The Light Princess by George MacDonald

The princess burst into a passion of tears, and fell on the floor. There she lay for an hour, and her tears never ceased. All the pent-up crying of her life was spent now. And a rain came on, such as had never been seen in that country. The sun shone all the time, and the great drops, which fell straight to the earth, shone likewise. The palace was in the heart of a rainbow. It was a rain of rubies, and sapphires, and emeralds, and topazes. The torrents poured from the mountains like molten gold; and if it had not been for its subterraneous outlet, the lake would have overflowed and inundated the country. It was full from shore to shore.

But the princess did not heed the lake. She lay on the floor and wept, and this rain within doors was far more wonderful than the rain out of doors.
