Having now described the principal precious stones, classified according to their respective colours, I shall proceed to mention the rest of them in their alphabetical order.

(10.) Achates3204 was a stone formerly in high esteem, but now held in none. It was first found in Sicily, near a river of that name; but has since been discovered in numerous other localities. In size it exceeds any other stones of this class, and the varieties of it are numerous, the name varying accordingly. Thus, for example, we have iaspachates,3205 cerachates,3206 smaragdachates,3207 hæmachates,3208 leucachates,3209 dendrachates,3210 marked with small shrubs, as it were; autachates,3211 which when burnt has a smell like that of myrrh; and coralloachates,3212 spotted all over, like sapphiros, with drops of gold, and commonly found in Crete, where it is also known as “sacred” achates. This last, it is thought, is good for wounds inflicted by spiders and scorpions; a property which I could really believe to belong to the stones of Sicily, for, the moment they breathe the air of that province, scorpions lose their venom.

The stones, too, that are found in India are possessed of similar properties, and of other great and marvellous properties as well; for they present the appearance in them of rivers,3213 woods,3214 beasts of burden, and forms even, like ivy3215 and the trappings of horses. Medical men, too, make grinding-hones3216 of these stones, and indeed the very sight of them is beneficial for the eyes: held in the mouth, they allay thirst. Those found in Phrygia have no green in them, and those of Thebes in Egypt are destitute of red and white veins. These last are good as a counterpoison to the venom of the scorpion, and the stones of Cyprus are held in similar repute. Some persons set the highest value upon those stones which present a transparency like that of glass. They are found also in Trachinia, in the vicinity of Mount Œta, upon Mount Parnassus, in the Isle of Lesbos, in Messene, where they resemble the flowers that grow in the hedges, and at Rhodes.

The magicians make other distinctions in reference to these stones: those, they tell us, which have spots upon them like the spots on the lion’s skin, are efficacious as a protection against scorpions; and in Persia, they say, these stones are used, by way of fumigation, for arresting tempests and hurricanes, and for stopping the course of rivers, the proof of their efficacy being their turning the water cold, if thrown into a boiling cauldron. To be duly efficacious, they must be attached to the body with hairs from a lion’s mane. The hair, however, of the hyæna is held in abomination for this purpose, as being a promoter of discord in families. The stone that is of an uniform colour renders athletes invincible, they say: the way of testing it is to throw it, along with colouring matter, into a pot full of oil; after being kept for a couple of hours gently on the boil, if genuine, it will impart an uniform colour of vermilion to the mixture.

Acopos3217 is a stone like nitre3218 in appearance, porous, and starred with drops of gold: gently boiled with oil and applied as an unguent, it relieves lassitude, if we choose to believe it. Alabastritis3219 is a stone which comes from Alabastron in Egypt and Damascus in Syria: it is of a white colour, spotted with various other tints. Calcined with fossil salt and pulverized, it is a cure for affections of the mouth and teeth, it is said. Alectoria3220 is the name given to a stone that is found in the crop of poultry, like crystal in appearance, and about as large as a bean in size: Milo3221 of Crotona, some will have it, was thought to be in the habit of carrying this stone about him, a thing that rendered him invincible in his athletic contests. Androdamas3222 has the shining colour of silver, like adamas;3223 it is always quadrangular, like small cubes in shape. The magicians are of opinion that it was thus named from the fact that it subdues anger and violence in man. Whether argyrodamas3224 is the same stone or not, authors do not inform us. Antipathes3225 is a black stone, and not transparent: the mode of testing it, is by boiling it in milk, to which, if genuine, it imparts a colour like that of myrrh. A person might probably expect to find some extraordinary virtues in this stone, seeing that, among so many other substances possessed of antipathetic properties, it is the only one that bears this name. The magicians will have it that it possesses the power of counteracting fascinations.

Arabica3226 is a stone which closely resembles ivory in appearance, and, indeed, might easily be taken for it, were it not for its superior hardness: persons who have this stone about them, it is thought, will experience a cure of diseases of the sinews. Aromatitis,3227 too, is a stone that is found in Arabia, as also in the vicinity of Phiræ in Egypt: it is always full of small stones, and like myrrh in colour and smell, a thing that makes it much in request with ladies of rank.3228 Asbestos3229 is found in the mountains of Arcadia, and is of an iron colour. Democritus informs us that aspisatis3230 is a native of Arabia, that it is of a fiery colour, and that patients should wear it attached to the body with camels’ dung; he says, too, that it is found in the nests of certain birds3231 in Arabia. The same writer also mentions another stone of this name, that is found at Leucopetra in the same country, of a silver colour, radiant, and an excellent preservative against delirium. In India, he says, and on Mount Acidane in Persia, there is a stone found that is known as “atizoë,”3232 of a silver lustre, three fingers in length, like a lentil in shape, possessed of a pleasant smell, and considered necessary by the Magi at the consecration of a king. Augetis3233 is thought by many to be identical with callaina.3234 Amphidanes,3235 which is also known as “chrysocolla,”3236 is a stone found in that part of India where the ants3237 throw up gold, and in it there are certain square pieces, like gold in appearance. The nature of this stone, it is asserted, is similar to that of the magnet; in addition to which, it is said to have the property of increasing gold.

Aphrodisiaca3238 is a stone of a reddish white colour. Apsyctos,3239 when heated by fire, retains the warmth so long as seven days; it is black and ponderous, and is streaked with red veins. It is good too, it is thought, as a preservative against cold. According to Iacchus, Ægyptilla3240 is a kind of white and black sarda, intersected with veins; but the stone commonly known by that name is black at the lower part, and azure on the surface. It takes its name from the country that produces it.
