(Εὐξενίδαι), a noble family among the Aeginetans, celebrated by Pindar in his ode (Nem. vii.) in honour of one of its members, Sogenes, who was victorious in the boys' pentathlon in the 54th Nemead accordingg to Hermann's emendation of the Scholia), that is, in B. C. 462/1. The poet also mentions the victor's father, Thearion, with whom he seems to have been intimate. The ode contains some considerable difficulties, and has been very differently explained by Böckh, Dissen, and Hermann. (Pindar, l.c.; Schol., and Böckh and Dissen's notes; Hermann, de Sogenis Aeginetae Victoria quinquertii Dissertatio, Lips. 1822, Opuscula, vol. iii. p. 22.)
