The Alexandrian Library was the largest and most famous of all the ancient collections of books. It was founded by Ptolemy Soter, King of Egypt, who died in 283 BC, and greatly enlarged by succeeding Ptolemies. At its most flourishing period it is said to have numbered 700,000 volumes, accommodated in two different buildings, one of them being the Serapeion, or temple of JupiterSerapis. The other collection was burned during Julius Caesar's siege of the city, but the Serapeion library existed to the time of the Emperor Theodosius the Great, when, at the general destruction of the heathen temples, the splendid temple of JupiterSerapis was gutted in 391 by a fanatical crowd of Christians, and its literary treasures destroyed or scattered. A library was again accumulated, but was burned by the Arabs when they captured the city under the caliph Omar in 611. Amru, the captain of the caliph's army, would have been willing to spare the library, but Omar is said to have disposed of the matter in the famous words: 'If these writings of the Greeks agree with the Koran they are useless, and need not be preserved; if they disagree they are pernicious, and ought to be destroyed.'

In sculpture, a colossus is a statue of enormous magnitude. The Asiatics, the Egyptians, and in particular the Greeks, have excelled in these works. The most celebrated Egyptian colossus was the vocal statue of Memnon in the plain of Thebes, supposed to be identical with the most northerly of two existing colossi (60 feet high) on the west bank of the Nile.
Among the colossi of Greece the most celebrated was the Colossus of Rhodes, a brass statue of Apollo 70 cubits high, esteemed one of the wonders of the world, erected at the port of Rhodes by Chares, 290 or 288 BC. It was knocked down by an earthquake about 224 BC. The statue was in ruins for nearly nine centuries, when the Saracens, taking Rhodes, sold the metal, weighing 720,900 lbs, to a Jew, about 653. There is no authority for the popularly-received statement that it bestrode the harbour mouth, and that the Rhodian vessels could pass under its legs.
Among the colossi of Phidias were the Olympian Zeus and the Athena of the Parthenon; the former 60 feet high and the latter 40 feet.
The most famous of the Roman colossi were the Jupiter of the Capitol, the Apollo of the Palatine Library, and the statue of Nero, 110 or 120 feet high, and from which the contiguous amphitheatre derived its name of Colosseum.
Among modern works of this nature is the colossus of San Carlo Borromeo, at Arona, in the Milanese territory, 60 feet in height; the 'Bavaria' at Munich, 65 feet high; the statue of Hermann or Arminius near Detmold, erected in 1875, 90 feet in height to the point of the upraised sword, which itself is 24 feet in length; the height of the figure to the point of the helmet being 55 feet;
the statue of Germania, erected in 1883 near Rudesheim, a figure 34 feet high, placed on an elaborately-sculptured pedestal over 81 feet high; and Bartholdi's statue of Liberty presented to the United States by the French nation, and which measures 104 feet or to the extremity of the torch in the hand of the figure 138 feet. It is erected at New York harbour on a pedestal 114 feet, is constructed for a lighthouse with what was at one time was one of the most powerful fixed lights in the world, and stands 317 feet above mean tide.

A comet is a small body orbiting the sun on an elliptical path with a long tail of dust and ice.
Some comets are only visible by the aid of the telescope, while others can be seen by the naked eye. In the latter case they usually appear like stars accompanied with a train of light, sometimes short and sometimes extending over half the sky, mostly single and more or less curved, but sometimes forked. In a comet which appeared in 1744 the train was divided into several branches, spreading out from the head like a fan. The train is not stationary relatively to the head, but is subject to remarkable movements. The direction in which it points is always opposite to the sun, and as the , comet passes its perihelion the train changes its apparent position with extraordinary velocity. The head of the comet is itself of different degrees of luminosity, there being usually a central core, called the nucleus, of greater brilliancy than the surrounding envelope, called the coma.
Comets were long regarded as supernatural objects, and usually as portents of impending calamity. Tycho Brahe was the first who expressed a rational opinion on the subject, coming to the conclusion that the comet of 1577 was a heavenly body at a greater distance from the earth than that of the moon. The general law of the motion of bodies, as well as his own observations on the comet of 1680, led Isaac Newton to conclude that the orbits of the comets must, like those of the planets, be ellipses, having the sun in one focus, but far more eccentric; and having their aphelions, or greater distances from the sun, far remote in the regions of space.
This idea was taken up by Halley, who collated the observations which had been made of all the twenty-four comets of which notice had been taken previous to 1680. The results were very interesting. With but few exceptions the comets had passed within less than the earth's shortest distance from the sun, some of them within less than one-third of it, and the average about one-half. Out of the number, too, nearly two-thirds had had their motions retrograde, or moved in the opposite direction to the planets. While Halley was engaged on these comparisons and deductions the comet of 1682 made its appearance, and he found that there was a wonderful resemblance between it and three other comets that he found recorded - the comets of 1456, of 1531, and of 1607. The times of the appearance of these comets had been at very nearly regular intervals, the average period being between seventy-five and seventy-six years. Their distances from the sun, when in perihelion, or when nearest to that luminary, had been nearly the same, being nearly six-tenths of that of the earth, and not varying more than one-sixtieth from each other.
The inclination of their orbits to that of the earth had also been nearly the same, between 17 degrees and 18 degrees; and their motions had all been retrograde. Putting these facts together, Halley concluded that the comets of 1456, 1531,1607, and 1682 were reappearances of one and the same comet, which revolved in an elliptic orbit round the sun, performing its circuit in a period varying from a little more than seventy-six years to a little less than seventy-five; or having, as far as the observations had been carried, a variation of about fifteen months in the absolute duration of its year, measured according to that of the earth. For this variation in the time of its revolution Halley accounted upon the supposition that the form of its orbit had been altered by the attraction of the remote planets Jupiter and Saturn as it passed near to them; and thence he concluded that the period of its next appearance would be lengthened, but that it would certainly reappear in 1758 or early in 1759. As the time of its expected reappearance approached, Clairaut calculated that it would be retarded 100 days by the attraction of Saturn, and 518 by that of Jupiter, so that it would not come to the perihelion, or point of its orbit nearest the 500 sun, until the 13th of April, 1759.
It actually reached its perihelion on the 13th of March, 1759, being thirty days earlier than he had calculated. Along with the period of this comet and its perihelion distance, the magnitude and form of its path were also calculated. Estimating the mean distance of the earth from the sun at 95,000,000 miles (the number which was at that time considered as the true one), the mean distance of the comet was calculated to be 1,705,250,000 miles; its greatest distance from the sun, 3,355,400,000; its least distance, 55,100,000; and the transverse or largest diameter of its orbit, 3,410,500,000. This comet, therefore, is a body belonging to the solar system, and quite beyond the attraction of any body which does not belong to that system; and as this is determined of one comet, analogy points it out as being the case with them all. In 1835 it again returned, being first seen at Rome, on August the 5th, and from that time continued to be observed until the end of the year in Europe, and through a great part of spring 1836 in the southern hemisphere.
The comet denominated Encke's comet, which has made repeated appearances, was first observed in 1818, and was identified with a comet observed in 1786, also with a comet discovered in 1795 by Miss Herschel in the constellation Cygnus, and with another seen in 1805. Its orbit is an ellipse of comparatively small dimensions, wholly within the orbit of Jupiter; its period is 1260 days, or about three years and three-tenths. It has been frequently observed since.
Another comet, the history of which is of the utmost importance in the latest theories regarding the connection of these bodies and the periodic showers of shooting-stars, is one known as Biela's comet, discovered in 1826. It revolved about the sun in about 6.75 years, and was identified as the same comet which was observed in 1772 and in 1806. Its returns were noted in 1832, 1839, and 1845. In 1846 it divided into two, returned double in 1852, but has not since been seen, the Supposition being that it has been dissipated, and that it was represented by a great shower of meteors that were seen in November 1872. One of the most remarkable comets of recent times was that known as Donati's, discovered by Dr. Donati of Florence in 1858. It was very brilliant in England in the autumn of that year, and on the 18th of October was near coming into collision with Venus, The year 1881 was remarkable for the number of comets recorded. During that year no fewer than seven comets, including the well-known short-period comet Encke's, were observed. Research Comet
The Ptolemaic system was a system of astronomy set forth by the Egyptian astronomer Clausius Ptolemaeus during the 11th century. By the Ptolemaic system the earth is fixed in the centre of the universe and the heaves revolve around the earth from east to west, carrying with them the sun, planets and fixed stars in their respective spheres. The system says that the Moon is next above the earth, then Mercury, then Venus; the Sun is next then Mars, and then after MarsJupiter and Saturn, beyond Saturn are two crystalline spheres.
It was the nonsense of the Ptolemaic system that Copernicus proved wrong and was so persecuted for until his system was adopted in the sixteenth century. Research Ptolemaic System
The week is the period of seven days now universally adopted. It is of Hebrew or Chaldean origin and is generally regarded as a memorial of the creation of the world according to the Mosaic account. Dion Cassius attributes the invention of the week to the Egyptians. The Ptolemaic arrangement of the heavenly bodies, according to their distances from the earth, is Saturn (the most distant), Jupiter, Mars, the sun, Venus, Mercury and the Moon; and it was a principle of the ancient astrology that these bodies presided in this succession over the hours of the day. If the first hour be assigned to Saturn, the twenty-fifth or first hour of the next day, will fall to the sun; the forty-ninth, or first hour of the second day will fall to the moon and so on. From the names of the planets have been formed the modern names - Saturday (Saturn), Sunday (Sun), Monday (Moon), Tuesday (Tiu, the Saxonequivalent of Mars), Wednesday (Woden the Norseequivalent of Mercury), Thursday (Thor the Norseequivalent of Jupiter) and Friday (Frygga the Norseequivalent of Venus).

The zodiac was the name given by the ancient Greeks to the heavens. It was an imaginary belt in the celestial sphere, extending about 80 degrees on either side of the ecliptic, the apparent path of the Sun among the stars. The width of the zodiac was determined originally so as to include the orbits of the Sun and Moon and of the five planets (Mercury, Venus, Mars, Jupiter, and Saturn) that were known to the people of ancient times.
The zodiac is divided into 12 sections of 300 degrees each, which are called the signs of the zodiac. Starting with the vernalequinox and then proceeding eastward along the ecliptic, each of the divisions is named for the constellation situated within its limits in the second century BC. The names of the zodiacal signs are Aries, the Ram; Taurus, the Bull; Gemini, the Twins; Cancer, the Crab; Leo, the Lion; Virgo, the Virgin; Libra, the Balance; Scorpio, the Scorpion; Sagittarius, the Archer; Capricorn, the Goat; Aquarius, the Water Bearer; and Pisces, the Fish. Because of the precession of the equinoxes about the ecliptic, a 26,000-year cycle, the first point of Aries retrogrades about 10 degrees in 70 years, so that the sign Aries today lies in the constellationPisces. In about 24,000 years, when the retrogression will have completed the entirecircuit of 3600, the zodiacal signs and constellations will again coincide.
It is believed that the zodiacal signs originated in Mesopotamia as early as 2000 BC . The Greeks adopted the symbols from the Babylonians and passed them on to the other ancient civilisations. The Egyptians assigned other names and symbols to the zodiacal divisions. The Chinese also adopted the 12-fold division, but called the signs rat, ox, tiger, hare, dragon, serpent, horse, sheep, monkey, hen, dog, and pig. Independently, the Aztec Indians devised a similar system. Research Zodiac
Edward Gibbon was an English writer and historian. He was born in 1737 at Putney and died in 1794. He was the son of a gentleman of an ancient Kentish family. He entered Magdalen College, Oxford, where he remained for fourteen mouths. Having declared himself a Roman Catholic, his father placed him under the care of Pavillard, a learned Calvinistic minister at Lausanne, by whom he was reconverted to the Protestant faith. His residence at Lausanne was highly favourable to his progress in knowledge and the formation of regular habits of study. The belles-lettres and the history of the humanmind chiefly occupied his attention. In 1758 he returned to England, and immediately began to lay the foundation of a copious library; and soon after composed in the French language his Essai sur l'Etude de la Litterature (published in 1761).
In 1763 he visited Paris and Lausanne, and he journeyed in Italy during 1764. It was here that the idea of writing his great history occurred to him as he sat musing among the ruins of the capitol at Rome, while the barefooted friars were singing vespers in the Temple of Jupiter. In 1770 he published a pamphlet entitled Critical Observations on the Sixth Book of the AEneid. In 1774 he obtained a seat in parliament for Liskeard, and was a silent supporter of the North administration and its American politics for eight years.
In 1776 the first quarto volume of his Decline and Fall of the Roman Empire was published, and at once made a public reputation for its author. In 1778 he drew up on behalf of the English government a Memoire Justificatif in answer to the manifesto of the French court, and for this service he was made one of the lords of trade. On the retirement of North he lost his appointment, and soon after withdrew to Lausanne in 1783, where, in the course of four years, he completed the three remaining volumes of his history, which were published together in 1788.
In 1793 he returned to England, where he died on the 16th of January, 1794. His history, though not without its defects, has great merits. Its style, if at times somewhat stiff and pompous, has the energy and elevation required for so great a theme; his learning is vast and thorough, and his insight into human nature in every variety of circumstances in remote countries and epochs is that of a great and philosophical historian. In 1796 his friend LordSheffield published two quarto volumes of his miscellaneous works, of which the most valuable part is the Memoirs of his Life and Writings. Research Edward Gibbon
Among the ancient Romans Flamen was the name given to any priest devoted to the service of one particular deity. Originally there were three priests so called: the Flamen Dialis, consecrated to Jupiter; Flamen Martialis, sacred to Mars; and Flamen Quirinalis, who superintended the rights of Quirinus or Romulus; but the number was ultimately increased to fifteen, the original three, however, retaining priority in point of rank, being styled Majores, and elected from among the patricians, while the other twelve, called Minores, were elected from the plebeians.

Caius Julius (more popular known as Julius Caesar or Caesar) was a great Roman general, statesman, and historian. He was born in 100 BC and died in 44. He was the son of the praetor Caius Julius Caesar, and of Aurelia, a daughter of Aurelius Cotta. At the age of sixteen he lost his father, and shortly after he married Cornelia, the daughter of Lucius Cinna, the friend of Marius. This connection gave great offence to Sulla, the dictator, who proscribed him for refusing to put away his wife. His friends obtained his pardon with difficulty, and Caesar withdrew from Rome, and went to Asia, serving his first campaign under M. Minucius Thermus, the praetor in Asia.
On the death of Sulla, Caesar returned to Rome, where he distinguished himself as an orator. He afterwards visited Rhodes, when he was taken by pirates, and compelled to pay fifty talents for his release. To revenge himself, he fitted out some vessels at Miletus, overtook the pirates, made the greater number of them prisoners, and had them crucified before Pergamus. He now returned to Rome, where his eloquence and liberality made him very popular. He was pontifex maximus in 63 BC, praetor in 62 BC, and governor of Spain in 61 BC.
On his return to Rome, having united with Pompey and Marcus Crassus in the memorable coalition called 'the first triumvirate,' he became consul, and then obtained the government of Gaul with the command of four legions.
His military career was rapid and brilliant. He compelled the Helvetii, who had invaded Gaul, to retreat to their native country, subdued Ariovistus, who at the head of a German tribe had attempted to settle in the country of the AEdui, and conquered the Belgae. In nine years he reduced all Gaul, crossed the Rhine twice (in 55 BC and 53 BC), and twice passed over to Britain, defeated the gallant natives of this island in several battles, and compelled them to give him hostages.
The senate had continued his government in Gaul for another period of five years, while Pompey was to have the command of Spain, and Marcus Crassus that of Syria, Egypt, and Macedonia for five years also. But the death of Marcus Crassus in his campaign against the Parthians dissolved the triumvirate; and about the same time the friendship between Caesar and Pompey cooled. The senate, influenced by Pompey, ordered that Caesar should resign his offices and command within a certain time, or be proclaimed an enemy to the state, and appointed Pompey general of the army of the Republic. Upon this Csesar urged his soldiers to defend the honour of their leader, passed the Rubicon (in 49 BC), and made himself master of Italy without striking a blow, Pompey retiring into Greece. Caesar then levied an army with the treasures of the state, and hastened into Spain, which he reduced to submission without coming to a pitched battle with Pompey's generals.
He next conquered Massilia (now Marseilles), and returned to Rome, where he was appointed dictator. He then followed Pompey into Greece, and defeated him at Pharsalia, from which Pompey escaped only to be assassinated in Egypt. In Rome the senate and the people strove eagerly to gain the favour of the victor. They appointed him consul for five years, dictator for a year, and tribune of the people for life. When his dictatorship had expired he caused himself to be chosen consul again, and without changing the ancient forms of government, ruled with almost unlimited power. In 46 BC he crossed to Africa, defeated the Pompeians Scipio and Cato at Thapsus, and returning to Rome he was received with the most striking marks of honour. The term of his dictatorship was prolonged to ten years, the office of censor conferred on him alone; his person was declared inviolable, and his statue placed beside that of Jupiter in the capitol.
He soon after was honoured with four several triumphs, made perpetual dictator, and received the title of imperator with full powers of sovereignty. In February, 44, he declined the diadem which Antony publicly offered him, and next morning his statues were decked with diadems. His glory, however, was short lived, for a conspiracy was set on foot by his enemy Cassius, and joined by many of his own friends, including M. Brutus; and, notwithstanding dark hints had been given to him of his danger, he attended a meeting of the senate on 15th (ides) March, 44 BC, and fell beneath the daggers of the conspirators.
Of his writings, we still possess the history of his wars with the Gauls and with Pompey. Caesar was undoubtedly the foremost man of all this world, being great as a statesman, a general, an orator, a historian, and an architect and engineer, and his assassination was brought about more by jealousy and envy than by real patriotism.
