Those belonging to the same clan [genos]. For the citizens of Athens used to be divided into parts, and the largest parts were called tribes [phylai], and each tribe was in turn divided into three, of which each part was named a riding [trittys] and a phratry. Each of the phratries was in turn divided into thirty clans, from which the priesthoods appropriate to each were filled by lot. And "clansmen" [were] those from the same and first clan of the thirty clans; [they were those] whom Philochorus says were previously called homogalaktes ["drinkers of the same milk"].[1] Isaeus, however, names the clansmen simply as those related to one another by blood.[2]
