The first settlement occurred during the second millennium cal BCE, probably by continental Bronze Age communities. During the first centuries of occupation (ca. 2100–1400 cal BCE), local material culture is defined in terms of the Bell-Beaker/Dolmenic and First Naviform periods. The Pityusic Islands have no mineral resources for producing copper or bronze objects locally, so the presence of metal objects dated to these periods necessarily indicates exog- enous contact. Seven metal objects have been found in five archaeological sites located in both islands. Archaeometallurgical research conducted on these objects reveals the economic behaviour of these first settlers in acquiring these resources. In this respect, aspects of this behaviour, such as technological patterns and trade dynamics, are analysed. Keywords Bronze age . Pityusic Islands . Metal trade . Isolation . Island colonisation .
