Low down in the west the new moon, leaning on its side, rocked and turned softly in its sleep; and there, facing the earth through the cleared night, the blue moon hung like a burning grape against the sky. Like the heart of a sapphire laid open, the air flushed and purpled to a deeper shade. The wind drew in its breath close and hushed, till not a leaf quaked in the boughs; and the sea that lay out west gathered its waves together softly to its heart, and let the heave of its tide fall wholly to slumber. Round-eyed, the stars looked at themselves in the charmed water, while in a luminous azure flood the light of the blue moon flowed abroad.
Under the light of many tapers within drawn curtains of tapestry, and feasting her eyes upon the happiness of Hands, the Princess felt the change that had entranced the outer world. “I feel,” she said, “I do not know how—as if the palace were standing siege. Come out where we can breathe the fresh air!”
The light of the tapers grew ghostly and dim, as, parting the thick hangings of the window, they stepped into the night.
“The blue moon!” cried Nillywill to her heart; “oh, Hands, it is the blue moon!”
All the world seemed carved out of blue stone; trees with stems dark-veined as marble rose up to give rest to boughs which drooped the altered hues of their foliage like the feathers of peacocks at roost. Jewel within jewel they burned through every shade from blue to onyx. The white blossoms of a cherry-tree had become changed into turquoise, and the tossing spray of a fountain as it drifted and swung was like a column of blue fire. Where a long inlet of sea reached in and touched the feet of the hanging gardens the stars showed like glow-worms, emerald in a floor of amethyst.
There was no motion abroad, nor sound: even the voice of the nightingale was stilled, because the passion of his desire had become visible before his eyes.
“Once in a blue moon!” said Nilly-will, waiting for her dream to become altogether true. “Let us go now,” she said, “where I can put away my crown! To-night has brought you to me, and the blue moon has come for us: let us go!”
“Where shall we go?” asked Hands.
“As far as we can,” cried Nillywill. “Suppose to the blue moon! To-night it seems as if one might tread on water or air. Yonder across the sea, with the stars for stepping-stones, we might get to the blue moon as it sets into the waves.”
But as they went through the deep alleys of the garden that led down to the shore they came to a sight more wonderful than anything they had yet seen.
