Christy Constantakopoulou examines the history of the Aegean islands and changing concepts of insularity, with particular emphasis on the fifth century BC. Islands are a prominent feature of the Aegean landscape, and this inevitably created a variety of different (and sometimes contradictory) perceptions of insularity in classical Greek thought. Geographic analysis of insularity emphasizes the interplay between island isolation and island interaction, but the predominance of islands in the Aegean sea made island isolation almost impossible. Rather, island connectivity was an important feature of the history of the Aegean and was expressed on many levels. Constantakopoulou investigates island interaction in two prominent areas, religion and imperial politics, examining both the religious networks located on islands in the ancient Greek world and the impact of imperial politics on the Aegean islands during the fifth century.
