Fragoulaki has done an exhaustive and thorough study of the terms of xyngeneia (shared descent) in the narrative of Thucydides. She examines the phenomenon of kinship in cities, communities, and ethnic groups as portrayed in Thucydides and attempts to shed new light on his historical interpretations through this lens. Her work provides a useful reference tool for people studying the issues of kinship in Thucydides and the Peloponnesian War. This book is well worth reading for those interested in the Peloponnesian War.
