And then, in the blowing clouds, she saw a band of faint iridescence colouring in faint colours a portion of the hill. And forgetting, startled, she looked for the hovering colour and saw a rainbow forming itself. In one place it gleamed fiercely, and, her heart anguished with hope, she sought the shadow of iris where the bow should be. Steadily the colour gathered, mysteriously, from nowhere, it took presence upon itself, there was a faint, vast rainbow. The arc bended and strengthened itself till it arched indomitable, making great architecture of light and colour and the space of heaven, its pedestals luminous in the corruption of new houses on the low hill, its arch the top of heaven.
And the rainbow stood on the earth. She knew that the sordid people who crept hard-scaled and separate on the face of the world’s corruption were living still, that the rainbow was arched in their blood and would quiver to life in their spirit, that they would cast off their horny covering of disintegration, that new, clean, naked bodies would issue to a new germination, to a new growth, rising to the light and the wind and the clean rain of heaven. She saw in the rainbow the earth’s new architecture, the old, brittle corruption of houses and factories swept away, the world built up in a living fabric of Truth, fitting to the over-arching heaven.
