Thaumaturgia Part 14

Eclipses furnished more frequent occasions for the exercise of their talent. From this worthy precedent of Judicial Astrology, others took the hint and invented new modes of divination, such as Geomancy, Chiromancy, Onomancy, and the like; till the world by degrees became so overrun with superst.i.tion, that the least trifle was converted into a presage or presentiment; and the more so when this kind of knowledge became the business of religion; and when the substance of divine wors.h.i.+p consisted in the ordinances of Augurs who, to make themselves necessary in the world, were obliged to keep up and quicken men's apprehensions of the wrath of G.o.d, took special care to cultivate comets, and bring it into a proverb, that "so many comets so many calamities." They knew, as Livy expresses it, that it was best to fish in troubled waters, where, speaking of a contagious distemper, which, from the country villages, spread over the city, occasioned by an extraordinary drought in the year of Rome 326, he observes how, at last, it infected the mind,[124] by the management of those who lived in the superst.i.tion of the people; so that nothing was to be seen or heard except some new fangled ceremony or other in every corner. "The devil,"

as Bayle says, "who had a hopeful game on't, and saw superst.i.tion the surest way to get himself wors.h.i.+pped under the name of the false G.o.ds, in a hundred various ways, all criminal and abominable in the sight of the sovereign Lord of heaven and earth, never failed, on the appearance of any rare meteor, or uncommon star, to exert his imposing arts, and make idolaters believe, they were the signs of divine wrath, and that they were all undone unless they appeased their G.o.ds by sacrifices of men and brute beasts."

Politicians have also lent a helping hand to give presages a reputation, as an excellent scheme, either to intimidate the people, or to raise their drooping spirits. Had the Roman soldiers been free thinkers, Drusus, the son of Tiberius, had not been so fortunate as to quell a desperate mutiny among the legions of Pannonia, who utterly refused to obey his commands; but an eclipse, which critically intervened, broke their refractory spirits to such a degree, that Drusus, who managed their panic fear with great dexterity and address, did what he liked with them.

An eclipse of the moon put the army of Alexander the Great into such a consternation, some days before the battle of Arbela, that the soldiers, under the impression that heaven was against them, were very reluctant to advance; and their devotion turning to downright disobedience, Alexander commanded the Egyptian astrologers, who were the deepest versed in the mystery of the stars, to give their opinions of this eclipse in the presence of all the officers of his army. Without giving themselves much trouble to explain the physical cause which it was their interest to conceal from the people, the wise men declared that the sun was on the side of the Grecians, and the moon for the Persians; and that this planet was never in an eclipse, but it threatened them with some mighty disaster: of this they quoted several ancient examples among the kings of Persia, who, after an eclipse, had always found their G.o.ds unpropitious in the day of battle. "Nothing," says Quintus Curtius,[125]

"is so effectual as superst.i.tion for keeping the vulgar under. Be they ever so unruly and inconstant, if once their minds are possessed with the vain visions of religion, they are all obedience to the soothsayer, whatever becomes of the general." The answer of the Egyptian astrologers being circulated among the soldiers, restored their confidence and their courage.

On another occasion Alexander, just before he pa.s.sed the river Granicus, observing the circ.u.mstance of time, which was the month Desius, reckoned unfortunate to the Macedonians from all antiquity, it made the soldiers melancholy; he immediately ordered this dangerous month to be called by the name of that which preceded it, well knowing what power and influence vain religious scruples have over little and ignorant minds. He sent private orders to Aristander his chief soothsayer, just offering up a sacrifice for a happy pa.s.sage, to write on the liver of the victim with a liquor prepared for that purpose, that the G.o.ds had "granted the victory to Alexander." The notice of this miracle filled the men with invincible ardour; and now they rent the air with acclamations, exclaiming that the day was their own, since the G.o.ds had vouchsafed them such plain demonstrations of their favour. The history, indeed, of this mighty conqueror, affords more such examples of artifice, though he always affected to conquer by mere dint of bravery.

But what is still more extraordinary, this very hero, who palmed so often such tricks upon others, was himself caught in his turn, as being well as exceedingly superst.i.tious by fits. We say nothing of Themistocles,[126] who, in the war between Xerxes and the Athenians, despairing to prevail upon his countrymen by force of reasoning to quit their city, and betake themselves to sea, set all the engines of religion to work; forged oracles, and procured the priests to circulate among the people, that Minerva had fled from Athens, and had taken the way which led to the port. Philip of Macedon, whose talent lay in conquering his enemies by good intelligence, purchased at any price, had as many oracles at command as he pleased; and hence Demosthenes justly suspecting too good an understanding between Philip and the Delphian priestess, rallied her with so much acrimony upon her partiality to that prince. It is equally obvious how the same reasons of state, which kept up the popular superst.i.tion for other prodigies, should take care to encourage it with regard to comets and other celestial appearances.

Panegyrists have also done their parts to promote the superst.i.tion of presages, as well as the flattering of poets and orators. When a hero is to be found and extolled, they exclaim, that _all nature adores him; that she exerts her utmost powers to serve him; that she mourns at his misfortunes, promises him long before hand to the world; and when the world, by its sins, is unworthy to possess him longer, heaven, which calls him home, hangs out new lights, etc._ With this hyperbole M.

Balzac regaled Cardinal Richelieu, adding, that _to form such a minister, universal nature was on the stretch; G.o.d gives him first by promise, and makes him the expectation of ages_. For this he was attacked by the critics, but he defended himself; alleging, that other panegyrics had gone some notes higher: he, for example, among the ancients, who said of certain great souls that _all the orders of heaven were called together to fancy a fine destiny for them_, and that ill.u.s.trious nation who wrote that _the eternal mind was wrapt in deep contemplation, and big with the vast design, when it conceived such a genius as Cardinal Hippolito d'Este_. Why could not this same writer have thought of one example more, such as that of the priest who told the Emperor Constantine that _divine Providence, not content with qualifying him for the empire of the world, had formed virtues in his soul, which should ent.i.tle him to reign in heaven with his only son_.

Thus have flatterers seized the most surprising natural effects to enhance their hero's glory, and make their court to great men. The poets of the time of Augustus vied with each other in persuading the world that the murder of Julius Caesar was the cause of all the prodigies that followed. Horace, for instance, in one of his odes, attempts to prove that the overflowings of rivers were reckoned among bad presages; and pretends that the Tiber had not committed all those ravages, but in complaisance to his wife Ilia, who was bent on the death of his kinsman Caesar; and that all the other calamities which subsequently afflicted or threatened the Roman empire, were the consequences of his a.s.sa.s.sination. If Virgil may be credited,[127] the sun was so troubled at the death of Caesar that it went into deep mourning, and so obscured his beams, that the world was alarmed lest it never should appear again. In the mean time, no sooner was the comet observed, which followed this murder, than another set of flatterers pretended that it was Caesar's soul received into the order of the G.o.ds; and they dedicated a temple[128]

to the comet, and set up the image of Caesar with a star on his forehead.

It appears from the sermons of the ancient fathers, that the Christians of that time believed they gave great relief to the moon in an eclipse, by raising hideous shouts to the skies, which they imagined recovered her out of her fainting fit, and without which she must inevitably have expired. St. Ambrose, the author of the 215th sermon _de tempore_, bound up with those of St. Austin, and St. Eloy, Bishop of Noyon, declaim particularly against this abuse. It appears also from the Homilies of St. Chrysostom, St. Basil, St. Austin, and others, that the Christians of their days drew several kinds of presages from persons sneezing at critical times; from meeting a cat, a dog, or an ill-looking (squinting) woman, a maiden, one blind of an eye, or a cripple; on being caught by the cloak on stepping out of a door, or from a sudden catch in one's joint or limb.

St. Eloy tells his people plainly, that whoever pays attention to what he meets at his first going out or coming in, or to any particular voice, or to the chirping of a bird, is so far a Pagan. Indeed, all these, and innumerable others of the same description of superst.i.tious among Christians, are remnants of ancient paganism; as they have been denounced by the censures of popes, provincial councils, synodical decrees, and other grave authorities. And, though there were not such a cloud of witnesses, there would be no difficulty in proving the disease of pagan origin. For, independent of those who preached the gospel of our Saviour, having never promulgated such notions, we learn from several ancient authorities, that the Gentiles had all these superst.i.tions in the highest regard. It was one general opinion among them, that the eclipses of the moon were the consequence of certain magic words by which sorcerers could wrench her from the skies, and drag her near enough the earth to cast a frothy spittle on their herbs--one of the princ.i.p.al ingredients in their incantations. To rescue the moon from the supposed torture she was in, and to frustrate the charm, it was necessary to prevent her from hearing the magic words, by drowning in noise and hideous outcries, for which purpose the people used to a.s.semble during an eclipse of the moon with _rough_ music, such as frying pans, brazen vessels, old tin kettles, etc. According to Pietro della Voile, the Persians keep up the same ridiculous ceremony to this day. It is likewise, according to Tavernier, observed in the kingdom of Tunquin, where they imagine the moon to be, at that time, struggling with a dragon. It is to the same source that we owe the imaginary raging heat of the dog-star--the pretended presages of several evils ascribed to eclipses, and all the allusions of astrology.

In a treatise written by Abogard, Bishop of Lyons, in 833, composed to undeceive a world of people, who were persuaded that there were enchanters who could command thunder, and hail, and tempest, to destroy the fruits of the earth; and that they drove a great trade by this mystery with the people of a certain country called Magonia, who came once a year, sailing in large fleets through the air, to freight with the blighted corn, for which they paid down ready money to the enchanters. So little was this matter doubted, that one day the bishop had enough to do to save three men and a woman from being stoned to death, the people insisting they had just fallen overboard from one of these aerial s.h.i.+ps.

We do not here examine whether, in those days, the people literally were more superst.i.tious and credulous than in the days of paganism. It is enough to say, that they were of very easy belief; and hence men began to write their histories in the style of romance, mixing up a thousand fables with the deeds of great men, such as Roland, nephew to Charlemagne; which so suited the taste of the age, that no book would afterwards go down in any other style--witness, for instance, the Manual of Devotions by James de Voragine, archbishop of Genoa, composed towards the latter end of the thirteenth century; and in which Melchior Ca.n.u.s, a learned Spanish bishop, is so scandalized in his eleventh book of Common Places. Another doctor of divinity,[129] speaking of the depraved state of the times, says, "It was the error, or rather folly, of some of the ancients, to think, that in writing the actions of ill.u.s.trious men, the style must sink, unless they mixed up with it the ornaments, for so they called them, of poetical fiction, or something of this sort; and, consequently, thus blended truth with fable." This being the prevailing fas.h.i.+on of the times, we are inclined to believe, that in the histories of the crusades, many apocryphal subjects are introduced, which ought, consequently, to be read _c.u.m grano salis_. This is decidedly the opinion of Pere Maimbourg,[130] who, after the relation of the battle of Iconium, won by Frederick of Barbarossa, 1190, says, "What was chiefly wonderful after this battle, was the conqueror's sustaining little or no loss, which most people ascribed to the particular protection of St.

Victor and St. George, names oftenest invoked in the Christian army, which many of them said they saw engaging at the head of the squadrons.

Whether in reality there might be something in it extraordinary, which has often happened, as the Scriptures inform us; or whether, by often hearing of celestial squadrons appearing at the battle of Antioch in the first crusade, warm imaginations possessed with the belief, and penetrated with these ideas, formed new apparitions of their own, but sure it is, that one Louie Helfenstein, a gentleman of reputation, and far from a visionary, affirmed to the emperor, on his oath, and on the vow of a pilgrim devoted to the holy sepulchre and the crusade, that _he often saw St. George charge at the head of the squadrons, and put the enemy to flight_; which was afterwards confirmed by the Turks themselves, owning that they saw some troops in white charge in the first ranks in the Christian army, though there were really none of that livery. No one, I know, is bound (continues P. Maimbourg) to believe visions of this kind, subject for the most part to notorious illusion: but I know too, that an historian is not of his own authority, to reject them, especially when supported by such remarkable testimony.

"And though he be at liberty to believe or not, yet he has no regret, by suppressing them, to deprive the reader of his liberty, when he meets with pa.s.sages of this kind, of judging as he thinks fit." This reflection (says Bayle) from so celebrated an historian, not suspected of favouring the Hugonot incredulity, is a strong presumption on my side.

The abuse of presentiments has been carried to the very Scriptures. We are told, that the manner of Tamerlane giving his blessing to his two sons, by bowing down the head of the elder, and chucking the youngest under the chin, was a presage of the elevation of the latter in prejudice to the former, was grounded on the 48th chapter of Genesis, where Jacob is represented laying his right hand on the head of the younger, forseeing by inspiration that he would be the greater of the two. Meanwhile there is a difference between the two benedictions. The Tartar, wholly dest.i.tute of the knowledge of future events, did not diversify the motion of his hands, on purpose to establish a presage; and G.o.d never vouchsafing this knowledge to infidels, did not guide his hands in a particular manner to form a presage of what should befal his children;--whereas Jacob, on the contrary, filled with the spirit of prophecy, whereby he saw the fortunes of his children, directed his words and actions according to this knowledge; by which means both became presages.

Presages, presentiments, and prodigies, might be multiplied ad infinitum. Whoever reads the Roman historians will be surprised at their number, and which frequently filled the people with the most dreadful apprehensions. It must be confessed, that some of these seem altogether supernatural; while much the greater part only consist of some of the uncommon productions of nature, which superst.i.tion always attributed to a superior cause, and represented as the prognostications of some impending misfortunes. Of this cla.s.s may be reckoned the appearance of two suns;[131] the nights illuminated by rays of light; the views of fighting armies; swords and spears darting through the air; showers of milk, of blood, of stones, of ashes, or of fire; and the birth of monsters, of children, or of beasts who had two heads; or of infants who had some feature resembling those of the brute creation. These were all dreadful prodigies which filled the people with inexpressible astonishment, and the whole Roman empire with an extreme perplexity; and whatever unhappy event followed, repentance was sure to be either caused or predicted by them.

[131] Nothing is more easy than to account for these productions, which have no relation to any events, no more than comets, that may happen to follow them. The appearance of two suns has frequently happened in England, as well as in other places, and is only caused by the clouds being placed in such a situation as to reflect the image of that luminary; nocturnal fires, inflamed spears, fighting armies, were no more than what we call aurora borealis, northern lights, or inflamed vapours floating in the air; showers of stones, of ashes, or of fire, were no other than the effects of the eruptions of some volcano at a considerable distance. Showers of milk were only caused by some quality in the air condensing and giving a whitish colour to the water, etc.

CHAPTER XVI.

PHENOMENA OF METEORS, OPTIC DELUSIONS, SPECTRA, ETC.

The meteors known to the ancients were called [Greek: Lampdes Pithoi]

Bolides, Faces, Globi, etc. from particular differences in their shape and appearance, and sometimes under the general term of comets. In the Philosophical Transactions, they are called, indiscriminately, fire-b.a.l.l.s, or fiery meteors; and names of similar import have been applied to them in the different languages of Europe. The most material circ.u.mstances observed of such meteors may be brought under the following heads: 1. Their general appearance. 2. Their path. 3. Their shape or figure. 4. Their light and colour. 5. Their height. 6. The noise with which they are accompanied. 7. Their fire. 8. Duration, 9.

Their velocity. Under these different heads meteors have been investigated by the scrutinizing of philosophy, and many superst.i.tious notions, long entertained concerning them, entirely exploded. Meteoric phenomena, it has been demonstrated, all proceed from one common cause--irregularity in the density of the atmosphere. When the atmospheric fluid is h.o.m.ogenous and of equal density, the rays of light pa.s.s without obstruction or alteration in their shape or direction; but when they enter from a rarer into a denser medium, they are refracted or bent out of their course; and this with greater or less effect according to the different degrees of density in the media, or the deviation of the ray from the perpendicular. If the second medium be very dense in proportion, the ray will be both refracted and reflected; and the object from which it proceeds, will a.s.sume a variety of grotesque and extraordinary shapes, and it will sometimes appear as in a reflection from a concave mirror, dilated in size, and changed in situation.

The following striking effects are known to proceed from this simple cause.

The first is the mirage, seen in the desert of Africa. M. Monge, a member of the National Inst.i.tute, accompanied the French army into Egypt. In the desert, between Alexandria and Cairo, the mirage of the blue sky was inverted, and so mingled with the sand below, as to impart to the desolate and arid wilderness an appearance of the most rich and beautiful country. They saw, in all directions, green islands, surrounded with extensive lakes of pure and transparent water. Nothing could be conceived more lovely and picturesque than this landscape. On the tranquil surface of the lakes, the trees and houses, with which the islands were covered, were strongly reflected with vivid hues, and the party hastened forward to enjoy the cool refreshments of shade and stream, which these populous villages preferred to them. When they arrived, the lake, on whose bosom they floated, the trees, among whose foliage they were embowered, and the people who stood on the sh.o.r.e inviting their approach, had all vanished, and nothing remained but an uniform and irksome desert of sand and sky, with a few naked huts and ragged shrubs. Had they not been undeceived by their nearer approach, there was not a man in the French army who would not have sworn, that the visionary trees and lakes had a real existence in the midst of the desert.

The same appearance precisely was observed by Dr. Clarke at Raschid, or Rosetta. The city seemed surrounded by a beautiful sheet of water, and so certain was his Greek interpreter, who was acquainted with the country, of this fact, that he was quite indignant at an Arab, who attempted to explain to him, that it was a mere optical delusion. At length, they reached Rosetta in about two hours, without meeting any water; and, on looking back on the sand they had just crossed, it seemed to them, as if they had just waded through a vast blue lake.

A similar deception takes place in northern climates. Cities, battlements, houses, and all the accompaniments of populous places, are seen in desolate regions, where life goes out, and where human foot has never trod. When approached they vanish, and nothing remains but a rugged rock, or a misshapen iceberg.

Captain Scoresby, in his voyage to the arctic regions, on the coast of East Greenland, constantly saw those visionary cities, and gives some highly curious plates of the appearances they presented. They resembled the real cities seen on the coast of Holland, where towers, and battlements, and spires, "bosomed high in tufted trees," rise on the level horizon, and are seen floating on the surface of the sea. Among the optic deceptions noticed by Captain Scoresby, was one of a very singular nature. His s.h.i.+p had been separated by the ice, from that of his father for some time; and he was looking for her every day, with great anxiety. At length, one evening, to his utter astonishment, he saw her suspended in the air in an inverted position, traced on the horizon in the clearest colours, and with the most distinct and perfect representation. He sailed in the direction in which he saw this visionary phenomenon, and actually found his father's vessel by its indication. He was divided from him by immense ma.s.ses of icebergs, and at such a distance that it was quite impossible to have seen the s.h.i.+p in her actual situation, or seen her at all, if her spectrum, or image, had not been thus raised several degrees above the horizon into the sky, by this most extraordinary refraction, in the same manner as the sun is often seen, after he is known to have set, and actually sunk far below the line of direct vision.

The _Fata Morgana_ are further ill.u.s.trations of this optic delusion.

This phenomenon is seen at the Pharo of Messina, in Sicily, under certain circ.u.mstances. The spectator must stand with his back to the east, on an elevated place behind the city, commanding a view of the bay, and having the mountains, like a wall, opposite to him, to darken the back ground of the picture; no wind must be abroad to ruffle the surface of the sea; and the waters must be pressed up by currents, as they sometimes are, to a considerable height in the middle of the strait, and present a slight convex surface. When all these circ.u.mstances occur, as soon as the sun rises over the heights of the Calabrian sh.o.r.e, and makes an angle of 45 with the horizon, all the objects on the sh.o.r.e at Reggio are transferred to the middle of the strait, and seen distinctly on the surface of the water, forming an immoveable landscape of rocks, trees, and houses, and a moveable one of men, horses, and cattle; these are formed into a thousand separate compartments, presenting most beautiful and ever varying pictures of animate and inanimate nature, on the swelling surface of the water, broken by the currents, present separate plates of convex mirrors to reflect them; they then as suddenly disappear, as the broad aquatic mirror of the current pa.s.ses on.

Sometimes the atmosphere is so dense that the objects are seen, like Captain Scoresby's s.h.i.+p, s.n.a.t.c.hed 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 mora.s.s, and the vapour generated in the ma.s.s, and broken by the mountains, continually represent the most fantastic objects; and often those on sh.o.r.e 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 sh.o.r.e, 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 a.s.sumed, 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 a.s.semble on the sh.o.r.e 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 sh.o.r.e, 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 pa.s.sed 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 att.i.tudes, 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 G.o.d 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 gla.s.s.

This const.i.tution 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 superst.i.tious. 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.

CHAPTER XVII.

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:--
