recreant

[I]n the Choephoroe of Aeschylus Orestes pursues the same idea saying that unless he avenges his father, a stern duty which has devolved upon him, he will be punished in turn by the avengers of his father's wrongs. It may be remarked that in Maina to-day no recourse must be had to law for such cases, nor must the injured person satisfy himself by calling upon the aid of the police. To do this were incredibly base, the subterfuge of a recreant and a craven.
