Pride of place in this review goes undoubtedly to Sally Humphreys’ monumental study of kinship in ancient Athens. A work in progress for four decades, it is finally published in two volumes of almost 1,500 pages. The book's coverage is vast: the first volume focuses on interactions among kinsfolk (legal, social, economic, and ritual), while the second volume explores the various Athenian corporate groups which employed kinship as their organizing principle (phratries, gene, tribes, and trittyes) and provides an exhaustive discussion of kinship networks attested across all Athenian demes. As a result of its size and encyclopaedic coverage, I suspect that most readers will approach this work in a piecemeal fashion, looking for a particular phenomenon or searching for a particular kinship network; the lack of a detailed introduction or conclusions – features that would have been essential in a work of this size and ambition – does not help in this respect. But this work needs to be assessed as a whole, for three main reasons. The first is that households were the main organizing units of Athenian society, while most Athenian groups were organized on a kinship principle. Their roles were crucial, and they need to complement the social models of Athenian society we employ, alongside class and status. The second reason is that Humphreys makes a very good job of exploring the various contradictory tendencies at work in how Athenian kinship operated: the interests of male heads; of wives, children, and relatives; of wider kinship networks; and of the political community. The third is the combination of literary, epigraphic, and material evidence of Athenian kinship, which reveals in often impressive ways the contradictions and gaps of our various sources: not only will this work be essential reading for those working on Athenian oratory, archaeology, or economy, but its accumulated detail offers the basis for writing a novel history of Athenian society. Of course, a work gestated for forty years will also show the unavoidable flaws of its piecemeal construction; but these are largely of secondary importance, compared to the value of the end product.
