The perils of darkness, as ambush of foes human and animal, concealer of pitfalls, misguider of footsteps, misdirector of aims, were more real than men can well imagine in an age of gaslight plus the policeman. The myth of Joshua commanding the sun to stand still; the cry of Ajax when darkness fell on the combat, ‘Grant me but to see!’ refer us to the region from which come all childish shudders at going into the dark. The limit of human courage is reached where its foe is beyond the reach of its force. Fighting in the dark may even be suicidal. A German fable of blindfold zeal—the awakened sleeper demolishing his furniture and knocking out his own teeth in the attempt to punish cats—has its tragical illustrations also. But none of these actual dangers have been of more real evil to man than the demonisation of them. This rendered his very skill a blunder, his energy weakness. If it was bad to retreat in the dusk from an innocent bush into an unrecognised well, it was worse to meet the ghost with rune or crucifix and find it an assassin. When man fights with his shadow, he instantly makes it the demon he fears; ghoul-like it preys upon his paralysed strength, vampyre-like it sucks his blood, and he is consigned disarmed to the evil that is no shadow. The Scottish Sinclair marching through Norway, in the 16th century, owes his monument at Wiblungen rather to the magpie believed to precede him as a spy, with night and day upon its wings, than to his own prowess or power.

In a sense all demons, whatever their shapes, are the ancient brood of night. Mental darkness, even more moral darkness within, supply the phantasmagoria in which unknown things shape themselves as demons. Esau is already reconciled, but guilty Jacob must still wrestle with him as a phantom of Fear till daybreak. A work has already been written on ‘The Night-side of Nature,’ but it would require many volumes to tell the story of what monsters have been conjured out of the kind protecting darkness. How great is the darkness which man makes for himself out of the imagination which should be his light and vision! Much of the so-called ‘religion’ of our time is but elaborate demoniculture and artificial preservation of mental Walpurgis-nights. Nott (Night) says the Edda rides first on her horse called Hrimfaxi (frost-maned), which every morning as he ends his course bedews the earth with the foam that falls from his bit. Though the horse of Day—Skinfaxi, or Shining-mane—follows hard after her, yet the foam is by no means drunk up by his fires. Foam of the old phantasms still lingers in our mediæval liturgies, and even falls afresh where the daylight is shut out that altar-candles may burn, or for other dark seances are prepared the conditions necessary for whatsoever loves not the light.

What we call the Dark Ages were indeed spiritually a perpetual seance with lights lowered. Nay, human superstition was able to turn the very moon and stars into mere bluish night-tapers, giving just light enough to make the darkness visible in fantastic shapes fluttering around the Prince of Darkness,—or Non-existence in Chief! How much of the theosophic speculation of our time is the mere artificial conservation of that darkness? How much that still flits bat-winged from universities, will, in the future, be read with the same wonder as that with which even the more respectable bats can now read account of the midnight brood which now for the most part sleep tranquilly in such books as Burton’s ‘Anatomy of Melancholy’? ‘There are,’ he says, ‘certain spirits which Miraldus calls Ambulones, that walk about midnight on great heaths and desert places, which (saith Lavater) draw men out of their way, and lead them all night by a byway, or quite bar them of their way. These have several names in several places. We commonly call them Pucks. In the deserts of Lop, in Asia, such illusions of walking spirits are often perceived, as you may read in M. Paulus, the Venetian, his travels. If one lose his company by chance, these devils will call him by his name, and counterfeit voices of his companions to seduce him. Lavater and Cicogna have a variety of examples of spirits and walking devils in this kind. Sometimes they sit by the wayside to give men falls, and make their horses stumble and start as they ride (according to the narration of that holy man Ketellus in Nubrigensis, that had an especial grace to see devils); and if a man curse and spur his horse for stumbling, they do heartily rejoice at it.’

While observing a spirited and imaginative picture by Macallum of the Siege of Jerusalem, it much interested me to observe the greater or less ease with which other visitors discovered the portents in the air which, following the narrative of Josephus, the artist had vaguely portrayed. The chariots and horsemen said to have been seen before that event were here faintly blent with indefinite outlines of clouds; and while some of the artist’s friends saw them with a distinctness greater, perhaps, than that with which they impressed the eye of the artist himself, others could hardly be made to see anything except shapeless vapour, though of course they all agreed that they were there and remarkably fine.

It would seem that thus, in a London studio, there were present all the mental pigments for frescoing the air and sky with those visions of aërial armies or huntsmen which have become so normal in history as to be, in a subjective sense, natural. In the year 1763, an author, styling himself Theophilus Insulanus, published at Edinburgh a book on Second-Sight, in which he related more than a hundred instances of the power he believed to exist of seeing events before they had occurred, and whilst, of course, they did not exist. It is not difficult in reading them to see that they are all substantially one and the same story, and that the sight in operation was indeed second; for man or woman, at once imaginative and illiterate, have a second and supernumerary pair of eyes inherited from the traditional superstitions and ghost stories which fill all the air they breathe from the cradle to the grave. While the mind is in this condition, that same nature whose apparitions and illusions originally evoked and fostered the glamoury, still moves on with her minglings of light and shade, cloud and mirage, giving no word of explanation. There are never wanting the shadowy forms without that cast their shuttles to the dark idols of the mental cave, together weaving subtle spells round the half-waking mind.

In the year 1743 all the North of England and Scotland was in alarm on account of some spectres which were seen on the mountain of Souter Fell in Cumberland. The mountain is about half-a-mile high. On a summer evening a farmer and his servant, looking from Wilton Hall, half a mile off, saw the figures of a man and a dog pursuing some horses along the mountain-side, which is very steep; and on the following morning they repaired to the place, expecting to find dead bodies, but finding none. About one year later a troop of horsemen were seen riding along the same mountain-side by one of the same persons, the servant, who then called others who also saw the aërial troopers. After a year had elapsed the above vision was attested before a magistrate by two of those who saw it. The event occurred on the eve of the Rebellion, when horsemen were exercising, and when also the popular mind along the Border may be supposed to have been in a highly excited condition.

What was seen on this strongly-authenticated occasion? Was anything seen? None can tell. It is open to us to believe that there may have been some play of mirage. As there are purely aërial echoes, so are there aërial reflectors for the eye. On the other hand, the vision so nearly resembles the spectral processions which have passed through the mythology of the world, that we can never be sure that it was not the troop of King Arthur, emerging from Avallon to announce the approaching strife. A few fleecy, strangely-shaped clouds, chasing each other along the hillside in the evening’s dusk would have amply sufficed to create the latter vision, and the danger of the time would easily have supplied all the Second-Sight required to reveal it to considerable numbers. In questions of this kind a very small circumstance—a phrase, a name, perhaps—may turn the balance of probabilities. Thus it may be noted that, in the instance just related, the vision was seen on the steep side of Souter Fell. Fell means a hill or a steep rock, as in Drachenfels. But as to Souter, although, as Mr. Robert Ferguson says, the word may originally have meant sheep,[7] it is found in Scotland used as ‘shoemaker’ in connection with the fabulous giants of that region. Sir Thomas Urquhart, in the seventeenth century, relates it as the tradition of the two promontories of Cromarty, called ‘Soutars,’ that they were the work-stools of two giants who supplied their comrades with shoes and buskins. Possessing but one set of implements, they used to fling these to each other across the opening of the firth, where the promontories are only two miles apart. In process of time the name Soutar, shoemaker, was bequeathed by the craftsmen to their stools. It is not improbable that the name gradually connected itself with other places bearing traditions connecting them with the fabulous race, and that in this way the Souter Fell, from meaning in early times much the same as Giants’ Hill, preserved even in 1743–44 enough of the earlier uncanny associations to awaken the awe of Borderers in a time of rebellion. The vision may therefore have been seen by light which had journeyed all the way from the mythologic heavens of ancient India: substantially subjective—such stuff as dreams and dreamers are made of—no doubt there were outer clouds, shapes and afterglows enough, even in the absence of any fata morgana to supply canvas and pigment to the cunning artist that hides in the eye.

In an old tale, the often-slain Vampyre-bat only requests, with pathos, that his body may be laid where no sunlight, but only the moonlight, will fall on it—only that! But it is under the moonshine that it always gains new life. No demon requires absolute darkness, but half-darkness, in which to live: enough light to disclose a Somewhat, but not enough to define and reveal its nature, is just what has been required for the bat-eyes of fable and phantasy, which can make vampyre of a sparrow or giant out of a windmill.

Glamour! A marvellous history has this word of the artists and poets,—sometimes meaning the charm with which the eye invests any object; or, in Wordsworth’s phrase, ‘the light that never was on land or sea.’ But no artist or poet ever rose to the full height of the simple term itself, which well illustrates Emerson’s saying, ‘Words are fossil poetry.’ Professor Cowell of Cambridge says: ‘Glám, or in the nominative Glámr, is also a poetical name for the Moon. It does not actually occur in the ancient literature, but it is given in the glossary in the Prose Edda in the list of the very old words for the Moon.’ Vigfusson in his dictionary says, ‘The word is interesting on account of its identity with Scot. Glamour, which shows that the tale of Glam was common to Scotland and Iceland, and this much older than Grettir (in the year 1014).’ The Ghost or Goblin Glam seems evidently to have arisen from a personification of the delusive and treacherous effects of moonlight on the benighted traveller,
