An intensive archaeological survey covering the entire extent of the island of Antikythera has recently revealed a sequence of prehistoric activity spanning the later Neolithic to Late Bronze Age, with cultural affiliations that variously link its prehistoric communities with their neighbours to the north, south and east. Here we present and discuss the results of a programme of both macroscopic and petrographic study of the prehistoric ceramics from Antikythera that defines a varied group of fabrics and explores their implications with regard to regional potting traditions, onisland production versus imports, and changing patterns of human activity on the island through time. Greece, and we are especially grateful to Jonathan Tomlinson for his assistance. The petrographic analysis discussed here was undertaken at the Fitch Laboratory, British School of Athens with the help of a British Academy small grant (SG-45163) and we would like to thank both of these institutions for their support. The co-director and synergast for the Antikythera Survey Project was Aris Tsaravopoulos, and we could not have undertaken this research without his generous assistance and guidance. We are also extremely grateful to Cyprian Broodbank, co-director of the Kythera Island Project, who provided a wide range of discussion, advice and support from the burnish on exterior?
