οὕνεκεν οἰκτείρειν οἶδε μόνη πολίων
Fr. 51 Harder (= 51 Pf.) Σ L R M S.OC 258
Only one line of this aition survives, praising Athens for her mercy. It is said to have come from the end of book 2.
οἰκτείρω: feel pity for, have pity upon
since it is the only one of cities which knows how to pity . . .
