This work examines the post-palatial phase of Late Helladic IIIC middle. During this phase in Greek prehistory, Greece undergoes important changes that will transfer the palace administrative system of the Mycenaean era to that of the city-states of the early Greek period. At the time of its publication much of the material evidence known today was still unpublished and although the material examined provided a most thorough account of what was known at the time it was still limited as a result of the lack of publications or as often was the case the lack of LH IIIC, or so defined, deposits. This phase of the Bronze Age has been periodically examined either through the investigation of specific sites or in certain cases with the study of a particular type of material find such as pottery. What this publication aims to provide is a more synthetic study of the middle phase in its entirety within the regions of the central and southern Aegean. By examining the archaeological material from settlements and burials of the middle phase, together with their associated finds of pottery, terracotta figurines, jewellery and weapons, it is hoped that they will provide valuable insight into this phase and provide information concerning the new social and economic structures that arose in response to the loss of the Mycenaean administrative centres.
