" It was one of the great fen sunsets, flaming across the sky from horizon to horizon, burning up the earth beneath it to nothingness. But it could not subdue the Cathedral. Isaac was looking straight up at the three great towers and the flaming clouds were streaming out from them like banners. Yet there was no wind, and no movement in the sky except just above the Rollo tower where two small white clouds were in gentle flight. They soared and sank again, infinitely graceful and lovely, the golden light touching their wings and breasts. Then they soared once more and were lost in the light. They were two white swans. "
