In this volume deriving from the first international conference of the Danish National Research Foundation's Centre for Black Sea Studies thirteen contributions by scholars from Russia, Ukraine, Romania, USA, Canada, Belgium and Denmark review and discuss the elements on which the chronology used in Black Sea archaeology and history in the period c. 400-100 BC is built up. The subjects include: amphora and amphora stamp chronologies, coin chronology, the Athenian pottery, epigraphic evidence, and a number of case studie.
