Thaumaturgia; Or, Elucidations of the Marvellous

by Oxonian

Sometimes the atmosphere is so dense that the objects are seen, like Captain Scoresby's ship, snatched up into the regions of the air, thirty or forty feet above the level of the sea; and in cloudy weather, nearer to the surface, bordered with vivid prismatic colours. Sometimes colonades of temples and churches, with cross-crowned spires, are all represented as floating on the sea, and by a sudden change of representation, the pillars are curved into arcades, and the crosses are bent into crescents, and all the edifices of the floating city undergo the most extraordinary and fantastic mutations. All these images are so distinct, and produce objects seemingly as palpable as they are visible, as sensible to touch as to sight, that the people of the country are firmly persuaded of their reality. They consider the edifices as the enchanted palaces of the fairy Morgana, and the moving objects as living things which inhabit them. Whenever the optic phenomenon occurs, they meet together in crowds, with an intense curiosity, mixed with awe and apprehension, which is not removed by an acquaintance with those natural causes, by which Mr. Swinburn and other foreign travellers, who have witnessed the scene, are able to account for it.

The lakes of Ireland are equally susceptible of producing those vivid delusions, and the imagination of the people, as lively as that of the Sicilians, clothes them with an equal reality. There is scarcely a loch in that country, in which the remains of cities have not been at various times discovered; and many men have been met with who would solemnly swear they saw, and who no doubt did see, representations of them in certain states of the atmosphere. The most celebrated is that which occurs on the lake of Killarney. This romantic sheet of water is bounded on one side by a semi-circle of rugged mountains, and on the other by a flat morass, and the vapour generated in the mass, and broken by the mountains, continually represent the most fantastic objects; and often those on shore are transferred to the water, like the Fata Morgana.

Many of the rocks are distinguished for their marked and lengthened echoes, and the structure, which in acoustics reflects sounds to the ear, from a point from whence they did not come, reflects images on the eye, from a place very different from where the objects stood which produced them. Frequently men riding along shore, are seen as if they were moving across the lake, and this has given rise to the story of O'Donougho. This celebrated chieftain was, according to the tradition of the country, endued with the gift of magic; and, on one occasion, his lady requested him to change his shape, that she might see a proof of it. He complied, on condition that she would not be terrified, as such an effect on her must prove fatal to him. Her mind failed her, however, in the experiment, and at the sight of some horrible figure he assumed, she shrieked, and he disappeared through the window of his castle, which overhung the lake. From that time he continues an enchanted being, condemned to ride a horse, shod with silver, over the surface of the lake, till his horse's shoes are worn out. On every May morning he is visible, and crowds assemble on the shore to see him. Many affirm they have seen him; and one person relates many particulars of his apparition, that the deception must have proceeded from some real object, a man riding along shore, and transferred to the middle of the water, by the optic delusion of the Fata Morgana.

But perhaps the most wonderful, and apparently preternatural effect arising from this cause, is the spectre of the Hartz Mountains in Hanover. There is one particular hill, called the Brocken, in which he appears, terrifying the credulous, and gratifying the curious to a very high degree. The most distinct and interesting account is given by Mr. Hawe, who himself was a witness to it. He had climbed to the top of the mountain thirty times, and had been disappointed, but he persevered, and was at length highly gratified. The sun rose about four o'clock in a serene sky, free from clouds, and its rays passed without obstruction, over another mountain, called the Heinschoe. About a quarter past five he looked round to see if the sky was clear, and if there was any chance of his witnessing what he so ardently wished, when suddenly he saw the Achtermanshoe, a human figure of monstrous size turned towards him, and glaring at him. While gazing on this gigantic spectre with wonder mixed with an irrepressible feeling of awe and apprehension, a sudden gust of wind nearly carried off his own hat, and he clapped his hand to his head to detain it, when to his great delight the colossal spectre did the same. He then changed his body into a variety of attitudes, all which the figure exactly imitated, but at length suddenly vanished without any apparent cause, and again as suddenly appeared. He called the landlord of the inn, who had accompanied him, to stand beside him, and in a little time two correspondent figures, of dilated size, appeared on the opposite mountain. They saluted them in various ways by different movements of their bodies, all which the giants returned with perfect politeness, and then vanished. A traveller now joined Mr. Hawe and the innkeeper, and they kept steadily looking for their aerial friends, when they suddenly appeared again three in number, who all performed exactly the same movements as their correspondent spectators. Having continued thus for some time, appearing and disappearing alternately, sometimes faintly, and sometimes more distinct, they at length faded away not again to return. They proved, however, that the preternatural spectre, which had so long filled the country with awe and terror, was no unreal being, still less an existence whose appearance suspended the ordinary laws of God and Nature; that, on the contrary, it was the simple production of a common cause, exhibited in an unusual manner, but as regular an effect, and as easy to be accounted for, as the reflection of a face in a looking glass.

This constitution of the atmosphere, and its capability of dilating objects, and altering their position by reflection and refraction, will easily account for many phenomena which have been considered miraculous and preternatural in early ages, by the ignorant; and in our own, by the weak and superstitious. Such was probably the origin of the crosses seen by Constantine and Constantius in the first ages of Christianity, and such was that of the cross which appeared in the sky in France, to which so many bore attestation. A large cross of wood, painted red, had been erected beside the church, as a part of the ceremony they were performing. In the winter, when the air is most frequently condensed by cold, and its different strata of various degrees of tenacity, on a clear evening after rain, when particles of humidity, still floating in the air gives it greater power of reflection and refraction, when the sun was setting, and his horizontal beams found most favourable to produce meteoric phenomena, the spectrum of this wooden cross was cast on the concave surface of some atmospheric mirror, and so reflected back to the eyes of the spectators from an opposite place, retaining exactly the same shape and proportions, but dilated in size, and changed in position; and it was moreover tinged with red, the very colour of the object of which it was the reflected image. This delusive appearance continued till the sun was so far sunk below the horizon, as to afford no more light to illumine the object, and the image ceased when the rays were no longer distinctly reflected.

ELUCIDATION OF SOME ANCIENT PRODIGIES.

Many of the prodigies recorded by the ancients, admit of a natural explanation; and an attentive examination will show that a small number of causes, which may be discerned and developed, will serve for the explanation of nearly the whole of them. There are two reasons for our believing accounts of prodigies:—

1. The number and agreement of these accounts, and the confidence to which the observers and witnesses are entitled.

2. The possibility of dissipating what is wonderful, by ascertaining any one of the principal causes which might have given to a natural fact a tinge of the marvellous.
