The remarkable jade adze, generally known as the “Kunz adze,” was found in Oaxaca, Mexico, brought to the United States about 1890, and is now in the American Museum of Natural History, New York. Of a light greenish-gray hue, with a slight tinge of blue, this jade artefact is 272 mm. long (10¹³/₁₆ inches), 153 mm. wide (6 inches) and 118 mm. thick (4⅝ inches); its weight is 229.3 Troy ounces, nearly sixteen pounds avoirdupois. Rudely, but not unskilfully, carved upon its face is a grotesque human figure. Four small, shallow depressions, one under each eye and one near each hand, may have served to hold in place small gold films, but no trace of gold decoration is now extant. In its mechanical execution this adze offers evidence of considerable skill on the part of the Aztec lapidary, the polish equalling that of modern workers. In the fact that a large piece, which must apparently have weighed at least two pounds, has evidently been cut out of this implement by some one of its Indian owners, we can see a proof of the talismanic power ascribed to jadeite in Aztec times, for there can be little doubt that nothing less than a belief in the great virtue of jadeite coupled with the rarity of the material could have induced the mutilation of what must have been regarded in its time as a remarkable work of art.377

The source of the prehistoric jade (nephrite and jadeite) found in Europe, and also of that worked into ornaments by the Indians before the Spanish Conquest of America, was long the subject of contention among mineralogists and archæologists. In Germany this question was denominated the Nephritfrage, and the most notable contribution to the discussion was the great scientific and scholarly work issued by Heinrich Fischer.378 His conclusion was that as there was no evidence of the existence of these minerals outside of a few localities in Asia, the European and American supply must have been brought to these parts of the world from Asia, and that hence the presence of these jade artefacts in America clearly pointed to commercial intercourse at an early period between the American continent and Asia, and might be regarded as offering a strong argument in favor of an Asiatic origin for an American civilization. According to this theory the prehistoric jade objects found in Europe must have had a similar source, and would constitute a proof of the existence of traffic with remote points in Asia at a date long previous to that commonly accepted.

This view was strongly opposed by Prof. A. B. Meyer, of Dresden, and recent discoveries have effectively disproved the theory in the case of Europe at least, for nephrite has been found there in situ in several places. The largest mass of this material that has been taken from a European deposit is that found by the writer at Jordansmühl in Silesia, in April, 1899, and which weighed 4704 pounds.379 The origin of American jade in the forms of nephrite and jadeite has not yet been definitely determined, but we have every reason to suppose that deposits of these minerals will eventually be discovered in various parts of the American continent, as they have already been in Europe. Indeed, the existence of nephrite in Alaska is already well attested.

The peculiar and characteristic qualities of these substances have made them favorite materials for ornamental objects from the earliest ages down to our own day, and in almost all parts of the world. A most important element contributing to the popularity of jade has been its supposed possession of wonderful talismanic and therapeutic virtues, and while the Western world has not the same belief in these matters as the Eastern world, a more or less definite appreciation of what jade still signifies for many in the Orient, continues to exercise an influence over both Americans and Europeans, making objects of nephrite or jadeite highly prized everywhere at the present time.

The term chalchihuitl was indifferently applied by the ancient Mexicans to a number of green or greenish-white stones; quetzal chalchihuitl, which was regarded as the most precious variety, may perhaps have more exclusively denoted jadeite. This is somewhat indefinitely described by Sahagun as being “white, with much transparency, and with a slight greenish tinge, something like jasper.” Of eight ornamental objects of green stone examined some years ago by the writer, four were of jadeite, one of serpentine, another of green quartz, and the remaining two of a mixture of white feldspar and green hornblende. An inferior kind of chalchihuitl, said by Sahagun to have come from quarries in the vicinity of Tecalco, appears to have been identical with the so-called “Mexican onyx” which is found in veins in that place and is an aragonite stalagmite. This material, from which figures, ornaments and beads were made by the ancient Mexicans, is to-day greatly valued as an ornamental stone.

The greater number of ancient Mexican jadeite beads appear to have been rounded pebbles of this material, assorted as to size and drilled for use in making necklaces. Other green stones used at this time in Mexico were green jasper, green plasma, serpentine and also the “Tecalco onyx” or “marble” above mentioned. In many cases these substances are of such rich green that they might easily be mistaken for jadeite by those who lacked the tests or the experience at the command of modern mineralogists. Should jadeite ever be found in situ in Mexico, it seems probable that the discovery will be made in the State of Oaxaca, whence came the finest ancient specimens, including the splendid votive adze. Moreover, one of the few materials by which jadeite can be worked is furnished by the streams of this region, whence have been taken several rolled pebbles which the writer has identified as yellow and blue corundum, the quality being equal to that of specimens from Ceylon.380

Gesner describes one of the lip ornaments worn by the aborigines of South America in the following words:381

A green stone or gem which the inhabitants of the West Indies use. They pierce their lips and insert this stone so that the thicker part adheres to the hole and the rest protrudes. We might call these ornaments oripenduli [mouth-pendants]. This stone was given me by a learned Piedmontese, Johannes Ferrerius, and he wrote of it as follows: “I send a cylindrical green stone, as long as a man’s middle finger, and having at one extremity two ridges. It is stated that the Brazilians of high rank wore these, from their youth, in their pierced lips; one or more being worn according to the dignity of the wearer. While eating, or whenever they so wish for any other reason, these ornaments are removed from the lips.”

Similar ornaments, made of a green quartz and of beryl, are in the Kunz collection in the Field Museum of Chicago.

The reason for these strange mutilations, which often cause serious discomfort to those who practice them, is not at all easy to determine. Some have conjectured that by the insertion of bright, colored objects in the ears, nose and lips, members of the same tribe were enabled to recognize each other at a distance; each tribe having selected a particular color. However, although certain local preferences are shown in the matter of color or material, there is no hard and fast rule in this matter, and frequently neighboring tribes will employ stones or shells of the same or similar hue and appearance. Others find in this custom a religious significance and suppose that the mutilation represents a form of sacrifice to the spirits, good or bad, who must be rendered favorable to man by some act on his part showing his unconditional submission to them. Originating in this way the idea of adornment was a secondary impulse. It is a fact that ancient peoples regarded the wearing of ear-rings as a badge of slavery, and, according to a Rabbinical legend, Eve’s ears were pierced as a punishment for her disobedience, when she was driven from the Garden of Eden.

A curious theory was advanced by Knopf.382 He calls attention to the habit children have of thrusting small bright objects into their noses and ears, and suggests that this indicates a natural propensity which, coupled with the early-developed love of adornment, induced primitive man to affix ornamental objects on or in the nose, ear, or mouth. There may be more in this than we are willing to admit, but on the whole it seems most probable that ceremonial and religious considerations gave rise to the custom.

One of the largest masses of sculptured Chinese jade is in the collection of T. B. Walker, Esq., of Minneapolis. This shows a jade mountain, with groups of figures artistically placed at its base, and winding pathways up to its summit. On the face of the rock is inscribed in beautiful Chinese characters the Epidendron Pavilion Essay of Wang Hi-che, a masterpiece of Chinese calligraphy.

An enormous mass of New Zealand jade (punamu, “green stone”) weighing 7000 pounds, found in South Island in 1902, is to be seen in the Museum of Natural History, New York; it was secured by the writer and was donated to the Museum by the late J. Pierpont Morgan. This is the largest mass of jade known, or of which we have any record. On it is placed a remarkable and, in its own peculiar way, an artistic decoration, serving as a type of old Maori life, and at the same time designating the geographic source of the jade in a striking and unmistakable manner calculated to appeal to the least intelligent visitor. This is a statue of a Maori warrior of the old days, executing a war dance, characteristics of which were a distortion of the features and a thrusting out of the tongue intended to express defiance and contempt of the enemy; the time or cadence of the dance was marked by slapping the thigh with the flat of the left hand. This figure was executed from life by Sigurd Neandross; indeed it was actually cast from the model, so that there can be no doubt as to its fidelity.

Rock-crystal is included among the various objects used as fetiches by the Cherokee Indians. This stone is believed to have great power to give aid in hunting and also in divining. One owner of such a crystal kept his magic stone wrapped up in buckskin and hid it in a sacred cave; at stated intervals he would take it out of its repository and “feed” it by rubbing over it the blood of a deer. This goes to prove that the stone, as a fetich, was considered to be a living entity and as such to require nourishment.383

Precious stones have been everywhere regarded as especially appropriate offerings at the shrine of a divinity, for the worshipper naturally thought that what was most valuable and beautiful in his eyes must also be most pleasing to the divinity he worshipped. However, we rarely find the usage which was remarked by Francisco Lopez de Gomara among the Indians of New Granada about the time of the Spanish Conquest.384 These natives “burned gold and emeralds” before the images of the sun and moon, which were regarded as the highest divinities. Certainly to use precious stones for a “burnt offering” was an original and curious idea, although we have abundant proof that pearls were offered in this way by the mound-builders of the Mississippi Valley. In this case great quantities of pearls were burned at the obsequies of the chiefs of the tribes, or at those of any one belonging to the family of a chief.

In ancient Mexico the lapidaries adored the four following divinities as their tutelary gods: Chiconaui Itzcuintli (“nine dogs”), Naualpilli (“noble necromancer”), Macuilcalli (“five horses”), and Cintectl (“the god of harvest”). A festival was celebrated in honor of the three last-named divinities when the zodiacal sign called chiconaui itzcuintli was in the ascendant. A feminine divinity represented this sign and to her was attributed the invention of the garments and the ornaments worn by women. The four gods of the lapidaries were looked upon as the discoverers and teachers of the art of cutting precious stones and of piercing and polishing them, as well as of the making of labrets and earflaps of obsidian, rock-crystal, or amber. They also were the inventors of necklaces and bracelets.385

The stones worn by Chinese mandarins as a designation of their rank were undoubtedly determined originally by religious or ceremonial considerations. They are as follows; it will be noticed that red stones are given the preference:

The knowledge of classical mythology was so slight among the ecclesiastics of the Middle Ages that some very queer attributions of the subjects engraved on Greek and Roman gems were made during this period. A reliquary containing a tooth of the Apostle Peter, preserved in the Cathedral of Troyes, was set with antique gems which had been plundered by French and Venetian crusaders from the treasure-house of the Greek Emperor in Constantinople, when that city was sacked in 1204 during the Fourth Crusade. Among these gems was one representing Leda and the Swan—certainly a curious subject for the adornment of a Christian reliquary. Another Greek or Roman gem, long preserved in a church, was furnished by its Christian owners with an inscription indicating that the figure engraved upon it was that of St. Michael, while in reality it was a representation of the god Mercury. Still another gem was provided with an inscription signifying that the subject was the temptation of Mother Eve in the Garden of Eden, but the Greek gem engraver’s intent had been to carve the figures of Zeus and Athena, standing before an olive tree, a design which appears on some Athenian coins; at the feet of the divinities appears a serpent. In a similar way the grain-measure crowning the head of Jupiter-Serapis led to the attribution of a gem so engraved to the patriarch Joseph.386

An engraved amethyst bearing the figure of a little Cupid is said to have been worn in a ring by St. Valentine. While this may be somewhat doubtful, it is by no means impossible, for many pagan gems were worn by pious Christians, who reconciled their consciences to the use of these beautiful but scarcely religious ornaments by giving to the pagan symbols a Christian meaning. Certainly, in view of the time-honored customs connected with St. Valentine’s Day, there seems something peculiarly appropriate in the design of the ring supposed to have been worn by St. Valentine.

That precious stones had sense and feeling was quite generally believed in medieval times, and a legend told of St. Martial illustrates this idea. The gloves worn by this saint were studded with precious stones, and when on a certain occasion a sacrilegious act was committed in his presence, the gems, horrified at the sight, sprang out of their settings and fell to the ground before the eyes of the onlookers.

The famous “Sacro Catino” preserved in Genoa was long believed to be made of a single immense emerald, but careful investigation proved that it was of no more valuable material than green glass. A legend still current in the early part of the sixteenth century represented this cup, or dish, as having been used by Christ at the Last Supper, and stated that it was one of the utensils which King Herod ordered to be brought from Galilee to Jerusalem for the celebration of the paschal feast; but his purpose having been changed by Divine Providence, he made other use of it.387

A queer story has been told regarding the Genoese emerald. At one time when the government was hard pressed for money, the Sacro Catino was offered to a rich Jew of Metz as pledge for a loan of 100,000 crowns. He was loath to take it, as he probably recognized its spurious character, and when his Christian clients forced him to accept it under threats of dire vengeance in case of refusal, he protested that they were taking a base advantage of the unpopularity of his faith, since they could not find a Christian who would make the loan. However, when some years later the Genoese were ready to redeem this precious relic, they were much puzzled to learn that a half-dozen different persons claimed to have it in their possession, the fact being that the Jew had fabricated a number of copies which he had succeeded in pawning for large sums, assuring the lender in each case that the redemption of the pledge was certain.

Among the celebrated emeralds noted by George Agricola388 (1490-1555) was a large one preserved in a monastery near Lyons, France. This is also mentioned by Gesner, who states that it was shaped as a dish, or shallow cup, and was held to be the Holy Grail, like its rival at Genoa.389 Another of Agricola’s emeralds was somewhat smaller, but nevertheless measured nine inches in diameter and was in the chapel of St. Wenceslaus, at Prague; this may have been a chrysoprase, as at the present day many fine specimens of this stone can be seen in St. Wenceslaus, where the walls are inlaid with the golden green gem-stone. Still another, larger than the last named, was set in the gold monstrance in Magdeburg, and was believed to have been the handle of Emperor Otho I’s knife, since it was perforated. Possibly, however, the emerald, if genuine, was an Oriental stone, for it was customary to pierce rubies, sapphires, emeralds, etc., in the East so as to string them for necklaces or attach them as pendants to a jewel.

In the convent-church of St. Stephan, in Persian Armenia, erected about the middle of the seventeenth century, it is related by the French traveller Tavernier that there was preserved a cross said to be made out of the basin in which Christ washed the feet of the Apostles. Set in this cross was a white stone, and the priests asserted that when the cross was laid upon the body of one seriously ill, this stone would turn black if he were about to die, but would regain its white hue after his death.390

No jewelled sacred image has been the object of greater reverence than has been accorded to the rude little wooden carving popularly known as the “Sacro Bambino” or “Sacred Baby,” in the old church of Ara Coeli in Rome. This figure was carved, in 1847, by a monk, out of a piece of olive-wood from one of the ancient trees growing on the Mount of Olives near Jerusalem. The carving was executed in the Holy Land and was sent thence to Italy, and although the ship bearing it was shipwrecked, this precious freight was miraculously preserved and is supposed to have been conveyed to its destination in some mysterious way. The reverence of the thousands of pilgrims who in the course of time have gazed with veneration upon this quaint and curious work of art, has found expression in the bestowal of a wealth of gems and jewels, including necklaces, brooches, rings, etc., with which the silken dress of the image is studded. A crown of gold adorned with precious stones rests upon the head of the olive-wood figure, which is jealously guarded by the priests and only shown to the faithful as a particular favor, except on the occasion of certain religious festivals.

One of the most renowned emeralds in the world surmounted the elaborately jewelled imperial crown that was placed upon the head of the venerated image of the Virgen del Sagrario in the Cathedral of Toledo. This emerald, of a rich green color, was cut as a perfect sphere and measured about 40 millimetres, or 1½ inches, in diameter. The crown itself was the work of the Toledan goldsmith, Don Diego Alejo de Montoya, who began his task in 1574 and devoted twelve years to its completion. It is described as being of almost pure gold and executed in the Renaissance style. Curiously chased in arabesque designs and enamelled in various colors, the framework of the crown served as a magnificent background for the gems constituting its adornment, which comprised rubies, emeralds, and Oriental pearls; a row of angels and cherubs sustained the arches which bore at their summit the allegorical figures of Faith, Hope, and Charity; upon that representing Faith rested the splendid emerald. This precious ornament was still preserved in the Cathedral in 1865, but was so carelessly guarded that it was stolen in 1869.391

If we are to believe the following anecdote, the emerald disappeared at an earlier date: It is said that in 1809, during the French occupation of Spain, Marshal Junot visited this cathedral, and the emerald was pointed out to him as one of the chief glories of the shrine. As soon as the marshal’s covetous glance rested upon the gem, he plucked it from its setting, remarking, coolly, to the astonished and horrified bystanders, “This belongs to me.” Then, smiling and bowing, he left the cathedral with the emerald safely ensconced in his waistcoat pocket. Later, it was replaced by an imitation in glass.

The famous collection of jewels gathered together in the treasury of the Santa Casa, at Loreto, Italy, was plundered during the French occupation in 1797, and all trace of most of the magnificent ornaments has been lost. These represented the gifts of many crowned heads and titled personages; among the former was the unfortunate Henrietta Maria, wife of Charles I, who donated a golden heart-shaped jewel with the words “Jesus Maria” incrusted in diamonds. This jewel is described as being “as big as both a man’s hands, opened onto two leaves, on one of which was the figure of the Blessed Virgin and on the other a portrait of the queen herself.”392 Of the many rich vestments for decorating the statue of the Virgin in the sanctuary, the most splendid was the gift of the Infanta Isabel of Flanders, and was valued at 40,000 crowns. In a seventeenth-century account by an English traveller it is thus described:393

Its set thick with six rows of diamonds downe before, to the number of three thousand, and its all wrought over with a kinde of embroidery of little pearle set thick everywhere within the flowers with great round pearle, to the number twenty thousand pearles in all.

The same writer tells us the niche in which the statue was placed was bordered with a row of precious stones of great number, size, and value, the colors being so varied that this bordering formed “a rich Iris of several colors.” There is also said to have been a great pearl, set in gold, and engraved with the image of the Virgin and Child.394 It seems probable that this was a jewel made of a baroque pearl, or pearls, completed by enamel-work so as to represent the sacred figures.

The pectoral cross worn in solemn processions by the prior of the monastery of San Lorenzo del Escorial was adorned with eight perfect emeralds, five diamonds, and five pearls. From it hung a splendid pear-shaped pearl, the gift of Philip II in 1595, and one of the finest of those acquired by this monarch. In 1740 the cross was valued at 50,000 crowns, Philip’s great pearl not being included in this valuation.395

The monastery of Streoneshalh, later Whitby Abbey, was founded about 656 A.D. by Oswy, King of Northumbria, in fulfilment of a vow made before his victory over the pagan king Penda, at the battle of Winwidfield, fought in November, 654. St. Hilda was made abbess of this monastery, and Oswy’s daughter Aelfleda took the veil and eventually, in 680, succeeded Hilda as abbess; she died in 713.396 Tradition relates that at this early date crosses and rosaries were made for the inmates of the monastery from the jet found in the neighborhood. The “Whitby jet,” so popular and fashionable in the eighteenth century, was largely derived from the same source, and since then has had several revivals, until replaced by black-stained chalcedony, the so-called onyx, and, later still, by steel carved with glass and glass itself.

In the sixteenth century jet was popularly called “black amber,” and Cardano states that in his time beads of this material were made up into rosaries. He also says that curious figures made of jet were brought from Spain to Italy.397

Many are unaware of the fact that a number of ornamental objects made of nephrite and jadeite—unquestionably of European origin—are to be seen in the quiet little town of Perugia. These objects, collected principally in central and southern Italy, constitute the Belucci Collection, in that city. This collection also contains other specimens of worked jadeite, which must have been brought to Europe at the time of the Spanish conquest of Mexico and Peru. A very interesting example shows us the utilization of a pagan celt to form a Christian emblem. By the removal of a rectangular piece from each of the four corners of the jadeite celt, a perfect cross has been made, the back and front of which still offer the original polish given to the material centuries ago by the native American worker. The superstitious belief propagated in Europe by the returning Spanish sailors, very probably an invention of their own to enhance the value of their jade and jadeite, that these minerals were worn by the natives as a cure for diseases of the kidneys, whence the name lapis nephriticus, rendered the material exceptionally precious in the eyes of many, and quite possibly it may have been thought that, by transforming this object into the sacred form of the cross, a talisman would be produced that would not only effect the cure of a special disease, but would also by its superior virtue guard the wearer from harm and danger of all kinds. Here may also be seen some celts of European jade sewed up in little bags to be worn on the loins.

Certain curious amulets called magatama (crooked jewels) have been found in Japanese graves of the iron age;398 they are formed of various materials, among others of steatite, jasper, carnelian, agate, rock crystal, chrysoprase and nephrite (jade). In the shell heaps of a period preceding the iron age, the magatama are frequently made of horn, or of boar’s or wolf’s teeth, and their peculiar form, which is variously explained as a symbol, may have been conditioned by the shape of the materials originally used. The magatama were evidently regarded as amulets. “They are generally perforated at the thick end, and were worn on a string, together with beads and bugles of the same material.” These peculiar ornaments were used to adorn the statues of the gods and were also employed as imperial insignia and distinctive marks of high rank. At the present day they are numbered among the three emblems of sovereignty in Japan.

A green and a red magatama are combined in the national emblem of Korea and a similar figure is used in China to symbolize the union of the masculine and feminine principles (Yang and Yin) in nature. Dr. Baelz believes that the swastika emblem, encountered in so many different parts of the world, belongs to the same order of ideas.

The Bghai tribes of Burma have many superstitions in regard to stones, such as garnets, rock-crystal, chalcedony, carnelian, agate, onyx and others of less value, their repute not depending entirely or principally upon their quality as gem-stones. In almost every household is installed a stone fetish, and blood offerings are on occasion made to this. A question as to the reason for this offering elicited the following reply: “If we do not give it blood to eat it will eat us.” A common belief was that spirits good or bad dwelt in the stones, and in case a great misfortune befell a family, this was sometimes laid to the charge of such a spirit. The father of a family having died, his widow commanded her son to throw away their magic stone. This he did, but the spirit was not to be denied, for shortly afterward this very stone was found to have returned to its accustomed place, and had even brought two companion stones with it!399

Ruy Gonzalez de Clavijo, who travelled in the East during the years 1403-1406, gives a description of a slab of stone bearing the outlines of a “natural picture,” and placed in the church of St. Sophia, in Constantinople:400

In the wall, on the left-hand side, there is a very large white slab, on which, among many other figures, was drawn, very naturally, without any human artifice of sculpture or painting, the most sacred and blessed Virgin Mary, with our Lord Jesus Christ in her most holy arms, with his most glorious forerunner, St. John the Baptist, on one side. These images, as I said before, are not drawn or painted with any color, or inlaid, but the stone itself gave birth to this picture, with its veins, which may be clearly seen; and they say that when this stone was cut, to be placed in this most holy place, the workman saw these most wonderful and fortunate images on it, and, as this church was the most important one in the city, that stone was deposited in it. The said images appear as if they were in the clouds of heaven, and as if there was a thin veil before them.

Many other examples of these “natural gems” are noted by early writers. Among them was an agate gem in the treasury of the Basilica of St. Mark, in Venice. Upon this gem appeared the head of a king, adorned with a diadem, the whole design being figured naturally by the veining of the agate, and not owing anything to artifice. In the same city, upon a column in the church of San Georgio Maggiore, could be seen the likeness of Our Lord, hanging from the Cross.401

Such stones, with peculiar markings indicating the form of human heads and figures, were regarded as the work of higher powers.

Another remarkable example is described by Kircher as follows:402

In Rome, in the Chapel of the Sacred Virgin, near the organ to the right hand of those who enter the Church of St. Peter, an image may be seen in which the Blessed Virgin of Loreto is so artistically depicted by Nature that it appears to be the work of an artist’s hand. She is attired in a triple garment, divided by a zone, and holds in her arms the child, who is distinguished by a crown, as is the mother. Around may be seen the figures of angels.

The red spots upon the bloodstone were said in Christian legend to represent the blood of Christ. This idea has been beautifully utilized in some gems cut from this stone, whereon the thorn-crowned head of Christ is so placed that the red spots of the bloodstone figure the drops of blood trickling down the hair and face of the Saviour. Such a gem might well be looked upon as a Christian amulet and one that could be reverently worn by any believer.

The ignorance in the Middle Ages of the art of gem-engraving often induced the belief that engraved stones were the work of nature. A striking instance of this was the celebrated stone over the figure of the Mother of Jesus, on the tomb of St. Elizabeth of Marburg. On this gem appeared two heads touching each other, and it was, according to tradition, not a work of art, but a freak of the sculptress Nature. An oft-repeated legend tells us that a former Elector of Mainz offered the whole district of Amöneberg for this costly stone, which robber hands removed at Cassel. It is in reality a fine onyx engraved with the heads of Castor and Pollux.403

We might be disposed to regard rather sceptically the tales regarding wonderful stones bearing the image of Christ, or that of the Virgin Mary, and we may be inclined to believe that the old accounts are exaggerated or distorted by the pious imaginations of the writers. Nevertheless, in our own time we have a well-attested case of the discovery of such a stone.

In 1880, while visiting the village of Oberammergau, Bavaria, to witness the Passion Play, Mrs. Eugenia Jones-Bacon, of Atlanta, Georgia, found on Mount Kopfel, which overlooks the village, a small stone composed of chert and limestone, and having on its surface excrescences so disposed that, when the stone was held at a certain angle, the shadows cast by them formed a striking likeness of the head of Christ as depicted in Christian art. This peculiar freak specimen has been carefully examined by experts and has been pronounced to be entirely a work of nature. The mineralogist is not disposed to see here anything more than coincidence, and yet the most sceptical cannot fail to be impressed by the fact that such a stone was found at the time and place of the Passion Play. As Max Müller said, in commenting on this strange discovery: “The chapter of accidents is much larger than we imagine,” and the present writer feels disposed to add that it is remarkable how often we find what we are looking for, especially if we are only looking or thinking of one object or subject.

The religious symbolism of the diamond was a favorite theme with the thirteenth century “lapidaria,” or rhymed treatises on precious stones. Just as it could only be discovered by night—an old fancy—so was the Incarnation a hidden mystery; it gave forth a great light, just as Jesus illumined the depths of Hades when he descended thither; it was unconquerably hard, and who can resist the might of God?404

The mediæval Italians who were fond of seeking some hidden and significant meaning in the names of precious stones, in the case of the diamond (diamante), read the phrase amante di Dio, or “lover of God.”405 This was a reason for regarding the brilliant gem as a sacred stone and one especially suitable for religious use.

The Rosicrucians, who sought to combine pagan with Christian types and figures, saw in the amethyst and the amethystine color a symbol of the divine male sacrifice, since the stone and the color were typical of love, truth, passion, suffering, and hope. The love of Christ led him to make the supreme sacrifice and suffer the agony of the Cross, and the Crucifixion was followed by the Resurrection, whence came the hope of mankind to enjoy eternal happiness in heaven.

The chiastolite, or macle, shows the representation of a cross on its surface, this effect being produced by the regular arrangement of carbonaceous impurities along the axes of the crystal. The name signifies a marking resembling the Greek letter Χ (chi). This marking is often very striking in appearance, and the crystal was naturally regarded as having a mystical and religious significance. It was said to stanch the flow of blood from any part of the body if worn so as to touch the skin, and it was also believed to increase the secretion of milk. All kinds of fevers were cured by this mineral if it were worn suspended from the neck, and the divine symbol it bore served to drive away evil spirits from the neighborhood of the wearer.

This very interesting mineral occurs very frequently in mica schists. When found, it appears about the thickness of a small finger, tapering slightly at each edge. If broken near one end, it often shows a white cross with a veined outline of black, making a distinct cross with black markings. The crystals frequently measure from two to four inches in length, and are found in Massachusetts, California, and other places. If small segments are broken off, it will be found that the black outline will become stronger, and the white less marked, until finally a black cross will appear, with white markings. The white material is the result of two white wedges pushed point onward until the ends meet, the narrow end of one wedge being crossed by the broad end of the second wedge, and the black filling in the balance of the square. No two of these square crosses can thus ever be exactly alike, and, when polished, the crystals naturally form an interesting stone that was known as lapis crucifer, or cross-stone by the ancients.

In some epitaphs the hope of the resurrection finds expression in likening the body enclosed in its narrow coffin to a precious jewel in its casket. The following lines from a tombstone erected in 1655 to the memory of Mary Courtney, at Fowell, Cornwall, England, give a good example of this class of inscription:406

In a churchyard at Prittlewell, Essex, England, a rather whimsical treatment of the same idea is offered by some verses engraved on the stone marking the graves of two wives of a certain Freeborne, the first of whom died in 1641 and the second in 1658. The bereaved husband seems to have been perfectly willing to await the Day of Judgment for the return of his lost spouses:407
