At some uncertain date, probably within the decade 420 to 410 BCE, a son was born to an Athenian not so far known to fame, Charidemos 49 from Oion. The purpose of this chapter is to trace, from the two surviving law-court speeches Isaeus 11 and [Demosthenes] 43, the known activity of that son, Theopompos 54, in order to illustrate what the theme of this volume, kerdos, could mean in practice. Inevitably, it is derivative from the presentation of the family’s affairs given in Athenian Propertied Families (at 2921, pp.71-89 of the 1971 edition: at Bouselos 1 from Oion in the forthcoming new edition), but differs therefrom in that it focuses first and foremost on Theopompos himself, and does so because his personality and his strategies can to some degree be discerned. Much of what follows here hangs on family relationships. They are mostly not in dispute, but they are complex, so that readers new to the intricacies of Athenian prosopography will probably find it helpful to be guided visually by the family tree presented in Figure 14.1. Both there and in the text (as will be the case in APF2) the identification-numbers given to each individual (e.g., ‘Theopompos 54’) are those assigned in Lexicon of Greek Personal Names (LGPN) II. Male relatives identifiable but not named are cited as M1, M2, etc., female relatives likewise as F1, F2, etc. Relatives whose gender is unstated are identified as P1, P2, etc. Adoptions are signalled by arrowed lines. For detailed discussion about dates and relationships the reader is referred back to the sections of the entry in APF 1 or APF 2: section numbers will not change in APF 2.
