They stood in the church speaking with him a few minutes, then went out to the Paradiso.

A storm was coming up from the east, and round the angle of the building they could just see that the mountains in that direction were obliterated and mists fast filling the plain. Standing up against these mists, as if to impede their progress, was the lower end of a rainbow, set straight and solid on the green like a jewelled column. The cloud advanced and pushed the column before them.

“It is like the pillar of light leading the Israelites,” Isabel said.

The cloud unrolled itself above, and down through the rainbow ran a crinkling line of white fire.

“How plainly lightning asserts its own force!” Mr. Vane remarked. “Seeing it for the first time, without knowing what it was, one would know at once that it is an irresistible power. What an experience it would be to stand just near enough to a passing flash to perhaps hear it hiss through the air, to be between it and its thunder, and yet not so near nor so in its track as to be smitten!”

Little by little the sun was vanquished, and the rainbow grew dim, faltered, blushed along the line of the advancing shadows, and disappeared. There was an odd murmur growing up, fine and pervading—the sound of rain in the plain below. All the tiny noises of each falling drop joined in a multitude, countless nothings making themselves heard in pauses of the thunder. It was to solid sound as fine carving is to plain wood, as embroidery is to a fine web—a continued succession of millions of infinitesimal watery strokes separated by millions of infinitesimal silences.

The others went into the house at the first drop that splashed on the Paradiso, but the Signora went back to the portico and seated herself under its shelter. Behind her the court of the church looked weird and strange. The pillars of the porticos appeared to move as the lightnings came and went, the statues and busts behind them seemed to lean forward and retreat, and the one window in the church front looked blue, as if there were light inside it.

She took herself out of the draught, and went to lean on the wall between the doors. In front of her the grand stairs went down to the central court, and the gardens shone green and wet through the colonnades at either side. On a level with her, across the space, stretched the Paradiso, and under the portico that supported it a large, arched door led from the court out on to a beautiful loggia. Two or three monks, who had been standing in this loggia watching the storm, were driven in by the rain, and in a minute the whole place seemed to be deserted. The rain and the lightning had it to themselves and were washing and purifying all “so as by fire.”

This one visible witness felt her soul expand as she gazed. If only she also might be purified and enlightened in that time and place! If the littlenesses of life might be washed away from her, and only the realities remain!

“Come, Holy Spirit!” she said, and blessed herself.
