Obvious choices for the east window: two bloody bargains on which a civilization claims to be based. The bargain, Rivers thought, looking at Abraham and Isaac. The one on which all patriarchal societies are founded. If you, who are young and strong, will obey me, who am old and weak, even to the extent of being prepared to sacrifice your life, then in the course of time you will peacefully inherit, and be able to exact the same obedience from your sons. Only we're breaking the bargain, Rivers thought. All over northern France, at this very moment, in trenches and dugouts and flooded shell-holes, the inheritors were dying, not one by one, while old men, and women of all ages, gathered together and sang hymns.
