A sunset of copper and gold had just broken down and gone to pieces in the west, and grey colours were crawling over everything in earth and heaven; also a wind was growing, a wind that laid a cold finger upon flesh and spirit. The bushes at the back of my garden began to whisper like conspirators; and then to wave like wild hands in signal. I was trying to read by the last light that died on the lawn a long poem of the decadent period, a poem about the old gods of Babylon and Egypt, about their blazing and obscene temples, their cruel and colossal faces.

I read this poem because I had to review it for the Daily News; still it was genuine poetry of its kind. It really gave out an atmosphere, a fragrant and suffocating smoke that seemed really to come from the Bondage of Egypt or the Burden of Tyre There is not much in common (thank God) between my garden with the grey-green English sky-line beyond it, and these mad visions of painted palaces huge, headless idols and monstrous solitudes of red or golden sand. Nevertheless (as I confessed to myself) I can fancy in such a stormy twilight some such smell of death and fear. The ruined sunset really looks like one of their ruined temples: a shattered heap of gold and green marble. A black flapping thing detaches itself from one of the sombre trees and flutters to another. I know not if it is owl or flittermouse; I could fancy it was a black cherub, an infernal cherub of darkness, not with the wings of a bird and the head of a baby, but with the head of a goblin and the wings of a bat. I think, if there were light enough, I could sit here and write some very creditable creepy tale, about how I went up the crooked road beyond the church and met Something—say a dog, a dog with one eye. Then I should meet a horse, perhaps, a horse without a rider, the horse also would have one eye. Then the inhuman silence would be broken; I should meet a man (need I say, a one-eyed man?) who would ask me the way to my own house. Or perhaps tell me that it was burnt to the ground. I could tell a very cosy little tale along some such lines. Or I might dream of climbing for ever the tall dark trees above me. They are so tall that I feel as if I should find at their tops the nests of the angels; but in this mood they would be dark and dreadful angels; angels of death.

Only, you see, this mood is all bosh. I do not believe in it in the least. That one-eyed universe, with its one-eyed men and beasts, was only created with one universal wink. At the top of the tragic trees I should not find the Angel's Nest. I should only find the Mare's Nest; the dreamy and divine nest is not there. In the Mare's Nest I shall discover that dim, enormous opalescent egg from which is hatched the Nightmare. For there is nothing so delightful as a nightmare—when you know it is a nightmare.

That is the essential. That is the stern condition laid upon all artists touching this luxury of fear. The terror must be fundamentally frivolous. Sanity may play with insanity; but insanity must not be allowed to play with sanity. Let such poets as the one I was reading in the garden, by all means, be free to imagine what outrageous deities and violent landscapes they like. By all means let them wander freely amid their opium pinnacles and perspectives. But these huge gods, these high cities, are toys; they must never for an instant be allowed to be anything else. Man, a gigantic child, must play with Babylon and Nineveh, with Isis and with Ashtaroth. By all means let him dream of the Bondage of Egypt, so long as he is free from it. By all means let him take up the Burden of Tyre, so long as he can take it lightly. But the old gods must be his dolls, not his idols. His central sanctities, his true possessions, should be Christian and simple. And just as a child would cherish most a wooden horse or a sword that is a mere cross of wood, so man, the great child, must cherish most the old plain things of poetry and piety; that horse of wood that was the epic end of Ilium, or that cross of wood that redeemed and conquered the world.

In one of Stevenson's letters there is a characteristically humorous remark about the appalling impression produced on him in childhood by the beasts with many eyes in the Book of Revelations: “If that was heaven, what in the name of Davy Jones was hell like?” Now in sober truth there is a magnificent idea in these monsters of the Apocalypse. It is, I suppose, the idea that beings really more beautiful or more universal than we are might appear to us frightful and even confused. Especially they might seem to have senses at once more multiplex and more staring; an idea very imaginatively seized in the multitude of eyes. I like those monsters beneath the throne very much. But I like them beneath the throne. It is when one of them goes wandering in deserts and finds a throne for himself that evil faiths begin, and there is (literally) the devil to pay—to pay in dancing girls or human sacrifice. As long as those misshapen elemental powers are around the throne, remember that the thing that they worship is the likeness of the appearance of a man.

That is, I fancy, the true doctrine on the subject of Tales of Terror and such things, which unless a man of letters do well and truly believe, without doubt he will end by blowing his brains out or by writing badly. Man, the central pillar of the world must be upright and straight; around him all the trees and beasts and elements and devils may crook and curl like smoke if they choose. All really imaginative literature is only the contrast between the weird curves of Nature and the straightness of the soul. Man may behold what ugliness he likes if he is sure that he will not worship it; but there are some so weak that they will worship a thing only because it is ugly. These must be chained to the beautiful. It is not always wrong even to go, like Dante, to the brink of the lowest promontory and look down at hell. It is when you look up at hell that a serious miscalculation has probably been made.

Therefore I see no wrong in riding with the Nightmare to-night; she whinnies to me from the rocking tree-tops and the roaring wind; I will catch her and ride her through the awful air. Woods and weeds are alike tugging at the roots in the rising tempest, as if all wished to fly with us over the moon, like that wild amorous cow whose child was the Moon-Calf. We will rise to that mad infinite where there is neither up nor down, the high topsy-turveydom of the heavens. I will answer the call of chaos and old night. I will ride on the Nightmare; but she shall not ride on me.
