Alchemy or alchymy is the art which in former times occupied the place of and paved the way for the modern science of chemistry (as astrology did for astronomy), but whose aims were not scientific, being confined solely to the discovery of the means of indefinitely prolonging human life, and of transmuting the baser metals into gold and silver.
Among the alchemists it was generally thought necessary to find a substance which, containing the original principle of all matter, should possess the power of dissolving all substances into their elements. This general solvent, or menstruum universale, which at the same time was to possess the power of removing all the seeds of disease out of the human body and renewing life, was called the philosophers stone, lapis philosopherum, and its pretended possessors were known as adepts. Alchemy nourished chiefly in the middle ages, though how old might be such notions as those by which the alchemists were inspired it is difficult to say. The mythical Hermes Trismegistus of pre-Christian times was said to have left behind him many books of magical and alchemical learning, and after him alchemy received the name of the hermetic art.
At a later period chemistry and alchemy were cultivated among the Arabians, and by them the pursuit was introduced into Europe. Many of the monks devoted themselves to alchemy, although they were latterly prohibited from studying it by the popes. But there was one even among these, John XXII, who was fond of alchemy. Raymond Lully, or Lullius, a famous alchemist of the thirteenth and fourteenth centuries, is said to have changed for King Edward I a mass of 50,000 lbs of quicksilver (mercury) into gold, of which the first rose-nobles were coined.
Among other alchemists may be mentioned Paracelsus and Basilius Valentinus. With the growth of chemistry, the recognition of the chemical elements as forming a large number of distinct substances, and the conception of the fixed unalterable nature of the atoms, attempts to transform the base metals into gold were largely abandoned as being unscientific.

An almanac is a calendar, in which are set down the rising and setting of the sun, the phases of the moon, the most remarkable positions and phenomena of the heavenly bodies, for every month and day of the year; also the several fasts and feasts to be observed in the church and state, etc, and often much miscellaneous information likely to be useful to the public.
The term is of Arabic origin, but the Arabs were not the first to use almanacs, which indeed existed from remote ages. In England they are known from the fourteenth century, there being several English almanacs of this century existing in manuscript form. They became generally used in Europe within a short time after the invention of printing; and they were very early remarkable, as some are still, for the mixture of truth and falsehood which they contained. Their effects in France were found so mischievous, from the pretended prophecies which they published, that an edict was promulgated by Henry III in 1579 forbidding any predictions to be inserted in them relating to civil affairs, whether those of the state or of private persons.
In the reign of James I of England letters-patent were granted to the two universities and the Stationers' Company for an exclusive right of printing almanacs, but in 1775 this monopoly was abolished. During the English Civil War, and thence onward, English almanacs were conspicuous for the unblushing boldness of their astrological predictions, and their determined perpetuation of popular errors. The most famous English almanac was Poor Robin's Almanac, which was published from 1663 to 1775.
Gradually, however, a better taste began to prevail, and in 1828 the Society for the Diffusion of Useful Knowledge, by publishing the British Almanac, had the merit of taking the lead in the production of an unexceptionable almanac in Great Britain. The example thus set has been almost universally adopted. The circulation of almanacs continued to be much cramped by the very heavy duty of one shilling and threepence per copy until 1834, when this duty was abolished. About 200 new almanacs were started immediately on the repeal.
Almanacs, from their periodical character, and the frequency with which they are referred to, are now more and more used as vehicles for conveying statistical and other useful information, some being intended for the inhabitants of a particular country or district, others for a particular class or party. Some of the almanacs that are regularly published every year are extremely useful, and before the Internet and improved communications were almost indispensable to men engaged in official, mercantile, literary, and professional business. Such in Great Britain were Thorn's Official Directory of the United Kingdom, the British Almanac, Oliver and Boyd's Edinburgh Almanac, and Whitaker's Almanac, now so well known.
In the United States was published The American Almanac, a useful compilation. The Almanach de Gotha, which first appeared at Gotha in 1764, contained in small bulk a wonderful quantity of information regarding the reigning families and governments, the finances, commerce, population, etc, of the different states throughout the world. It was published both in a French and in a German edition. Almanacs that pretend to foretell the weather and occurrences of various kinds are still popular in Britain, France, and elsewhere.
The Nautical Almanack was an important work published annually by the British government, two or three years in advance, in which was contained much useful astronomical matter, more especially the distances of the moon from the sun, and from certain fixed stars, for every three hours of apparent time, adapted to the meridian of the Royal Observatory, Greenwich. By comparing these with the distances carefully observed at sea the mariner could with comparative ease, infer his longitude to a degree of accuracy unattainable in the past by any other way, and sufficient in the past for most nautical purposes. This almanac was commenced in 1767 by Dr. Maskelyne, astronomer royal. The French Connaissance des Temps was published with the same views as the English Nautical Almanac, and nearly on the same plan. It commenced in 1679. Of a similar character was the Astronomisches Jahrbuch formerly published at Berlin. Research Almanac
The American Civil Rights Act was an act passed by Congress over President Johnson's veto on April the 9th 1866, aiming to place the Negro on the same civil footing as the whites. Its principal section provided that all persons born in the United States, and not subjected to any foreign power, excluding Indians not taxed, were to be recognized as citizens of the United States. The violation of this act was made a misdemeanour to be considered by the Federal courts alone. The President was given power to enforce the act by special or military force. The controversy over the constitutionality of the act led to the framing of the Fourteenth Amendment, passed June the 13th, 1866. After this a more stringent act to secure the civil rights of the Negro was passed in 1875. But the Supreme Court in 1883 declared its most important sections unconstitutional.

The Grand Army of the Republic was an American organisation for former members of the Armed forces, organized during the winter of 1865-66 at Springfield, Illinois, chiefly through the activity of Dr. B. F. Stephenson, late surgeon of the FourteenthIllinois Infantry. The first post was established at Decatur, Illinois, in 1866. The ritual is secret. All soldiers and sailors of the US army, navy and marine corps between April 12, 1861, and April 9, 1865, were eligible for membership, provided they had an honourable discharge. National conventions were held each year. The first commander-in-chief was Stephen A. Hurlbut, of Illinois. Grand army posts were established in nearly every city in the North and West. The last National Encampment was held at Indianapolis, Indiana in 1949. Six surviving Comrades attended that Encampment. The last member of the Grand Army of the Republic, Albert Wollson, died in 1956. Research Grand Army of the Republic
Madoc or Madog, was a legendary Welsh prince, a son of Owain Gwynedd, who is said, in accordance with a tradition first published in the sixteenth century, to have sailed west about 1171 and discovered America. The first mention of this Madog is in a Welsh poem of the fourteenth century. The legend is highly dubious. Research Madoc

The Renaissance was that change in the outlook of Europe which took place during the centuries from the fourteenth to the sixteenth. In its broadest sense the Renaissance affected every department of human life. But in its narrower sense it refers to the revival of the learning of ancient Greece, and to the effects of that revival on the arts and literature of modern peoples. The Church in the Middle Ages had taught men to revere authority and to find in her teaching an answer to all the problems of life, whereas the Greeks taught men to inquire and to explore rather than to accept, and to enjoy rather than to suffer. It was this attitude of mind, more than anything else, which shook the medieval world to its foundations. The views of the ancient Greeks, now re-born into the world, were in sharp contrast with the ideals of the Middle Ages. From these ideals many men for a time turned with a feeling of contempt.
The Renaissance was a many-sided movement: it deeply influenced learning and education, art and architecture, science and invention, geography and exploration, and, above all, religion. After the fall of Rome, a knowledge of Greek had rapidly died out in the West and no provision was made for its teaching similar to that made for Latin. In Italy, owing to the closeness of its relations with the East, the number of scholars, monks, and others, who learnt some Greek was greater than elsewhere. It is not, surprising, therefore, that the revival of learning received its main impulse from Italy. From the time of Petrarch and Boccaccio, Italian scholars became more and more devoted to ancient studies, and they began to visit Constantinople, where Greek learning had been preserved. There they hunted out, copied, and eagerly studied the precious manuscripts of the past, and these opened up a new world of thought. Further, from the time that the Turks' crossed from Asia into Europe, some of the Greeks themselves began to travel westwards and to accept well-paid teaching posts in the wealthy Italian cities. And, though the revival began in Italy, the new ideas were rapidly circulated by the new printing presses invented at the time, and every nation in due course played its part in the Renaissance.
The great and wealthy city of Florence was the centre of the Italian Renaissance. Cosimo de Medici, a merchant prince who became ruler of the city, was a patron of the New Learning, and he encouraged Greek scholars to settle in Florence. His grandson, Lorenzo de Medici, known as The Magnificent, loved to gather round him the learned men of the day; he spent 60,000 pounds a year on books; and he caused 200 rare manuscripts to be brought from the East to the Medici library. Rome was second only to Florence as a centre of the New Learning. The Popes themselves became great patrons of learning. Nicholas V founded the Vatican Library. When the son of Lorenzo de Medici became Pope as Leo X, the Renaissance in Rome reached its highest point. Leo made Rome, as he said, ' the capital of the world in literature, as it is in everything else'. He provided a hundred professors for his Greek college in Rome, and he brought his father's library to the Holy City. The library was afterwards restored to Florence by his cousin Clement VII, another member of this remarkable Medici family. The New Learning influenced England from the time of Edward IV, and it made great headway in the reigns of Henry VII and Henry VIII when the scholars known as the Oxford Reformers were flourishing.
The first Englishman to bring Greek manuscripts to England was William Selling. One of his pupils was Thomas Linacre, who went to Florence and shared the instruction given to the young Medici princes; he read in the Vatican Library, and made the acquaintance of Aldo at Venice. Another Oxford teacher who drew his inspiration from Italian sources was William Grocyn, one of the first men to give lectures on Greek literature at his University.
One of Grocyn's pupils was John Colet, who visited Italy in 1496 and returned to lecture on the Gospels in the Greek original at Oxford. He and Sir Thomas More, were friends of Erasmus, a Dutch scholar of international fame. Lady Margaret Beaufort, mother of Henry VII, was herself a patroness of the New Learning. She founded two Cambridge colleges, Christ's and St. John's, and two Lady Margaret Professorships of Divinity, one at Oxford and one at Cambridge. The Revival of Learning was one aspect of the Renaissance; the outburst of artistic energy in the fifteenth and sixteenth centuries was another. The painters of the new period broke away from the conventional art of the Middle Ages and began again to draw from living models. As with the artists, so with the sculptors. Donatello 'went straight with his mighty chisel to original sources - to youth and manhood, and the love of living'. The great figures of that age - Botticelli, Leonardo da Vinci, Michelangelo, Raphael, Titian - still dominate the history of European art. Examples of their works, and of many other Italian artists of the Renaissance, as well as of the Northern artists - Holbein, Durer, and others - are to be seen in the magnificent collection at the National Gallery.
It was natural that men who sought their inspiration from the Greeks should turn with renewed interest to classical architecture. The ruins of ancient Rome provided examples ready to hand; and soon churches planned like classical temples were rising in every city in Italy. St. Peter's, Rome, was designed by Bramante, and the famous dome added by Michelangelo. But great as was the enthusiasm for this architecture Renaissance architecture did not establish itself in England until the end of the reign of Queen Elizabeth I, though Henry VII's tomb at WestminsterAbbey is an example of the Florentine art of the period.
The Renaissance period, filled as it was with a love of experiment, naturally produced a renewed interest in science. With the exception of isolated geniuses like Friar Roger Bacon, there were no medieval scientists worthy of the name. Practically no scientific discoveries had been made for centuries. Modern Science begins its history with the Renaissance and owes a good deal to Leonardo da Vinci. He was the first of a long line of experimenters whose work has continued to the present day. The greatest shock to the medieval notions of the universe was given by Copernicus. For two thousand years mankind with few exceptions had believed that the earth was the centre of the universe, and that the sun revolved round our planet every twenty-four hours. Such had been the teaching of Ptolemy, the Greek scientist. Another Greek, Pythagoras, had questioned it, and advanced the extraordinary notion that the sun, not the earth, was the centre of the universe; but there were few who accepted his theory until Copernicus turned his attention to the 'solar system'. Through slits cut in the walls of his house, Copernicus watched the movements of the planets. Just before he died in 1543 he published a book - 'The Revolutions of the Heavenly Bodies' - giving to the world the results of his observations.
Twenty years later the famous Galileo was born at Pisa, and it was he who perfected the telescope. He lived to popularise the theory of Copernicus, but he was nearly put to death for his pains and was forced by the Court of Inquisition to recant. The Italian Galileo, and the English Newton who discovered the laws of gravity, were the two greatest scientists of the seventeenth century. In the realm of geographical discovery, no age in the world' s history was more momentous than the Age of the Renaissance. Columbus, who discovered America; Vasco De Gama, who found the Cape Route to India; Cabot, Cartier, and Cortez, the discoverers of Newfoundland, Canada, and Mexico; Balboa, who first sailed on the Pacific; Magellan, whose ship was the first to sail round the world - all these and many more make the fifteenth and sixteenth centuries an era without parallel in the annals of discovery.
The new ideas which came surging into the world during the Renaissance acted in many respects as disruptive forces. This was particularly true in the realm of religion. An unquestioning acceptance of authority - i.e. of the teaching of the Catholic Church - was the keynote of the medieval attitude to life, but an eager, inquiring generation began to question this attitude. Men, too, were shocked by the moral decay of the Church and of the Papacy; voices were raised demanding reforms. Some reformers, like Colet and Erasmus, tried to reconcile the new ideas with the Church of Rome and worked to reform it; others, of whom Luther was the greatest, rejected altogether its authority.
The revolution in European history known as the Reformation was an indirect result of the Renaissance - of the New Learning which invited comparison between the present and the past; of the invention of printing which scattered broadcast the new ideas; and again, of the growing idea of the Nation and with it the supremacy of the State.

Aristotle was an ancient Greek philosopher and naturalist. He was born in 384 BC at Stagira, in Macedonia, died in 322 BC.. He was the founder of the Peripatetic school of philosophy, His father, Nicomachus, was physician to Amyntas II, king of Macedonia, and claimed to be descended from Aesculapius. Aristotle had lost his parents before he came, at about the age of seventeen, to Athens to study in the school of Plato. With that philosopher he remained for twenty years, became pre-eminent among his pupils, and was known as the Intellect of the School. Upon the death of Plato in 848 BC, he took up his residence at Atarneus, in Mysia, on the invitation of his former pupil Hermeias, the ruler of that city, on whose assassination by the Persians in 343 BC, he fled to Mitylene with his wife Pythia, the niece of Hermeias.
During his residence at Mitylene he received an invitation from Philip of Macedon to superintend the education of his son Alexander, then in his fourteenth year. This relationship between the great philosopher and the future conqueror continued for five or six years, during which the prince was instructed in grammar, rhetoric, poetry, logic, ethics, and politics, and in those branches of physics which had even then made some considerable progress. On Alexander succeeding to the throne Aristotle continued to live with him as his friend and councillor until he set out on his Asiatic campaign in 334 BC. He returned to Athens and established his school in the Lyceum, a gymnasium attached to the temple of Apollo Lyceius, which was assigned to him by the state. He delivered his lectures in the wooded walks of the Lyceum while walking up and down with his pupils. From the action itself, or more probably from the name of the walks (peripatoi), his school was called Peripatetic. Pupils gathered to him from all parts of Greece, and his school became by far the most popular in Athens. The statement that he had two circles of pupils, the exoteric and the esoteric has given rise to much controversy.
By some it has been held that Aristotle published during his lifetime popular discourses with a view to make way for his doctrines in Athenian society, then impregnated with Platonic theories, and that these are called exoteric in contradistinction to those in which are embodied his matured opinions. It was during the time of his teaching at Athens that Aristotle is believed to have composed the great bulk of his works. On the death of Alexander a revolution occurred in Athenshostile to the Macedonian interests with which Aristotle was identified. He therefore retired to Chalcis, where he soon after died.
According to Strabo he bequeathed all his works to Theophrastus, who, with other disciples of Aristotle, amended and continued them. They afterwards passed through various hands, until, about 50 BC, Andronicus of Rhodes put the various fragments together and classified them according to a systematic arrangement. Many of the books bearing his name are spurious, others are of doubtful genuineness. The whole are generally divided into logical, theoretical, and practical. The logical works are comprehended under the title Organon (instrument). The theoretical are divided into physics, mathematics, and metaphysics. The physical works (including those on natural history) are on the General Principles of Physical Science, The Heavens, Generation and Destruction, Meteorology, Natural History of Animals, On the Parts of Animals, On the Generation of Animals, On the Locomotion of Animals, On the Soul, On Memory, Sleep and Waking, Dreams, Divination. In mathematics there are two treatises, On Indivisible Lines and Mechanical Problems. The Metaphysics consist of fourteen books: the title (Tametata Physika, 'the things following the Physics') is the invention of an editor. The practical works embrace ethics, politics, economics, and treatises on art, and comprise the Nicomachaean Ethics (so called because dedicated to his son Nicomachus), the Politics, (Economics, Poetry, and Rhetoric). Among the lost works are the dialogues and others to which the term exoteric is applied, and which were published during Aristotle's lifetime. His style is devoid of grace and elegance. His works were first printed in a Latin translation, with the commentaries of Averroes, at Venice in 1489; the first Greek edition was that of Aldus Manutius (published in five volules between 1495 and 1498).
