Marbles are of many different kinds, usually named either from their color or country; some of one simple color, as white, or black; others streaked or variegated with different colors. They are cla.s.sified as ancient and modern: the ancient are those found in quarries now lost or inaccessible to us, and of which there are only some wrought pieces remaining;--the modern, those from quarries still open, and out of which blocks of marble continue to be taken.
In what countries is Marble found?
The United States, Great Britain, France, Spain, Italy, Africa, Egypt, and many other countries, produce marbles of different colors and qualities; some more beautiful, valuable, and more highly esteemed than others, as those of Egypt, Italy, &c. Those, also, of different places in the same country frequently differ from each other in quality and appearance Of the European marbles, that of Italy is the most valuable.
What kind appears to have been held in the greatest esteem by the ancients?
A beautiful white marble, called the Parian; of which the Grecian statues were mostly made. By some, it is supposed to have taken its name from the Isle of Paros, in the Mediterranean; but by others from Parius, a famous statuary, who made it celebrated by cutting in it a statue of Venus. Parian marble is often mentioned by ancient authors.
_Statues_, figures of men, animals, &c., cut in stone or marble.
_Statuary_, one who makes statues.
Who was Venus?
The G.o.ddess of love and beauty, who was an object of adoration in the idolatrous ages, when men ignorantly knelt down and worshipped stocks and stones, which their own hands had fashioned after the likeness of things on the earth, or imaginary creations of their fancy;--or, again, the sun, moon, and stars, instead of the one and only true G.o.d.
In those times, every nation had its peculiar deities, to whom were paid divine rites and honors, and to whose names costly temples were dedicated: these deities were divided into two cla.s.ses, superior and inferior. Venus was one of the Grecian G.o.ddesses, supposed by them to have sprung from the froth of the sea. Kings and celebrated warriors, and sages too, after death, frequently received divine honors; as Confucius, the founder of the Chinese empire, who, after death, was worshipped by that people as a G.o.d. Romulus, the first king of Rome, likewise, was thus adored by the Romans; and many similar instances of the same species of idolatry amongst other nations might be recorded.
_Deities_, fabulous G.o.ds or G.o.ddesses.
_Idolatrous_, given to the worship of idols.
_Superior_, higher in rank.
_Inferior_, of a lower rank.
_Sage_, a wise man.
CHAPTER XIV.
GOLD, SILVER, LEAD, TIN, PLATINA, SULPHUR, GEMS OR PRECIOUS STONES, AS DIAMONDS, RUBIES, EMERALDS, TURQUOIS, PEARLS, MOTHER-OR-PEARLS, AND IVORY.
What is Gold?
The purest and most precious of metals: it is sometimes found in solid ma.s.ses, as in California, Peru, Hungary, &c.; in a shape resembling the branches of plants; in thin plates covering other bodies, as in Siberia; sometimes in a crystal form. It, however, generally occurs in a metallic state, and most commonly in the form of grains.
What is it called when found in a perfect metallic form?
Native gold: it is, however, seldom met with perfectly pure, being frequently alloyed with silver, copper, iron, or platina; sometimes concealed in other minerals; from which, if sufficiently abundant, it is extracted by art.
Where and in what manner is Gold generally found?
All parts of the earth afford gold; though with great difference in point of purity and abundance. It is chiefly obtained from mines. Many rivers contain gold in their sands, especially those of California and Guinea. Gold mines are of rare occurrence in Europe, but the metal is found in some of its rivers; among its mines, those of Upper Hungary are the most considerable. China and j.a.pan are rich in this metal; many parts of Asia also possess it. Australia produces quant.i.ties of the metal. It is also found in the eastern parts and interior of Africa, where gold dust is collected in great quant.i.ties from earth deposited by the rivers. But it is in America that gold is found in the greatest abundance, particularly in the State of California, and in some parts of South America, as Brazil, Peru, Chili, &c.
_Guinea_, a country of Western Africa.
What are the uses of Gold?
It is used for money, jewelry, plate, &c. It is also employed in various ways in the arts.
What is the character of Gold?
Gold is so ductile and malleable, that an ounce of it may be drawn into a thread of 73 leagues in length; or beaten into 160 leaves of 9 inches square, and thin enough to be carried away by the slightest wind. It readily a.s.sumes any form that human art can bestow upon it: its color is unalterable, and the beautiful polish of which it is susceptible, renders it the best of all metals for ornamental purposes. It is indestructible by air, water, or fire. Gold is the heaviest of all metals, except platina; it is neither very elastic, nor very hard.
_League_, a measure of length containing three miles.
_Indestructible_, incapable of being destroyed.
Is not the use of Gold quite ancient?
Yes; it appears to have been very early known to the inhabitants of the world. In the 13th Chapter of Genesis, Abram is spoken of as very rich in silver and gold; and in the 2d Chapter of the same book, the "land of Hevilath" (now in the eastern part of Arabia Felix,) is pointed out as having gold. Arabia was famed for the fineness and quality of its gold. In the time of Solomon, the gold of Ophir seems to have been much esteemed, as it is recorded that the gold used in the building of the Temple was brought from that place by the merchant-vessels of Hiram, King of Tyre. Ophir is supposed to have been situated somewhere in the East Indies.
What is Silver?
A beautiful white shining metal, next to gold in value, and, like that precious substance, of great antiquity. It is found in Sweden, Norway, and the polar lat.i.tudes: when it occurs in hot climates, it is generally amidst mountains, covered with perpetual snow.
_Lat.i.tude_, breadth, width; in Geography, the distance of a place in degrees, north or south, from the Equator.
Where are the richest Silver Mines found?
In South America, especially among the Andes; the mines of Mexico, and those of Nevada, also, are rich in this metal. The richest and most important silver mines in Europe are those of Konigsberg, in Norway, and of Andalusia, in Spain. With the exception of gold, silver is the most ductile of all metals: a single grain may be extended into a plate 126 inches long, and half an inch broad. It is capable of still further extension, but its tenacity is inferior even to that of iron or copper. A silver wire one-tenth of an inch thick will scarcely bear a weight of 290 pounds, whilst a gold wire of the same thickness will support nearly double that weight. Like some other metals, it is unalterable by air or moisture, but by an intense heat may be volatilized, being sometimes found in the soot of chimneys where large quant.i.ties are melted.
_Volatilized_, made to fly off by evaporation.
In what state is Silver usually found?
It is rarely found in a state of purity, being generally mixed with other metals, as gold, lead, &c. Ma.s.ses of native silver are of no determinate form; being found sometimes in small branches, sometimes in threads, or very frequently in leaves, as in the Siberian mines.
Native, or pure silver is chiefly found in the mines of Potosi. Silver was used as money in commerce 1100 years before the foundation of Rome.
_Commerce_, trade of one nation with another, or different persons, &c. with each other.
What is Tin?
