinning process’s economic importance and the use of similar to the “short conical” spindle-whorls are also characteristic features for the mobile stockbreeding Chernavoda I culture. The existence of mobile pastoral groups in the Chalcolithic of the Central Balkan cultures was supposed long ago. So, it can be argued that the occurrence of the “short conical” spindle-whorls indicates the use of animal fibers in the textile production of those mobile pastoral groups.
The increment of spinning’s economic importance and the use of animal fibers in it was a supra-regional process. In the end of the V and in the IV millennium BC this was a characteristic feature for a wide region, including the Near East, the Aegean and the Balkans. This process underlies the selection of the first “wooly” sheep and the weaving of woolen textile.
