Chap. 11.—Amber: The Many Falsehoods That Have Been Told About It.

Next in rank among the objects of luxury, we have amber; [“Succinum.” It is of vegetable origin, and, according to Göppert, was originally the viscous resin of a tree named by him Pinites succinifer.] an article which, for the present, however, is in request among women [It is used by men, more particularly, at the present day, as a mouthpiece for pipes.] only. All these three last-mentioned substances hold the same rank, no doubt, as precious stones; the two former for certain fair reasons; crystal, because it is adapted for taking cool drinks, and murrhine vessels, for taking drinks that are either hot or cold. But as for amber, luxury has not been able, as yet, to devise any justification for the use of it. This is a subject which affords us an excellent opportunity of exposing some of the frivolities and falsehoods of the Greeks; and I beg that my readers will only have patience with me while I do so, it being really worth while, for our own practical improvement, to become acquainted with the marvellous stories which they have promulgated respecting amber.

After Phaëthon had been struck by lightning, his sisters, they tell us, became changed into poplars, [As to the vegetable origin of amber, there is no doubt that the ancients were right.] which every year shed their tears upon the banks of the Eridanus, a river known to us as the “Padus.” To these tears was given the name of “electrum,” [Most probably from ἥλιος, the “sun.” Phaëthon was fabled to have been the son of Apollo. See the story in Ovid’s Met. B. ii. l. 340, et seq.] from the circumstance that the Sun was usually called “elector.” Such is the story, at all events, that is told by many of the poets, the first of whom were, in my opinion, Æschylus, Philoxenus, Euripides, Satyrus, and Nicander; and the falsity of which is abundantly proved upon the testimony of Italy itself. [Where amber was not to be found.] Those among the Greeks who have devoted more attention to the subject, have spoken of certain islands in the Adriatic Sea, known as the “Electrides,” and to which the Padus, [In reality, these “Amber Islands” were situate at the mouth of the Vistula, into which the Radanus discharged itself; a river whose name was afterwards confounded with “Eridanus,” the ancient name of the Padus, or Po. See B. iv. cc. 27, 30, as to the produce of amber in the Baltic.] they say, carries down electrum. It is the fact, however, that there never were any islands there so called, nor, indeed, any islands so situate as to allow of the Padus carrying down anything in its course to their shores. As to Æschylus placing the Eridanus in Iberia, or, in other words, in Spain, and giving it the name of Rhodanus; and as to Euripides and Apollonius representing the Rhodanus and the Padus as discharging themselves by one common mouth on the shores of the Adriatic; we can forgive them all the more readily for knowing nothing about amber when they betray such monstrous ignorance of geography.

Other writers, again, who are more guarded in their assertions, have told us, though with an equal degree of untruthfulness, that, at the extremity of the Adriatic Gulf, upon certain inaccessible rocks there, there are certain trees [Another reference to its vegetable origin.] which shed their gum at the rising of the Dog-Star. Theophrastus [De Lapid. n. 53.] has stated that amber is extracted from the earth in Liguria; [In confirmation of this, Ajasson remarks that amber is found at Saint Paulet in the Department Du Gard, and at Aix, in the Department of Bouches-du-Rhône, regions not very distant from the territory of ancient Liguria.] Chares, that Phaëthon died in the territory of Hammon, in Æthiopia, where there is a temple of his and an oracle, and where amber is produced; Philemon, that it is a fossil substance, and that it is found in two different localities in Scythia, in one of which it is of a white and waxen colour, and is known as “electrum;” while in the other it is red, and is called “sualiternicum.” Demostratus calls amber “lyncurion,” [It has been supposed by some that this in reality was Tourmaline, and Woodward has identified it with Belemnites. See Beckmann, Hist. Inv. Vol. I. p. 86. Bohn’s Edition. See further as to “Lyncurium,” B. viii. c. 57, and Chapter of this Book.] and he says that it originates in the urine of the wild beast known as the “lynx;” that voided by the male producing a red and fiery substance, and that by the female an amber of a white and less pronounced colour: he also informs us that by some persons it is called “langurium,” and that in Italy, there are certain wild beasts known as “languri.” Zeuothemis, however, calls these wild beasts “langæ,” and gives the banks of the river Padus as their locality. Sudines says, that it is a tree in reality, that produces amber, and that, in Etruria, this tree is known by the name of “lynx;” an opinion which is also adopted by Metrodorus. Sotacus expresses a belief that amber exudes from certain stones in Britannia, to which he gives the name of “electrides.” Pytheas says that the Gutones, [See B. iv. c. 28.] a people of Germany, inhabit the shores of an estuary of the Ocean called Mentonomon, their territory extending a distance of six thousand stadia; that, at one day’s sail from this territory, is the Isle of Abalus, upon the shores of which, amber is thrown up by the waves in spring, it being an excretion of the sea in a concrete form; as, also, that the inhabitants use this amber by way of fuel, and sell it to their neighbours, the Teutones. Timæus, too, is of the same belief, but he has given to the island the name of Basilia. [See B. iv. c. 27.]

Philemon says that electrum does not yield a flame. [Said in reference to the electric spark, Ajasson thinks.] Nicias, again, will have it, that it is a liquid produced by the rays of the sun; and that these rays, at the moment of the sun’s setting, striking with the greatest force upon the surface of the soil, leave upon it an unctuous sweat, which is carried off by the tides of the Ocean, and thrown up upon the shores of Germany. He states, also, that in Egypt it is similarly produced, and is there called “sacal;” [In Hebrew, this word means “a stone.”] that it is found in India, too, where it is held as a preferable substitute for frankincense; and that in Syria the women make the whirls of their spindles of this substance, and give it the name of “harpax,” [From the Greek ἁρπάζω, “to drag.”] from the circumstance that it attracts leaves towards it, chaff, and the light fringe of tissues. According to Theochrestus, amber is thrown up by the tides of the Ocean, at the foot of the Pyrenæan range; an opinion adopted also by Xenocrates. Asarubas, who has written the most recently upon these subjects, and is still living, informs us, that near the shores of the Atlantic is Lake Cephisis, known to the Mauri by the name of “Electrum;” and that when this lake is dried up by the sun, the slime of it produces amber, which floats upon the surface. Mnaseas speaks of a locality in Africa called Sicyon, and of a river Crathis there, which discharges itself from a lake into the Ocean, the banks of which are frequented by birds which he calls “meleagrides” [See B. x. c. 38.] and “penelopes:” it is here that, according to him, electrum is produced, in manner above mentioned. Theomenes says that near the Greater Syrtis are the Gardens of the Hesperides, and Lake Electrum: on the banks, he says, are poplars, from the summits of which amber falls into the water below, where it is gathered by the maidens of the Hesperides.

Ctesias asserts that there is in India [All this is based, Ajasson thinks, upon the stories of Hindoo mythology.] a river called Hypobarus, a word which signifies “bearer of all good things;” that this river flows from the north into the Eastern Ocean, where it discharges itself near a mountain covered with trees which produce electrum; and that these trees are called “siptachoræ,” the meaning of which is “intense sweetness.” Mithridates says, that off the shores of Germany there is an island called “Serita,” [The old reading is “Osericta:” Ajasson identifies it with the island of Oësel in the Baltic.] covered with a kind of cedar, from which amber falls upon the rocks. According to Xenocrates, this substance is called, in Italy, not only “succinum,” but “thieum” as well, the Scythian name of it, for there also it is to be found, being “sacrium:” others, he says, are of opinion that it is a product of Numidia. But the one that has surpassed them all is Sophocles, the tragic poet; a thing that indeed surprises me, when I only consider the surpassing gravity of his lofty style, the high repute that he enjoyed in life, his elevated position by birth at Athens, his various exploits, and his high military command. According to him, amber is produced in the countries beyond India, from the tears that are shed for Meleager, by the birds called “meleagrides!” [See B. x. c. 38.] Who can be otherwise than surprised that he should have believed such a thing as this, or have hoped to persuade others to believe it? What child, too, could possibly be found in such a state of ignorance as to believe that birds weep once a year, that their tears are so prolific as this, or that they go all the way from Greece, where Meleager died, to India to weep? “But then,” it will be said, “do not the poets tell many other stories that are quite as fabulous?” Such is the fact, no doubt, but for a person seriously to advance such an absurdity with reference to a thing so common as amber, which is imported every day and so easily proves the mendacity of this assertion, is neither more nor less than to evince a supreme contempt for the opinions of mankind, and to assert with impunity an intolerable falsehood.

(3.) There can be no doubt that amber is a product of the islands of the Northern Ocean, and that it is the substance by the Germans called “glæsum;” [See B. iv. cc. 27, 30, and the Notes.] for which reason the Romans, when Germanicus Cæsar commanded the fleet in those parts, gave to one of these islands the name of Glæsaria, [See B. iv. c. 30.] which by the barbarians was known as Austeravia. Amber is produced from a marrow discharged by trees belonging to the pine [It is just possible that the Pinites succinifer may have still existed, to some extent, eighteen hundred years ago. See Note above.] genus, like gum from the cherry, and resin from the ordinary pine. It is a liquid at first, which issues forth in considerable quantities, and is gradually hardened by heat or cold, or else by the action of the sea, when the rise of the tide carries off the fragments from the shores of these islands. At all events, it is thrown up upon the coasts, in so light and voluble a form that in the shallows it has all the appearance of hanging suspended in the water. Our forefathers, too, were of opinion that it is the juice of a tree, and for this reason gave it the name of “succinum:” [From “succus,” “juice.”] and one great proof that it is the produce of a tree of the pine genus, is the fact that it emits a pine-like smell when rubbed, and that it burns, when ignited, with the odour and appearance of torch-pine wood.

Amber is imported by the Germans into Pannonia, more particularly; from whence the Veneti, by the Greeks called Eneti, first brought it into general notice, a people in the vicinity of Pannonia, and dwelling on the shores of the Adriatic Sea. From this it is evident how the story which connects it with the Padus first originated; and at the present day we see the female peasantry in the countries that lie beyond that river wearing necklaces of amber, principally as an ornament, no doubt, but on account of its remedial virtues as well; for amber, it is generally believed, is good for affections of the tonsillary glands and fauces, the various kinds of water in the vicinity of the Alps being apt to produce disease in the human throat. [Goitre, for example.]

From Carnuntum in Pannonia, to the coasts of Germany from which the amber is brought, is a distance of about six hundred miles, a fact which has been only very recently ascertained; and there is still living a member of the equestrian order, who was sent thither by Julianus, the manager of the gladiatorial exhibitions for the Emperor Nero, to procure a supply of this article. Traversing the coasts of that country and visiting the various markets there, he brought back amber, in such vast quantities, as to admit of the nets, which are used for protecting the podium [The projecting part in the Circus or Amphitheatre, next the arena, and immediately in front of the place occupied by the emperor and nobles.] against the wild beasts, being studded [The knots, probably, were adorned with studs or buttons of amber.] with amber.

The arms too, the litters, [“Libitina.” Meaning the litters on which the slain gladiators were carried away from the arena.] and all the other apparatus, were, on one day, decorated with nothing but amber, a different kind of display being made each day that these spectacles were exhibited. The largest piece of amber that this personage brought to Rome was thirteen pounds in weight.

That amber is found in India too, is a fact well ascertained. Archelaüs, who reigned over Cappadocia, says that it is brought from that country in the rough state, and with the fine bark still adhering to it, it being the custom there to polish it by boiling it in the grease of a sucking-pig. One great proof that amber must have been originally in a liquid state, is the fact that, owing to its transparency, certain objects are to be seen within, ants for example, gnats, and lizards. These, no doubt, must have first adhered to it while liquid, and then, upon its hardening, have remained enclosed within. [Martial has three Epigrams on Insects enclosed in amber; B. iv. Ep. 32 and 59, and B. vi. Ep. 15.]

Chap. 12.—The Several Kinds of Amber: The Remedies Derived from It.

There are several kinds [These so-called kinds or varieties are mostly accidental variations only in appearance.] of amber. The white is the one that has the finest odour; [Which is perceptible on its being rubbed: in some cases the odour of amber is very fine, in others it is perfectly fetid; though in the latter case, as Ajasson remarks, it is doubtful whether it may be considered to be genuine amber.] but neither this nor the wax-coloured amber is held in very high esteem. The red amber is more highly valued; and still more so, when it is transparent, without presenting too brilliant and igneous an appearance. For amber, to be of high quality, should present a brightness like that of fire, but not flakes resembling those of flame. The most highly esteemed amber is that known as the “Falernian,” from its resemblance to the colour of Falernian wine; it is perfectly transparent, and has a softened, transparent, brightness. Other kinds, again, are valued for their mellowed tints, like the colour of boiled honey in appearance. It ought to be known, however, that any colour can be imparted to amber that may be desired, it being sometimes stained with kid-suet and root of alkanet; indeed, at the present day, amber is dyed purple even. When a vivifying heat has been imparted to it by rubbing it between the fingers, amber will attract chaff, dried leaves, and thin bark, just in the same way that the magnet attracts iron. Pieces of amber, steeped in oil, burn with a more brilliant and more lasting flame than pith of flax. [“Lini.” Salmasius suggests “pini,” “pith of pine.”]

So highly valued is this as an object of luxury, that a very diminutive human effigy, made of amber, has been known to sell at a higher price than living men even, in stout and vigorous health. This single ground for censure, however, is far from being sufficient; in Corinthian objects of vertu, it is the copper that recommends them, combined with silver and gold; and in embossed works it is the skill and genius of the artist that is so highly esteemed. We have already said what it is that recommends vessels of murrhine and of crystal; pearls, too, are of use for wearing upon the head, and gems upon the fingers. In the case of all other luxuries, in fact, it is either a spirit of ostentation or some utility that has been discovered in them that pleads so strongly in their behalf; but in that of amber we have solely the consciousness that we are enjoying a luxury, and nothing more. Domitius Nero, among the other portentous extravagances of his life, bestowed this name upon the ringlets of his wife Poppæa, and, in certain verses of his, he has even gone so far as to call them “succini.” As fine names, too, are never wanting for bodily defects, a third tint has been introduced of late for hair among our ladies, under the name of “amber-colour.”

Amber, however, is not without its utility in a medicinal point of view; though it is not for this reason that the women are so pleased with it. It is beneficial for infants also, attached to the body in the form of an amulet; and, according to Callistratus, it is good for any age, as a preventive of delirium and as a cure for strangury, either taken in drink or attached as an amulet to the body. This last author, too, has invented a new variety of amber; giving the name of “chryselectrum” [“Golden amber.” Brotero thinks that this must have been Hyacinth or Zirconite of a yellowish white colour. Ajasson says that the description would equally apply to Idocrase, Meionite, or Harmotome.] to an amber of a golden colour, and which presents the most beautiful tints in the morning. This last kind attracts flame, too, with the greatest rapidity, and, the moment it approaches the fire, it ignites. “Worn upon the neck, he says, it is a cure for fevers and other diseases, and, triturated with honey and oil of roses, it is good for maladies of the ears. Beaten up with Attic honey, it is good for dimness of sight: and the powder of it, either taken by itself or with gum mastich in water, is remedial for diseases of the stomach. Amber, too, is greatly in request for the imitation of the transparent precious stones, amethystos in particular: for, as already stated, it admits of being dyed of every colour.

Chap. 13.—Lyncuruim: Two Asserted Remedies.

The pertinacity that has been displayed by certain authors compels me to speak of lyncurium [See Note, above. Brotero identifies it with orange-coloured Hyacinth; Ajasson and Desfontaines with Tourmaline. Ajasson suggests, also, that the first syllabic in its name— Lync, may have been derived from the Sanscrit Lanka, the name of Ceylon, one of the localities where the Tourmaline is chiefly found.] next; for even those who maintain that it is not a variety of amber, still assure us that it is a precious stone. They assert, too, that it is a product of the urine of the lynx and of a kind of earth, the animal covering up the urine the moment it has voided it, from a jealousy that man should gain possession of it; a combination which hardens into stone. The colour of it, they inform us, like that of some kinds of amber, is of a fiery [Ajasson thinks that Rubellite or Red Tourmaline is here alluded to.] hue, and it admits, they say, of being engraved. They assert, too, that this substance attracts [This is the case with tourmaline when subjected to heat.] to itself not only leaves or straws, but thin plates of copper even or of iron; a story which Theophrastus even believes, on the faith of a certain Diocles.

For my own part, I look upon the whole of these statements as untrue, and I do not believe that in our time there has ever been a precious stone seen with such a name as this. I regard, too, the assertions that have been made as to its medicinal properties, as equally false; to the effect that, taken in drink, it disperses urinary calculi, and that, taken in wine, or only looked at, it is curative of jaundice.

Chap. 14.—The Various Precious Stones, Classified According to Their Principal Colours.

We will now proceed to speak of the various kinds of precious stones, the existence of which is generally admitted, beginning with those which are the most highly esteemed. Nor shall we content ourselves with doing this only; but, with the view of consulting the general welfare of mankind, we shall also refute the infamous lies that have been promulgated by the magicians: for it is with reference to precious stones, more particularly, that they have circulated most of their fabulous stories, stepping, under that most alluring guise of ascertaining remedial virtues, beyond all bounds, and entering the region of the marvellous.

Chap. 15. (4.)—Adamas: Six Varieties of It. Two Remedies.

The substance that possesses the greatest value, not only among the precious stones, but of all human possessions, is adamas; [We may here remark, that throughout this Book, in all cases where there is any doubt as to the identification of the substance, the ancient name is retained. Hence our words “adamant” and “diamond.” If Pliny means the latter, which is doubtful, it still maintains the rank here assigned to it. The word “adamas” is supposed to be derived from the Greek ἀ, privative, and δαμάω, “to subdue,” it being supposed to be invincible by fire. The diamond is pure carbon crystallized, and is thought to have been of vegetable origin. Dana has the following remarks upon the word “adamas.”—“This name was applied by the ancients to several minerals differing much in their physical properties. A few of these are quartz, specular iron ore, emery, and other substances of rather high degrees of hardness, which cannot now be identified. It is doubtful whether Pliny had any acquaintance with the real diamond.”— System of Mineralogy, Art. Diamond. We may also add, from the same authority, that the method of polishing diamonds was first discovered in 1456, by Louis Berquen, a citizen of Bruges, previous to which time the diamond was only known in its native uncut state.] mineral which, for a long time, was known to kings only, and to very few of them. Such was the name given to a nodosity of gold, [This statement cannot apply to the “diamond” as known to us, though occasionally grains of gold have been found in the vicinity of the diamond.] sometimes, though but rarely, found in the mines, in close proximity with gold, and only there to be found, it was thought. The ancients supposed that adamas was only to be discovered in the mines of Æthiopia, [Ajasson is of opinion that the Æthiopia here mentioned is in reality India, and that the “Temple of Mercury” means the Brahmaloka, or Temple of Brahma.] between the Temple of Mercury and the island of Meroë; and they have informed us that it was never larger than a cucumber-seed, or differing at all from it in colour.

At the present day, for the first time, there are no less than six different varieties of it recognized. The Indian adamas is found, not in a stratum of gold, but in a substance of a kindred nature to crystal; which it closely resembles in its transparency and its highly polished hexangular and hexahedral [The diamond, as known to us, is octahedral.] form. In shape it is turbinated, running to a point at either extremity, and closely resembling, marvellous to think of, two cones united at the base. In size, too, it is as large even as a hazel-nut. Resembling that of India, is the adamas [Though found in comparative abundance in India, the diamond is not found in Arabia.] of Arabia, which is found in a similar bed, but not so large in size. Other varieties have a pallid hue like that of silver, and are only to be found in the midst of gold of the very finest quality. These stones are tested upon the anvil, and will resist the blow to such an extent, as to make the iron rebound and the very anvil split asunder. [This is not the case with the diamond; for on being struck under such circumstances, it will break.] Indeed its hardness is beyond all expression, while at the same time it quite sets fire at defiance [In reality, the diamond will burn, and, at a temperature of 14° Wedgewood, is wholly consumed, producing carbonic acid gas.] and is incapable of being heated; owing to which indomitable powers it is, that it has received the name which it derives from the Greek. [See Note, above.]

One kind, about as large as a grain of millet in size, has been called “cenchros,” [“Millet-seed.”] and another, [Ajasson says, that no doubt this adamas was Adamantine, or limpid Corundum.] that is found in the gold mines at Philippi, is known as the “Macedonian” adamas: this last is about as large as a cucumber-seed in size. We next come to the Cyprian [Ajasson suggests that this may have been Dichroite, or Cordierite, known also as Iolite, or Water sapphire.] adamas, so called from its being found in the Isle of Cyprus: it is of a colour somewhat inclining to that of copper, but, in reference to its medicinal virtues, of which we shall have to make further mention, it is the most efficacious of them all. Next in succession to this we have siderites, [Possibly the Siderite, sparry iron, or spathic iron of modern Mineralogy. Ajasson is inclined to think that it is Corundum, of a dark hue.] a stone which shines like iron, and is more ponderous than any of the others, but differs in its properties from them all. For it breaks when struck by the hammer, and admits of being perforated by other kinds of adamas; a thing which is the case, also, with that of Cyprus: in short, these two are degenerate stones, and only bear the name of “adamas” for the purpose of enhancing their value.

Now with reference to those affinities and repugnances which exist between certain objects, known to the Greeks as “sympathia” and “antipathia,” phænomena to which we have endeavoured [See B. xx. c. 1, B. xxviii. cc. 23, 41, and B. xxxii. c..] to draw attention throughout these books, they nowhere manifest themselves with greater distinctness than here. This indomitable power, in fact, which sets at nought the two most violent agents in Nature, fire, namely, and iron, is made to yield before the blood of a he-goat. [Brotero thinks that this was a story invented by the dealers, with a view of concealing the real method of breaking the stone.] The blood, however must be no otherwise than fresh and warm; the stone, too, must be well steeped in it, and then subjected to repeated blows: and even then, it is apt to break both anvils and hammers of iron, if they are not of the very finest temper. To what spirit of research, or to what accident, are we indebted for this discovery? or what conjecture can it have been, that first led man to experiment upon a thing of such extraordinary value as this, and that, too, with the most unclean [Said, probably, with reference to the rank, nauseous smell of the he-goat.] of all animals? Surely a discovery, such as this, must have been due solely to the munificence of the gods, and we must look for the reason of it in none of the elementary operations of Nature, but wholly in her will.

When, by good fortune, this stone does happen to be broken, it divides into fragments so minute as to be almost imperceptible. These particles are held in great request by engravers, who enclose them in iron, and are enabled thereby, with the greatest facility, to cut [This is true with reference to the diamond, and, in a less degree, several other crystalline substances, emery and quartz, for example.] the very hardest substances known. So great is the antipathy borne by this stone to the magnet, that when placed near, it will not allow of its attracting iron; or if the magnet has already attracted the iron, it will seize the metal and drag it away from the other. [Ajasson remarks, that if the diamond is placed in the magnetic line or current of the loadstone, it attracts iron equally with the loadstone, and consequently neutralizes the attractive power of the loadstone in a considerable degree.] Adamas, too, overcomes and neutralizes poisons, dispels delirium, and banishes groundless perturbations of the mind; hence it is that some have given it the name of “ananchites.” [The reading is very doubtful here. This word, as it is here given, would appear to be derived from the Greek ἀ privative, and ἄγχομαι, “to strangle oneself,” and to mean, “preventive of suicide.”] Metrodorus of Scepsis is the only author, that I know of, who says that this stone is found also in Germany, and in the island of Basilia, [See B. iv. c. 27, and Chapter of this Book.] where amber is found. He says, too, that this is preferable to the stone of Arabia; but can there be any doubt that his statement is incorrect?

Chap. 16.—-Smaragdus.

Next [At the present day the ruby is next in esteem to the diamond.] in esteem with us are the pearls of India and Arabia, of which we have already spoken in the Ninth Book, [Chapter, et seq.] when treating of the marine productions.

(5.) The third rank, for many reasons, has been given to the smaragdus. [The Emerald, and various other green precious stones, were included under this name.] Indeed there is no stone, the colour of which is more delightful to the eye; for whereas the sight fixes itself with avidity upon the green [“Virentes” seems a very preferable reading to “silentes,” as given by the Bamberg MS.] grass and the foliage of the trees, we have all the more pleasure in looking upon the smaragdus, there being no green in existence of a more intense colour [The emerald is supposed to derive this colour from a minute portion of oxide of chrome.] than this. And then, besides, of all the precious stones, this is the only one that feeds the sight without satiating it. Even when the vision has been fatigued with intently viewing other objects, it is refreshed by being turned upon this stone; and lapidaries know of nothing that is more gratefully soothing to the eyes, its soft green tints being wonderfully adapted for assuaging lassitude, when felt in those organs.

And then, besides, when viewed from a distance, these stones appear all the larger to the sight, reflecting as they do, their green hues upon the circumambient air. Neither sunshine, shade, nor artificial light effects any change in their appearance; they have always a softened and graduated brilliancy; and transmitting the light with facility, they allow the vision to penetrate their interior; a property which is so pleasing, also, with reference to water. In form they are mostly concave, so as to re-unite the rays of light and the powers of vision: and hence it is, that it is so universally agreed upon among mankind to respect these stones, and to forbid their surface [Engraved emeralds are but seldom found among collections of ancient gems. In 1593, there was one found in the tomb of Maria, daughter of Stilicho, in the Vatican, with the head of Honorius, her husband, engraved upon it.] to be engraved. In the case, however, of the stones of Scythia and Egypt, their hardness is such, that it would be quite impossible to penetrate them. When the surface of the smaragdus is flat, it reflects the image of objects in the same manner as a mirror. The Emperor Nero used to view [“It may here be objected that real emeralds are too small to admit of being used as mirrors; but the ancients speak of some sufficiently large for that purpose, and also of artificial ones; so that we may with certainty conclude, that they classed among the emeralds fluor spar, green vitrified lava, or the green Icelandic agate, as it is called, green jasper, and also green glass.”—Beckmann, Hist. Inv. Vol. II. p. 67. Bohn’s Edition. It has also been suggested, with reference to this passage, that Nero was short-sighted, and that this emerald was formed like a concave lens. The passage, however, will hardly support such a construction. Ajasson thinks that it must have been a Dioptase or Siberian emerald; or else a green Corundum.] the combats of the gladiators upon a smaragdus.

Chap. 17.—Twelve Varieties of the Smaragdus.

Of this stone there are no less than twelve different kinds; of which the finest is the Scythian [Ajasson is of opinion that the Dioptase, Siberian emerald, or Malachite emerald is meant.] smaragdus, so called from the country where it is found. None of them has a deeper colour than this, or is more free from defects: indeed, in the same degree that the smaragdus is superior to other precious stones, the Scythian smaragdus is superior to the other varieties. Next in esteem to this, as also in locality, is the smaragdus of Bactriana. [Ajasson thinks that this may be the Dioptase or Achirite of Chinese Bucharia; and that the merchant Achir Mahmed, from whom it takes its name, was by no means the first to introduce it, or to circulate his wonderful stories as to its formation.] These stones are collected, it is said, in the fissures of rocks, when the Etesian [See B. ii. cc. 47, 48, and B. xviii. c. 74.] winds prevail; a period at which the earth that covers them is removed, and the stones are detected by their brightness, the sands being greatly agitated by the action of the winds. These last, however, are much inferior, they say, to those of Scythia in size. The third rank is held by the stones of Egypt, [Mount Zalora. in Upper Egypt, still produces emeralds, and was probably the only locality of the genuine stone that was known to the ancients.] which are extracted from the hills in the vicinity of Coptos, a city of Thebais.

All the other kinds are found in copper-mines, and hence it is that, of these varieties, the smaragdus of Cyprus holds the highest rank. The merit of them consists in their clear colour, which has nothing thin or diluted in it, but presents a rich and humid transparency, closely resembling the tints of the sea, in fact. Hence it is that these stones are at once diaphanous and shining, or, in other words, reflect their colours and allow the vision to penetrate within. They say that in this island, upon the tomb of a petty king named Hermias, near the fisheries [“Cetarias.”] there, there was formerly a lion in marble, with eyes made of smaragdi; the brilliancy of which penetrated the sea to such a degree, as to alarm the tunnies and put them to flight: a novel circumstance, which for a long time excited wonder in the fishermen, till at last the stones in the statue were changed for others.
