An altar is a pile or structure raised above the ground for receiving sacrifices to some divinity. The Greek and Roman altars were various in form, and often highly ornamental; in temples they were usually placed before the statue of the god. In the Jewish ceremonial the altar held an important place, and was associated with many of the most significant rites of religion. Two altars were erected in the tabernacle in the wilderness, and the same number in the temple, according to instructions given to Moses in MountSinai. These were called the altar of burnt-offering and the altar of incense. In some sections of the Christian church the communion-table, or table on which the eucharist is placed, is called an altar. In the primitive church it was a table of wood, but subsequently stone and metal were introduced with rich ornaments, sculpture, and painting. After the introduction of Gothic art the altar frequently became a lofty and most elaborate structure. Originally there was but one altar in a church, but latterly there might be several in a large church, the chief or high altar standing at the east end. Over an altar there is often a painting (an altar-piece), and behind it there may be an ornamental altar-screen separating the choir from the east end of the church. Lights are often placed on or near the altar. Research Altar
The Athenaeum was the temple of Athena or Minerva, at Athens. It was frequented by poets, learned men, and orators. The same name was given at Rome to the school which Hadrian established on the Capitoline Mount for the promotion of literary and scientific studies. In modern times the same name is given to literary clubs and establishments connected with the sciences. Research Athenaeum
Babism is the doctrines of a Muslim messianic Shiite sect. Founded in 1844 by the Persian Sayyid Ali Muhammad of Shiraz known as the Bab ed-Din (the gate or intermediary between man and God), who declared himself to be the long-awaited Mahdi. For inciting insurrection the Bab was arrested in 1848 by the government and executed in 1850, his remains being interred in 1909 on MountCarmel, Palestine. In 1863 Baha'ullah and his son Abdul Baha declared themselves the new leaders, and their followers became known as the Baha'is. Research Babism
The coconut cup was a drinking vessel first seen in Britain around the 13th century, and used by the rich who preferred them to the more 'common' mazer-bowl. Coconut cups were made from a coconut shell, mounted on a Gothicsilvermount and mounted with silver at the rim. Similar vessels were also made from ostrich eggs (then called griffin's eggs).

Genre painting is a type of painting concerned with the realistic depiction of scenes from everyday life. Originally the term was applied to all paintings that were factual representations of nature (animals, fruit, and landscapes), as well as scenes of ordinary life, rather than to works of imagination, such as religious and historical paintings. Genre paintings deal with ordinary life, including family life, sports, street scenes, picnics, festivals, and tavern scenes. They are usually characterised by human interest and by the care and finish with which they are executed.
Genre painting originated in ancient times. Many of the scenes painted on the walls of Egyptian tombs represent the daily life of the people of ancient Egypt. Excavations in the ancient cities of Pompeii and Herculaneum have revealed many genre paintings, both conventional and erotic. In the late Middle Ages genre painting reappeared, represented chiefly in the religious calendars that formed part of the illuminations, or illustrations, of manuscript books; the calendars show people going about the occupations appropriate to each season of the year.
In Italy during the early Renaissance, many of the religious and historical pictures of such painters as the 15th-century Florentines Ghirlandaio and Benozzo Gozzoli and the later Venetians Giorgione and the Bassano family are considered genre paintings because of their contemporaneous backgrounds and costumes as well as their use of people of the times as models. In 17th- century Italy, Mannerist painters such as Caravaggio executed genre paintings of extreme realism and dramatic power. In the 15th century the Flemish painter Petrus Christus in some of his religious paintings represented scenes from ordinary life, and in the following two centuries genre painting rose to its highest level in history with the work of the Flemish artists Pieter Brueghel the Elder, David Teniers, and Adriaen Brouwer. The greatest national school of genre painting was that of the Netherlands in the 17th century. Probably never before or after was the ordinary life of a nation depicted so fully as was the Dutch life of this period. Not only the great masters but also the less outstanding Dutch painters excelled in it.
The most important of the Dutch genre painters were the so-called little masters, including Gerard Ter Borch, Jan Steen, Gabriel Metsu, Pieter de Hooch, Gerard Dou, and Adrian Van Ostade. The three leading 17th-century Dutch masters, Rembrandt, Frans Hals, and Jan Vermeer, also created genre paintings of unrivalled beauty. French genre painting showed a vital development in the work of Antoine Watteau, Nicolas Lancret, Jean Baptiste Chardin, and Jean Honore Fragonard. One of the most noted English genre painters was the great satirist William Hogarth. In the 19th century, genre painting was widely practised in both Europe and the USA Among the outstanding European painters in this style were the French painters Jean Leon Gerome and Jean Meissonier, the English painter William Powell Frith, and the American painter William Sidney Mount, known as the 'JanSteen of Long Island.' Among the many 19th- and 20th- century American painters whose work included genre painting were Robert Henri, John Sloan, George Wesley Bellows, George B Luks, Charles E Burchfield, Reginald Marsh, Grant Wood, and Thomas Hart Benton.

In geography, a geyser (from the Icelandic geysir which in turn deribes from heysa meaning to gush or rush forth) is a term applied to natural springs of hot water of the kind that were first observed in Iceland. The geysers of Iceland, about a hundred in number, lie about 30 miles north west of Mount Hecia, in a plain covered by hot-springs and steaming apertures. The two most remarkable are the Great Geyser and the New Geyser or Strokkur (churn), the former of which throws up at times a column of hot water to the height of from 80 to 200 feet. The basin of the Great Geyser is about 70 feet across at its greatest diameter. The New Geyser, which is only 100 meters away, is much smaller in size. The springs are supposed to be connected with Mount Hecia, and the phenomenon of eruption has been explained by Tyndall as due to the heating of the walls of a fissure, whereby the water is slowly raised to the boiling point under pressure, and explodes into steam, an interval being required for the process to be repeated. The geysers of Iceland, however, were surpassed by those discovered in the Rocky Mountains in the Yellowstone Region of Wyoming Territory, the largest of which throw up jets of water from 90 to 250 feet high. The hot-lake district of Auckland, New Zealand, is also famous in possessing some of the most remarkable geyser scenery in the world. These phenomena are of three kinds: the puias (fire-springs), geysers continually or intermittently active; ngawhas or inactive puias, which emitsteam, but do not throw up columns of water; and waiariki or hot-water cisterns. This region is remarkable for the number of natural terraces containing hot-water pools or cisterns, and its lakes all filled at intervals by the boiling geysers and thermal springs, but the configuration of the country was considerably altered by the disastrous volcanic outbreak of 1886. Ngahapu or Ohopia, a circular rocky basin, 40 feet in diameter, in which a violent geyser is constantly ng up to the height of 10 or 12 feet, emitting dense clouds of steam, is one of the natural wonders of the southern hemisphere.

Mountains are often classified according to their mode of formation: Fold
mountains; Block mountains; Residual mountains; Volcanic mountains.
High mountain chains such as the Himalayas, Andes, Alps, and Rockies are known as new fold mountain systems. The term 'fold' is a reference to the way in which such mountains have been formed. Throughout millions of years slow movements of the earth's crust have caused these
mountains to be raised. The movements which have resulted in mountain buildings were not, however, vertical uplifts. They were primarily horizontal movements, the effect of which was to cause the crust of the earth to 'wrinkle', in a similar way to which a tablecloth wrinkles if it is pushed along the table. The arched or upraised parts of the folds are known as anticlines and the troughs as synclines. These folds can vary greatly in size. Mountain building is undoubtedly due to some deep-seated cause. For a long period the most simple explanation was that folding was entirely due to the cooling and contraction of the earth, so that the crust, already cold and shrunken, had to wrinkle to fit itself to the still cooling and contracting 'core'. One of the objections advanced against this theory is that the amount of shrinking necessary to account for the Himalayas, Alps, etc., seems to be greater than the mere contraction of the earth would allow. While the theory of contraction cannot be completely rejected, serious consideration must be given to the more recent explanations of mountain building. For instance, Wegener suggests that mountain building may be due to the 'wrinkles' produced by the drifting of a continental mass, e.g. that the Alps were formed by the northward drift of the African continent towards the more stable blocks of Central Europe. As the African mass drifted slowly northward the zone between it and the European mass became narrower, and the land was raised into high ridges or folds. The raising of the Alps was accompanied by the formation of the deep trough which contains the Mediterranean Sea. The same hypothesis would account for the building of the Himalayas and the depression of the Indo-Gangetic trough by the northward drift of the Deccan mass.
During the physical history of the earth, mountain building appears to have proceeded more actively at some periods than others. Fold mountains are, therefore, not all of the same age. The newest group of fold mountains include the Himalayas, Alps, Rockies, and Andes. During an earlier period of folding (the Carboniferous) the Pennines, Appalachians, the Cape Ranges of South Africa, and the Dividing Range of Australia were uplifted. A still earlier period of folding accounted for the original mountains of Scotland and Norway, of which the present mountains are merely the worn down stumps. The older fold mountains, which have been subjected to the forces of denudation (such as the weather, rivers, glaciers, etc.) for long geological periods, are much lower and less rugged than the newer fold mountains. The term 'new fold' is applied to the mountain ranges which have been folded most recently, but they seem very old when their age in actual years is considered because they were uplifted many millions of years before historic time. Mountain building is a very long and slow process; and in the case of certain mountain chains, such as the Andes and the mountains of Japan, is probably still proceeding.
The new fold mountain systems of the world, except in such instances as the simple low folds of the Weald (South-east England), usually consist of high parallel ranges, the average height being well over 3000 metres. In the Himalayas' the highest peak rises to 8840 metres; in the Andes 7000 metres; in the Rockies 6000 metres; in the Alps to 4600 metres. Vast though these heights appear, the wrinkles of the earth's crust are only slight. The highest mountain in the world (MountEverest) is about five miles high, so that on a globe of 40 cm, diameter it would protrude only 2.5 mm. Most of the active volcanoes are found in the neighbourhood of fold mountains, where the crust of the earth has been fractured during the process of folding. All around the PacificOcean there are many active and extinct volcanoes, as in New Zealand, the East Indies, Japan, and North, Central, and South America. Another belt of active volcanoes is associated with the fold mountains of the West Indies. The mountains of this type are characterised by ruggedness of relief in contrast to the smooth and rounded contours of mountain areas which have been subjected to weathering agents for long periods of time. This is obvious if pictures of the Alps and the Scottish Highlands are compared.
Mountains are effective climatic barriers, and the climates of regions on either side of a high mountain range are very different. For example, the coast lands of British Columbia have an equable climate and a heavy rainfall, while the lands to the east of the Rockies have an extreme climate and light rainfall. Again, the climate of the mountainous areas differs from that of the adjacent lowlands. The great mountain systems of the world are mainly important for their minerals, and, in the temperate zone, for their lumber. In the plateau regions of some mountain systems agriculture has been made possible by irrigation, and above the forests in temperate areas there are valuable alpine pastures. The swift streams of mountains are frequently sources of hydro-electric power, especially in countries which have no coal, such as Switzerland and Norway. In North America, the Western Cordillera provides gold, copper, lead, and silver, especially in the states of Nevada and Montana. The Andes provide tin and copper (Bolivia), gold and platinum
(Colombia), and silver (Peru). The Highlands of East Australia are important for copper and gold. The lumbering industry is specially important in British Columbia, Washington, and Oregon (soft woods), the Central American mountainous lands (hard woods), the Himalayan slopes (teak and sal), and the Scandinavian mountains (soft woods).
To provide food for the mining communities in inaccessible mountain areas, agriculture has been developed. There are numerous irrigation schemes in operation in most of the mountain states of the USA, e.g. at SaltLake City in Utah. Similarly, the Andean states, e.g. Bolivia, grow small quantities of cereals in the plateau areas. Mountain pastures have been utilised most extensively for cattle rearing in Switzerland and Scandinavia. The vast central plateau of Asia is, owing to difficulty of access and climatic extremes, so isolated from other regions that very little development of any kind, on modern lines, has taken place. High mountain ranges are also barriers to communication, and so tend to separate peoples. Traffic across mountains is limited to the passes, which are often so high as to be snowbound in winter. Such ranges as the Alps, Andes, etc. can only be crossed with great difficulty or by expensive tunnelling.
It sometimes happens that movement of the earth's crust occurs along cracks or faults. Where such movement leaves a block of higher land standing between two areas of lower land, the highland is known as a 'Block Mountain' or horst. The Vosges and Black Forest Mountains are examples of such formations These mountains are usually very steep-sided, and often the summit levels are roughly the same.
When an area of highland remains standing above the general level after rivers and other natural agents have lowered the surface of the surrounding area, the name residual mountain is used. Sometimes such highlands are called 'mountains of denudation'. This term can usually be applied to the mountain ridges associated with 'dissected plateaux'. Included in this class are the mountain ridges of the Highlands of Scotland, the Sierras of Central Spain, and the Mesas and Buttes of the western plateaulands of the United States.
Mountains may be formed by volcanic material piled up around a crater, such mountains are popularly known as volcanoes. Research Mountains
