The clouds hung like dark, blowing tapestries in the gaps of the hills.

the sky here's very strange. I often have the sensation when I look at it that it's a solid thing up there, protecting us from what's behind . . . [from] nothing, I suppose. Just darkness. Absolute night.

It was a stern night landscape. The sound of the freezing of snow over the land seemed to roar deep into the earth. There was no moon. The stars, almost too many of them to be true, came forward so brightly that it was as if they were falling with the swiftness of the void. As the stars came nearer, the sky retreated deeper and deeper into the night clolour. The layers of the Border Range, indistinguishable one from another, cast their heaviness at the skirt of the starry sky in a blackness grave and somber enough to communicate their mass. The whole of the night scene came together in a clear, tranquil harmony.

The offing was barred by a black bank of clouds, and the tranquil water-way leading to the uttermost ends of the earth flowed somber under an overcast sky — seemed to lead into the heart of an immense darkness.

Light still lingered in the sky; the hills, that had been dissolved in its splendour, like floating shapes of light themselves, grew dark again.

Darkness:

I had a dream, which was not all a dream.
The bright sun was extinguish'd, and the stars
Did wander darkling in the eternal space,
Rayless, and pathless, and the icy earth
Swung blind and blackening in the moonless air;
Morn came and went — and came, and brought no day,
And men forgot their passions in the dread
Of this their desolation; and all hearts
Were chill'd into a selfish prayer for light:
And they did live by watchfires — and the thrones,
The palaces of crowned kings — the huts,
The habitations of all things which dwell,
Were burnt for beacons; cities were consum'd,
And men were gather'd round their blazing homes
To look once more into each other's face;
Happy were those who dwelt within the eye
Of the volcanos, and their mountain-torch:
A fearful hope was all the world contain'd;
Forests were set on fire — but hour by hour
They fell and faded — and the crackling trunks
Extinguish'd with a crash — and all was black.
The brows of men by the despairing light
Wore an unearthly aspect, as by fits
The flashes fell upon them; some lay down
And hid their eyes and wept; and some did rest
Their chins upon their clenched hands, and smil'd;
And others hurried to and fro, and fed
Their funeral piles with fuel, and look'd up
With mad disquietude on the dull sky,
The pall of a past world; and then again
With curses cast them down upon the dust,
And gnash'd their teeth and howl'd: the wild birds shriek'd
And, terrified, did flutter on the ground,
And flap their useless wings; the wildest brutes
Came tame and tremulous; and vipers crawl'd
And twin'd themselves among the multitude,
Hissing, but stingless — they were slain for food.
And War, which for a moment was no more,
Did glut himself again: a meal was bought
With blood, and each sate sullenly apart
Gorging himself in gloom: no love was left;
All earth was but one thought — and that was death
Immediate and inglorious; and the pang
Of famine fed upon all entrails — men
Died, and their bones were tombless as th

"You know," said Port, and his voice sounded unreal, as voices are likely to do after a long pause in an utterly silent spot, "the sky here's very strange. I often have the sensation when I look at it that it's a solid thing up there, protecting us from what's behind."

Kit shuddered slightly as she said: "From behind?"
"Yes."
"But what is behind?" Her voice was very small.
"Nothing, I suppose. Just darkness. Absolute night."

..upon the frightening gray sky one can see a black mountain, completely black even with black houses, and all of a sudden a fire-red house appears, a violet path with snowflakes and on the path a black chain of people like crows.

Beyond the castle walls, the city lay in almost total darkness. Above, the moon was pallid and misted. It was a brooding, darkling night. And, it seemed to him, doom walked the heavens.

The sky? Dark as the inside of a priest’s heart, isn’t it?

He lay on his back in his blankets and looked our where the quartermoon lay cocked over the heel of the mountains. In the false blue dawn the Pleiades seemed to be rising up into the darkness above the world and dragging all the stars away, the great diamond of Orion and Cepella and the signature of Cassiopeia all rising up through the phosphorous dark like a sea-net. He lay a long time listening to the others breathing in their sleep while he contemplated the wildness about him, the wildness within.

The sky grew darker, painted blue on blue, one stroke at a time, into deeper and deeper shades of night.

The moods of the dark night skies are variously represented like soft black velvet, like the shining black of a scarab beetle, like the patina-ed surface of Indian-inked paper, soft blotting-paper soaked in dark blue ink for forty days, like a black cat's fur shining in moonlight...

The moon is darkened in the sky
As if grief 's shade were passing by;
