Seven warriors yonder, doughty chiefs of might, Into the crimsoned concave of a shield Have shed a bull's blood, and, with hands immersed Into the gore of sacrifice, have sworn By Ares, lord of fight, and by thy name, Blood-lapping Terror, Let our oath be heard- Either to raze the walls, make void the hold Of Cadmus-strive his children as they may- Or, dying here, to make the foemen's land With blood Impasted.
"Suppliant Maidens and Other Plays"
