Anthropomorphic stone stelae of monumental dimensions dated to the 4th and 3rd millennia BC have been found in southern Europe between the Atlantic Ocean and the Caucasus. They are understood as symbolic human representations the size of which arises out of a new self-awareness of humankind in the world. Anthropomorphic stelae are one of many innovations appearing during this epoch. Other innovations are copper metallurgy and tools, in particular weapons and jewellery, as well as the wheel, the wagon, and the plough drawn by animals. These innovations are depicted on stelae; what is more, the stele itself is an innovation in which the other changes are bundled. Comparable stylistic features of stelae in different areas demonstrate far-reaching contacts. Often the origin of anthropomorphic stelae is seen in the Russian steppes, with the archaeogenetically proven migration from east to west being the cause for the building of stelae in central and western Europe. However, the oldest known stelae apparently originate in western Europe. The impulses behind the dissemination of innovations must have emanated from continuous exchange relations, but the migration in the 3rd millennium bce did not bring with it the idea itself of anthropomorphic stelae. Nowadays the question about the function of stelae is usually answered with the representation of ancestors. When anthropomorphic stones keep the memory of common roots alive, they serve the building of identity.

Innovation transfer can be described as a process of communication and integration. Its success depends on two conditions: first, the information flow itself and, second, the acceptance and implementation of this information. In this article, it is assumed that both aspects are influenced by certain factors that can stimulate or constrain the transfer of innovation. This hypothesis is tested in a case study concerning the spread of copper metallurgy in Central Europe. A contextual analysis shows that its transmission can be reconstructed as a slow integrational process. Further, the spread of copper metallurgy occurred in fits and starts, with repeated breaks that, in some cases, lasted for several hundred years. These halts are key for analysing the mechanisms of innovation transfer. In this context, the role of those variables which influenced this transfer will be analysed.

This study seeks to discuss the origins and early spread of metal technology in the central Mediterranean region. Neolithic and Copper Age evidence of metal-working and metal-using is first reviewed. It is claimed in particular that copper tools were first used, and probably also made, south of the Alps in the late Neolithic, and that complex polymetallic metallurgy developed in the early Copper Age after a short-lived intensification phase in the final Neolithic. In the second section, current models explaining the emergence of metallurgy in this region are then discussed, and a new proposal is put forward. This claims that metal technology, coming from eastern Europe, was imported into the whole of the east-central alpine region in the third quarter of the fifth millennium BC. Thence, it would have swiftly spread throughout northern Italy, central Italy, and Sardinia, and would have reached Corsica, southern Italy, and Sicily somewhat later. Finally, it is argued that the Copper Age metalworking communities dwelling in the western part of the central Mediterranean, and especially those located in west-central Italy, would have played a key role in transmitting knowledge of extractive metallurgy further west in the late fourth millennium BC.

This paper presents twelve new radiocarbon dates from copper mines at Monte Loreto in Liguria, northwest Italy, which indicate that extraction began around 3500 cal BC, making these the earliest copper mines to be discovered in Western Europe so far. The dates are placed in their regional context, with a discussion of results from Libiola and other sites associated with early copper mining.
