Chapter IX: Part 9

CARACAS, the principal city and the capital of the United States of Venezuela, situated at the western extremity of an elevated valley of the Venezuelan Coast Range known as the plain of Chacao, 6-1/2 m. S.S.E. of La Guaira, its port on the Caribbean coast, in lat. 10 deg. 30' N., long. 67 deg. 4' W. The plain is about 11 m. long by 3 m. wide, and is separated from the coast by a part of the mountain chain which extends along almost the entire water front of the republic. It is covered with well-cultivated plantations. The Guaira river, a branch of the Tuy, traverses the plain from west to east, and flows past the city on the south. Among its many small tributaries are the Catuche, Caroata and Anauco, which flow down through the city from the north and give it a natural surface drainage. The city is built at the narrow end of the valley and at the foot of the Cerro de Avila, and stands from 2887 to 3442 ft. above sea level, the elevation of the Plaza de Bolivar, its topographical centre, being 3025 ft. Two miles north-east is the famous Silla de Caracas, whose twin summits, like a gigantic old-fashioned saddle (_silla_), rise to an elevation of 8622 ft.; and the Naiguete, still farther eastward, overlooks the valley from a height of 9186 ft. The climate of Caracas is often described as that of perpetual spring. It is subject, however, to extreme and rapid variations in temperature, to alternations of dry and humid winds (the latter, called _catias_, being irritating and oppressive), to chilling night mists brought up from the coast by the westerly winds, and to other influences productive of malaria, catarrh, fevers, bilious disorders and rheumatism. The maximum and minimum temperatures range from 84 deg. to 48 deg. F., the annual mean being about 66 deg., and the daily variation is often as much as 15 deg. The city is built with its streets running between the cardinal points of the compass and crossing each other at right angles. Two intersecting central streets also divide the city into four sections, in each of which the streets are methodically named and numbered, as North 3rd, 5th, 7th, &c., or West 2nd, 4th, 6th, &c., according to direction and location. This method of numeration dates from the time of Guzman Blanco, but the common people adhere to the names bestowed upon the city squares in earlier times. The streets are narrow, but are clean and well-paved, and are lighted by electricity and gas. There are several handsome squares and public gardens, adorned with statues, trees and shrubbery. The principal square is the Plaza de Bolivar, the conventional centre of the city, in which stands a bronze equestrian statue of Bolivar, and on which face the cathedral, archbishop's residence, Casa Amarilla, national library, general post office and other public offices. The Independencia Park, formerly called Calvario Park, which occupies a hill on the west side of the city, is the largest and most attractive of the public gardens. Among the public edifices are the capitol, which occupies a whole square, the university, of nearly equal size, the cathedral, pantheon, masonic temple (built by the state in the spendthrift days of Guzman Blanco), national library, opera-house, and a number of large churches. The city is generously provided with all the modern public services, including two street car lines, local and long distance telephone lines, electric power and light, and waterworks. The principal water supply is derived from the Macarao river, 15 m. distant. Railway connexion with the port of La Guaira was opened in 1883 by means of a line 23 m. long. Another line (the Gran Ferrocarril de Venezuela) passes through the mountains to Valencia, 111 m. distant, and two short lines run to neighbouring villages, one to Petare and Santa Lucia, and the other to El Valle. The archbishop of Venezuela resides in Caracas and has ecclesiastical jurisdiction over the dioceses of Ciudad Bolivar, Calabozo, Barquisimeto, Merida and Maracaibo. There are no manufactures of note.

Caracas was founded in 1567 by Diego de Losada under the pious title of Santiago de Leon de Caracas, and has been successively capital of the province of Caracas, of the captaincy-general of Caracas and Venezuela, and of the republic of Venezuela. It is also one of the two chief cities, or capitals, of the Federal district. It was the birthplace of Simon Bolivar, and claims the distinction of being the first colony in South America to overthrow Spanish colonial authority. The city was almost totally destroyed by the great earthquake of 1812. In the war of independence it was repeatedly subjected to pillage and slaughter by both parties in the strife, and did not recover its losses for many years. In 1810 its population was estimated at 50,000; seventy-one years later the census of 1881 gave it only 55,638. In 1891 its urban population was computed to be 72,429, which in 1904 was estimated to have increased to about 90,000.

CARACCI, LODOVICO, AGOSTINO, and ANNIBALE, three celebrated Italian painters, were born at Bologna in 1555, 1557, and 1560 respectively. Lodovico, the eldest, son of a butcher, was uncle to the two younger, Agostino and Annibale, sons of a tailor, and had nearly finished his professional studies before the others had begun their education. From being a reputed dunce, while studying under Tintoretto in Venice, he gradually rose, by an attentive observation of nature and a careful examination of the works of the great masters preserved at Bologna, Venice, Florence and Parma, to measure himself with the teachers of his day, and ultimately projected the opening of a rival school in his native place. Finding himself unable to accomplish his design without assistance, he sent for his two nephews, and induced them to abandon their handicrafts (Agostino being a goldsmith, and Annibale a tailor) for the profession of painting. Agostino he first placed under the care of Fontana, retaining Annibale in his own studio; but he afterwards sent both to Venice and Parma to copy the works of Titian, Tintoretto and Correggio, on which his own taste had been formed. On their return, the three relatives, assisted by an eminent anatomist, Anthony de la Tour, opened, in 1589, an academy of painting under the name of the Incamminati (or, as we might paraphrase it, the Right Road), provided with numerous casts, books and bassi-rilievi, which Lodovico had collected in his travels. From the affability and kindness of the Caracci, and their zeal for the scientific education of the students, their academy rose rapidly in popular estimation, and soon every other school of art in Bologna was deserted and closed. They continued together till, at the invitation of Cardinal Farnese, Annibale and Agostino went to Rome in 1600 to paint the gallery of the cardinal's palace. The superior praises awarded to Agostino inflamed the jealousy of Annibale, already kindled by the brilliant reception given by the pupils of the Incamminati to Agostino's still highly celebrated picture of the "Communion of St Jerome," and the latter was dismissed to Parma to paint the great saloon of the Casino. Here he died in 1602, when on the eve of finishing his renowned painting of "Celestial, Terrestrial and Venal Love." Annibale continued to work alone at the Farnese gallery till the designs were completed; but, disappointed at the miserable remuneration offered by the cardinal, he retired to Naples, where an unsuccessful contest for a great work in the church of the Jesuits threw him into a fever, of which he died in 1609. Lodovico always remained at his academy in Bologna (excepting for a short visit to his cousin at Rome), though invited to execute paintings in all parts of the country. He died in 1619, and was interred in the church of Santa Maria Maddalena. The works of Lodovico are numerous in the chapels of Bologna. The most famous are--The "Madonna standing on the moon, with St Francis and St Jerome beside her, attended by a retinue of angels"; "John the Baptist," "St Jerome," "St Benedict" and "St Cecilia"; and the "Limbo of the Fathers." He was by far the most amiable of the three painters, rising superior to all feelings of jealousy towards his rivals, and though he received large sums for his productions, yet, from his almost unparalleled liberality to the students of the academy, he died poor. With skill in painting Agostino combined the greatest proficiency in engraving (which he had studied under Cornelius de Cort) and high accomplishments as a scholar. He died not untroubled by remorse for the indecencies which, in accordance with the corruption of the time, he had introduced into some of his engravings. The works of Annibale are more diversified in style than those of the others, and comprise specimens of painting after the manner of Correggio, Titian, Paolo Veronese, Raphael and Michelangelo. The most distinguished are the "Dead Christ in the lap of the Madonna"; the "Infant and St John"; "St Catherine"; "St Roch distributing alms" (now in the Dresden gallery); and the "Saviour wailed over by the Maries," at present in possession of the earl of Carlisle. He frequently gave great importance to the landscape in his compositions. The reputation of Annibale is tarnished by his jealousy and vindictiveness towards his brother, and the licentiousness of his disposition, which contributed to bring him to a comparatively early grave.

The three Caracci were the founders of the so-called Eclectic school of painting,--the principle of which was to study in the works of the great masters the several excellences for which they had been respectively pre-eminent, and to combine these in the productions of the school itself; for instance, there was to be the design of Raphael, the power of Michelangelo, the colour of Titian, and so on.

See A. Venturi, _I Caracci e la loro scuola_, 1895. (W. M. R.)

CARACCIOLO, FRANCESCO, PRINCE (1732-1799), Neapolitan admiral and revolutionist, was born on the 18th of January 1732, of a noble Neapolitan family. He entered the navy and learned his seamanship under Rodney. He fought with distinction in the British service in the American War of Independence, against the Barbary pirates, and against the French at Toulon under Lord Hotham. The Bourbons placed the greatest confidence in his skill. When on the approach of the French to Naples King Ferdinand IV. and Queen Mary Caroline fled to Sicily on board Nelson's ship the "Vanguard" (December 1798), Caracciolo escorted them on the frigate "Sannita." He was the only prominent Neapolitan trusted by the king, but even the admiral's loyalty was shaken by Ferdinand's cowardly flight. On reaching Palermo Caracciolo asked permission to return to Naples to look after his own private affairs (January 1799). This was granted, but when he arrived at Naples he found all the aristocracy and educated middle classes infatuated with the French revolutionary ideas, and he himself was received with great enthusiasm. He seems at first to have intended to live a retired life; but, finding that he must either join the Republican party or escape to Procida, then in the hands of the English, in which case even his intimates would regard him as a traitor and his property would have been confiscated, he was induced to adhere to the new order of things and took command of the republic's naval forces. Once at sea, he fought actively against the British and Neapolitan squadrons and prevented the landing of some Royalist bands. A few days later all the French troops in Naples, except 500 men, were recalled to the north of Italy.

Caracciolo then attacked Admiral Thurn, who from the "Minerva" commanded the Royalist fleet, and did some damage to that vessel. But the British fleet on the one hand and Cardinal Fabrizio Ruffo's army on the other made resistance impossible. The Republicans and the 500 French had retired to the castles, and Caracciolo landed and tried to escape in disguise. But he was betrayed and arrested by a Royalist officer, who on the 29th of June brought him in chains on board Nelson's flagship the "Foudroyant." It is doubtful whether Caracciolo should have been included in the capitulation concluded with the Republicans in the castles, as that document promised life and liberty to those who surrendered before the blockade of the forts, whereas he was arrested afterwards, but as the whole capitulation was violated the point is immaterial. Moreover, the admiral's fate was decided even before his capture, because on the 27th of June the British minister, Sir W. Hamilton, had communicated to Nelson Queen Mary Caroline's wish that Caracciolo should be hanged. As soon as he was brought on board, Nelson ordered Thurn to summon a court martial composed of Caracciolo's former officers, Thurn himself being a personal enemy of the accused. The court was held on board the "Foudroyant," which was British territory--a most indefensible proceeding. Caracciolo was charged with high treason; he had asked to be judged by British officers, which was refused, nor was he allowed to summon witnesses in his defence. He was condemned to death by three votes to two, and as soon as the sentence was communicated to Nelson the latter ordered that he should be hanged at the yard-arm of the "Minerva" the next morning, and his body thrown into the sea at sundown. Even the customary twenty-four hours' respite for confession was denied him, and his request to be shot instead of hanged refused. The sentence was duly carried out on the 30th of June 1799.

Caracciolo was technically a traitor to the king whose uniform he had worn, but apart from the wave of revolutionary enthusiasm which had spread all over the educated classes of Italy, and the fact that treason to a government like that of the Neapolitan Bourbons could hardly be regarded as a crime, there was no necessity for Nelson to make himself the executor of the revenge of Ferdinand and Mary Caroline. His greatest offence, as Captain Mahan remarks (_Life of Nelson_, i. 440), was committed against his own country by sacrificing his inalienable character as the representative of the king of Great Britain to his secondary and artificial character as delegate of the king of Naples. The only explanation of Nelson's conduct is to be found in his infatuation for Lady Hamilton, whose low ambition made her use her influence over him in the interest of Queen Mary Caroline's malignant spite.

AUTHORITIES.--Besides the general works on Nelson and Naples, such as
P. Colletta's _Storia del Reame di Napoli_ (Florence, 1848), there is
a large amount of special literature on the subject. _Nelson and the
Neapolitan Jacobins_ (Navy Records Society, 1903), contains all the
documents on the episode, including those incorrectly transcribed by
A. Dumas in his _Borboni di Napoli_ (Naples, 1862-1863), with an
introduction defending Nelson by H.C. Gutteridge; the work contains a
bibliography. The case against Nelson is set forth by Professor P.
Villari in his article "Nelson, Caracciolo, e la Repubblica
Napolitana" (_Nuova Antologia_, 16th February 1899); Captain A.T.
Mahan has replied in "The Neapolitan Republic and Nelson's Accusers"
(_English Historical Review_, July 1899), "Nelson at Naples" (_ibid._,
October 1900), and "Nelson at Naples" (_Athenaeum_, 8th July 1899);

Giglioli, _Naples in 1799_ (London, 1903); Freiherr von Helfert,

Republik des Jahres 1799_ (Leipzig, 1884). (L. V.*)

CARACOLE (a Fr. word, the origin of which is doubtful, meaning the wheeling about of a horse; in Spanish and Portuguese _caracol_ means a snail with a spiral shell), a turn or wheeling in horsemanship to the left or right, or to both alternately, so that the movements of the horse describe a zig-zag course. The term has been used loosely and erroneously to describe any display of fancy riding. It is also used for a spiral staircase in a tower.

CARACTACUS, strictly CARATACUS, the Latin form of a Celtic name, which survives in Caradoc and other proper names. The most famous bearer of the name was the British chieftain who led the native resistance to the Roman invaders in A.D. 48-51, and was finally captured and sent to Rome (Tac. _Ann._ xii. 33, Dio. lx.). Two old camps on the Welsh border are now called Caer Caradoc, but the names seem to be the invention of antiquaries and not genuinely ancient memorials of the Celtic hero.

CARADOC SERIES, in geology, the name introduced by R.I. Murchison in 1839 for the sandstone series of Caer Caradoc in Shropshire, England. The limits of Murchison's Caradoc series have since been somewhat modified, and through the labours of C. Lapworth the several members of the series have been precisely defined by means of graptolitic zones. These zones are identical with those found in the rocks of the same age in North Wales, the Bala series (q.v.), and the terms Bala or Caradoc series are used indifferently by geologists when referring to the uppermost substage of the Ordovician System. The Ordovician rocks of the Caradoc district have been subdivided into the following beds, in descending order: the _Trinucleus_ shales, Acton Scott beds, Longville flags, Chatwell and Soudley sandstones, Harnage shales and Hoar Edge grits and limestone. In the Corndon district in the same county the Caradoc series is represented by the Harrington group of ashes and shales and the Spy Wood group beneath them; these two groups of strata are sometimes spoken of as the Chirbury series. In the Breidden district are the barren Criggeon shales with ashes and flows of andesite.

In the Lake district the Coniston limestone series represents the
Upper Caradocian, the lower portion being taken up by part of the
great Borrowdale volcanic series of rocks. The Coniston limestone
series contains the following subdivisions:--

Ashgill group (Ashgill shales and _Staurocephalus_ limestone).

Kiesley limestone.

Sleddale group (Applethwaite beds = Upper Coniston limestone
conglomerate; Yarlside rhyolite; stye end beds = Lower Coniston
limestone).

Roman Fell group (Corona beds).

The Dufton shales and Drygill shales are equivalents of the Sleddale
group.

Rocks of Caradoc age are well developed in southern Scotland; in the
Girvan district they have been described as the Ardmillan series with
the Drummock group and Barren Flagstone group in the upper portion,
and the Whitehouse, Ardwell and Balclatchie groups in the lower part.
Similarly, two divisions, known as the Upper and Lower Hartfell
series, are recognized in the southern and central area, in
Peeblesshire, Ayrshire and Dumfriesshire.

In Ireland the Caradoc or Bala series is represented by the limestones
of Portraine near Dublin and of the Chair of Kildare; by the
Ballymoney series of Wexford and Carnalea shales of Co. Down. In the
Lough Mask district beds of this age are found, as in Wales,
interstratified with volcanic lavas and tuffs. Other localities are
known in counties Tyrone, Meath and Louth, also in Lambay Island.

CARALES (Gr. [Greek: K['a]ralis], mod. _Cagliari_, q.v.), the most important ancient city of Sardinia, situated on the south coast of the island. Its foundation is generally attributed to the Carthaginians, and Punic tombs exist in considerable numbers near the present cemetery on the east and still more on the rocky plateau to the north-west of the town. It first appears in Roman history in the Second Punic War, and probably obtained full Roman civic rights from Julius Caesar. In imperial times it was the most important town in the island, mainly owing to its fine sheltered harbour, where a detachment of the _classis Misenas_ was stationed. In the 4th and 5th centuries it was probably the seat of the _praeses Sardiniae_. It is mentioned as an important harbour in the Gothic and Gildonic wars. It was also the chief point of the road system of Sardinia. Roads ran hence to Olbia by the east coast, and through the centre of the island, to Othoca (Oristano) direct, and thence to Olbia (probably the most frequented route), through the mining district to Sulci and along the south and west coasts to Othoca. The hill occupied by the Pisan fortifications and the medieval town within them must have been the acropolis of the Carthaginian settlement; it is impossible to suppose that a citadel presenting such natural advantages was not occupied. The Romans, too, probably made use of it, though the lower quarters were mainly occupied in imperial times. A. Taramelli (_Notizie degli Scavi_, 1905, 41 seq.) rightly points out that the nucleus of the Roman _municipium_ is probably represented by the present quarter of the Marina, in which the streets intersect at right angles and Roman remains are frequently found in the subsoil. An inscription found some way to the north towards the amphitheatre speaks of paving in the squares and streets, and of drains constructed under Domitian in A.D. 83 (F. Vivanet in _Notizie degli Scavi_, 1897, 279). The amphitheatre occupies a natural depression in the rock just below the acropolis, and open towards the sea with a fine view. Its axes are 95-1/2 and 79 yds., and it is in the main cut in the rock, though some parts of it are built with concrete. Below it, to the south, are considerable remains of ancient reservoirs for rain-water, upon which the city entirely depended. This nucleus extended both to the east and to the west; in the former direction it ran some way inland, on the east of the castle hill. Here were the _ambulationes_ or public promenades constructed by the pro-consul Q. Caecilius Metellus before A.D. 6 (_Corp. Inscrip. Lat._ x., Berlin, 1883, No. 7581). Here also, not far from the shore, the remains of Roman baths, with a fine coloured mosaic pavement, representing deities riding on marine monsters, were found in 1907. To the east was the necropolis of Bonaria, where both Punic and Roman tombs exist, and where, on the site of the present cemetery, Christian catacombs have been discovered (F. Vivanet in _Notizie degli Scavi_, 1892, 183 seq.; G. Pinza in _Nuovo Bullettino di Archeologia Cristiana_, 1901, 61 seq.). But the western quarter seems to have been far more important; it extended along the lagoon of S. Gilla (which lies to the north-west of the town, and which until the middle ages was an open bay) and on the lower slopes of the hill which rises above it. The chief discoveries which have been made are noted by Taramelli (loc. cit.) and include some important buildings, of which a large Roman house (or group of houses) is the only one now visible (G. Spano in _Notizie degli Scavi_, 1876, 148, 173; 1877, 285; 1880, 105, 405). Beyond this quarter begins an extensive Roman necropolis extending along the edge of the hill north-east of the high road leading to the north-west; the most important tomb is the so-called Grotta delle Vipere, the rock-hewn tomb of Cassius Philippus and Atilia Pomptilla, the sides of which are covered with inscriptions (_Corpus Inscr. Lat._ x., Berlin, 1883, Nos. 7563-7578). Other tombs are also to be found on the high ground near the Punic tombs already mentioned. The latter are hewn perpendicularly in the rock, while the Roman tombs are chambers excavated horizontally. In the lagoon itself were found a large number of terra cottas, made of local clay, some being masks of both divinities and men (among them grotesques) others representing hands and feet, others various animals, and of _amphorae_ of various sizes and other vases. Some of the _amphorae_ contained animals' bones, possibly the remains of sacrifices. These objects are of the Punic period; they were all found in groups, and had apparently been arranged on a platform of piles in what was then a bay, in readiness for shipment (F. Vivanet in _Notizie degli Scavi_, 1893, 255). It is probable that the acropolis of Carales was occupied even in prehistoric times; but more abundant traces of prehistoric settlements (pottery and fragments of obsidian, also kitchen middens, containing bones of animals and shells of molluscs used for human food) have been found on the Capo S. Elia to the south-east of the modern town (see A. Taramelli in _Notizie degli Scavi_, 1904, 19 seq.). An inscription records the existence of a temple of Venus Erycina on this promontory in Roman times. The museum contains an interesting collection of objects from many of the sites mentioned, and also from other parts of the island; it is in fact the most important in Sardinia, and is especially strong in prehistoric bronzes (see SARDINIA).

For the Roman inscriptions see _C.I.L._ cit., Nos. 7552-7807.

CARAN D'ACHE, the pseudonym (meaning "lead-pencil") of Emmanuel Poire (1858-1909), French artist and illustrator, who was born and educated at Moscow, being the grandson of one of Napoleon's officers who had settled in Russia. He determined to be a military painter, and when he arrived in Paris from Russia he found an artistic adviser in Detaille. He served five years in the army, where the principal work allotted to him was the drawing of uniforms for the ministry of war. He embellished a short-lived journal, _La Vie militaire_, with a series of illustrations, among them being some good-tempered caricatures of the German army, which showed how accurately he was acquainted with military detail. His special gift lay in pictorial anecdote, the story being represented at its different stages with irresistible effect, in the artist's own mannered simplicity. Much of his work was contributed to _La Vie parisienne_, _Le Figaro illustre_, _La Caricature_, _Le Chat noir_, and he also issued various albums of sketches, the _Carnet de cheques_, illustrating the Panama scandals, _Album de croquis militaires et d'histoire sans legendes_, _Histoire de Marlborough_, &c., besides illustrating a good many books, notably the _Prince Kozakokoff_ of Bemadaky. He died on the 26th of February 1909.

A collection of his work was exhibited at the Fine Art Society's rooms
in London in 1898. The catalogue contained a prefatory note by M.H.
Spielmann.

CARAPACE (a Fr. word, from the Span, _carapacho_, a shield or armour), the upper shell of a crustacean, tortoise or turtle. The covering of the armadillo is called a carapace, as is also the hard case in which certain of the Infusoria are enclosed.

CARAPEGUA, an interior town of Paraguay, 37 m. S.E. of Asuncion on the old route between that city and the missions. Pop. (est.) 13,000 (probably the population of the large rural district about the town is included in this estimate). The town (founded in 1725) is situated in a fertile country producing cotton, tobacco, Indian corn, sugar-cane and mandioca. It has two schools, a church and modern public buildings.

CARAT (Arab. _Q[-i]r[-a]t_, weight of four grains; Gr. _[Greek: ker['a]tion]_, little horn, the fruit of the carob or locust tree), a small weight (originally in the form of a seed) used for diamonds and precious stones, and a measure for determining the fineness of gold. The exact weight of the carat, in practice, now varies slightly in different places. In 1877 a syndicate of London, Paris and Amsterdam jewellers fixed the weight at 205 milligrammes (3.163 troy grains). The South African carat, according to Gardner Williams (general manager of the De Beers mines), is equal to 3.174 grains (_The Diamond Mines of South Africa_, 1902). The fineness of gold is measured by a ratio with 24 carats as a standard; thus 2 parts of alloy make it 22-carat gold, and so on.

CARAUSIUS, MARCUS AURELIUS, tyrant or usurper in Britain, A.D. 286-293, was a Menapian from Belgic Gaul, a man of humble origin, who in his early days had been a pilot. Having entered the Roman army, he rapidly obtained promotion, and was stationed by the emperor Maximian at Gessoriacum (Bononia, _Boulogne_) to protect the coasts and channel from Frankish and Saxon pirates. He at first acted energetically, but was subsequently accused of having entered into partnership with the barbarians and was sentenced to death by the emperor. Carausius thereupon crossed over to Britain and proclaimed himself an independent ruler. The legions at once joined him; numbers of Franks enlisted in his service; an increased and well-equipped fleet secured him the command of the neighbouring seas. In 289 Maximian attempted to recover the island, but his fleet was damaged by a storm and he was defeated. Maximian and Diocletian were compelled to acknowledge the rule of Carausius in Britain; numerous coins are extant with the heads of Carausius, Diocletian and Maximian, bearing the legend "Carausius et fratres sui." In 292 Constantius Chlorus besieged and captured Gessoriacum (hitherto in possession of Carausius), together with part of his fleet and naval stores. Constantius then made extensive preparations to ensure the reconquest of Britain, but before they were completed Carausius was murdered by Allectus, his praefect of the guards (Aurelius Victor, _Caesares_, 39; Eutropius ix. 21, 22; Eumenius, _Panegyrici_ ii. 12, v. 12). A Roman mile-stone found near Carlisle (1895) bears the inscription IMP. C[aes] M. AUR[elius] MAUS. The meaning of MAUS is doubtful, but it may be an anticipation of ARAUS (see F.J. Haverfield in _Cumberland and Westmoreland Antiquarian Soc. Transactions_, 1895, p. 437).

A copper coin found at Richborough, inscribed _Domino Carausio Ces._, must be ascribed to a Carausius of later date, since the type of the reverse is not found until the middle of the 4th century at the earliest. Nothing is known of this Carausius (A.J. Evans in _Numismatic Chronicle_, 1887, "On a coin of a second Carausius Caesar in Britain in the Fifth Century").

See J. Watts de Peyster, _The History of Carausius, the Dutch
Augustus_ (1858); P.H. Webb, _The Reign and Coinage of Carausius_
(1908).

CARAVACA, a town of south-eastern Spain, in the province of Murcia; near the left bank of the river Caravaca, a tributary of the Segura. Pop. (1900) 15,846. Caravaca is dominated by the medieval castle of Santa Cruz, and contains several convents and a fine parish church, with a miraculous cross celebrated for its healing power, in honour of which a yearly festival is held on the 3rd of May. The hills which extend to the north are rich in marble and iron. Despite the lack of railway communication, the town is a considerable industrial centre, with large iron-works, tanneries and manufactories of paper, chocolate and oil.

CARAVAGGIO, MICHELANGELO AMERIGHI (or MERIGI) DA (1569-1609), Italian painter, was born in the village of Caravaggio, in Lombardy, from which he received his name. He was originally a mason's labourer, but his powerful genius directed him to painting, at which he worked with immitigable energy and amazing force. He despised every sort of idealism whether noble or emasculate, became the head of the Naturalisti (unmodified imitators of ordinary nature) in painting, and adopted a style of potent contrasts of light and shadow, laid on with a sort of fury, indicative of that fierce temper which led the artist to commit a homicide in a gambling quarrel at Rome. To avoid the consequences of his crime he fled to Naples and to Malta, where he was imprisoned for another attempt to avenge a quarrel. Escaping to Sicily, he was attacked by a party sent in pursuit of him, and severely wounded. Being pardoned, he set out for Rome; but having been arrested by mistake before his arrival, and afterwards released, and left to shift for himself in excessive heat, and still suffering from wounds and hardships, he died of fever on the beach at Pontercole in 1609. His best pictures are the "Entombment of Christ," now in the Vatican; "St Sebastian," in the Roman Capitol; a magnificent whole-length portrait of a grand-master of the Knights of Malta, Alof de Vignacourt, and his page, in the Louvre; and the Borghese "Supper at Emmaus."

CARAVAGGIO, POLIDORO CALDARA DA (1495 or 1492-1543), a celebrated painter of frieze and other decorations in the Vatican. His merits were such that, while a mere mortar-carrier to the artists engaged in that work, he attracted the admiration of Raphael, then employed on his great pictures in the Loggie of the palace. Polidoro's works, as well as those of his master, Maturino of Florence, have mostly perished, but are well known by the fine etchings of P.S. Bartoli, C. Alberti, &c. On the sack of Rome by the army of the Constable de Bourbon in 1527, Polidoro fled to Naples. Thence he went to Messina, where he was much employed, and gained a considerable fortune, with which he was about to return to the mainland of Italy when he was robbed and murdered by an assistant, Tonno Calabrese, in 1543. Two of his principal paintings are a Crucifixion, painted in Messina, and "Christ bearing the Cross" in the Naples gallery.

CARAVAN (more correctly _Karwan_), a Persian word, adopted into the later Arabic vocabulary, and denoting, throughout Asiatic Turkey and Persia,[1] a body of traders travelling together for greater security against robbers (and in particular against Bedouins, Kurds, Tatars and the like, whose grazing-grounds the proposed route may traverse) and for mutual assistance in the matter of provisions, water and so forth. These precautions are due to the absence of settled government, inns and roads. These conditions having existed from time immemorial in the major part of western Asia, and still existing, caravans always have been the principal means for the transfer of merchandise. In these companies camels are generally employed for the transport of heavy goods, especially where the track, like that between Damascus and Bagdad, for example, lies across level, sandy and arid districts. The camels are harnessed in strings of fifty or more at a time, a hair-rope connecting the rear of one beast with the head of another; the leader is gaily decorated with parti-coloured trappings, tassels and bells; an unladen ass precedes the file, for luck, say some, for guidance, say others. Where the route is rocky and steep, as that between Damascus and Aleppo, mules, or even asses, are used for burdens. The wealthier members ride, where possible, on horseback. Every man carries arms; but these are in truth more for show than for use, and are commonly flung away in the presence of any serious robber attack. Should greater peril than ordinary be anticipated, the protection of a company of soldiers is habitually pre-engaged,--an expensive, and ordinarily a useless adjunct. A leader or director, called _Karawan-Bashi_ (headman), or, out of compliment, _Karawan-Seraskier_ (general), but most often simply designated _Rais_ (chief), is before starting appointed by common consent. His duties are those of general manager, spokesman, arbitrator and so forth; his remuneration is indefinite. But in the matter of sales or purchases, either on the way or at the destination, each member of the caravan acts for himself.

The number of camels or mules in a single caravan varies from forty or so up to six hundred and more; sometimes, as on the reopening of a long-closed route, it reaches a thousand. The ordinary caravan seasons are the months of spring, early summer and later autumn. Friday, in accordance with a recommendation made in the Koran itself, is the favourite day for setting out, the most auspicious hour being that immediately following noonday prayer. The first day's march never does more than just clear the starting-point. Subsequently each day's route is divided into two stages,--from 3 or 4 A.M. to about 10 in the forenoon, and from between 2 and 3 P.M. till 6 or even 8 in the evening. Thus the time passed daily on the road averages from ten to twelve hours, and, as the ordinary pace of a laden camel does not exceed 2 m. an hour, that of a mule being 2-3/4, a distance varying from 23 to 28 m. is gone over every marching day. But prolonged halts of two, three, four and even more days often occur. The hours of halt, start and movement, the precise lines of route, and the selection or avoidance of particular localities are determined by common consent. But if, as sometimes happens, the services of a professional guide, or those of a military officer have been engaged, his decisions are final. While the caravan is on its way, the five stated daily prayers are, within certain limits, anticipated, deferred or curtailed, so as the better to coincide with the regular and necessary halts,--a practice authorized by orthodox Mahommedan custom and tradition.

Two caravans are mentioned in Genesis xxxvii.; the route on which they were passing seems to have coincided with that nowadays travelled by Syrian caravans on their way to Egypt. Other allusions to caravans may be found in Job, in Isaiah and in the Psalms. Eastern literature is full of such references.

The yearly pilgrim-bands, bound from various quarters of the Mahommedan world to their common destination, Mecca, are sometimes, but inaccurately, styled by European writers caravans; their proper designation is _Hajj_, a collective word for pilgrimages and pilgrims. The two principal pilgrim-caravans start yearly, the one from Damascus, or, to speak more exactly, from Mozarib, a village station three days' journey to the south of the Syrian capital, the other from Cairo in Egypt.[2] This latter was formerly joined on its route, near Akaba of the Red Sea, by the North African Hajj, which, however, now goes from Egypt by sea from Suez; the former gathers up bands from Anatolia, Kurdistan, Mesopotamia and Syria. Besides these a third, but smaller Hajj of Persians, chiefly sets out from Suk-esh-Sheiukh, in the neighbourhood of Meshed Ali, on the lower Euphrates; a fourth of negroes, Nubians, etc., unites at Yambu on the Hejaz coast, whither they have crossed from Kosseir in Upper Egypt; a fifth of Indians and Malays, centres at Jidda; a sixth and seventh, of southern or eastern Arabs arrive, the former from Yemen, the latter from Nejd.

The Syrian Hajj is headed by the pasha of Damascus, either in person or by a vicarious official of high rank, and is further accompanied by the _Sorrah Amir_ or "Guardian of the Purse," a Turkish officer from Constantinople. The Egyptian company is commanded by an amir or ruler, appointed by the Cairene government, and is accompanied by the famous "Mahmal," or sacred pavilion. The other bands above mentioned have each their own amir, besides their _mekowwams_ or agents, whose business it is to see after provisions, water and the like, and are not seldom encumbered with a numerous retinue of servants and other attendants. Lastly, a considerable force of soldiery accompanies both the Syrian and the Egyptian Hajj.

No guides properly so-called attend these pilgrim-caravans, the routes followed being invariably the same, and well known. But Bedouin bands generally offer themselves by way of escort, and not seldom designedly lead their clients into the dangers from which they bargain to keep them safe. This they are the readier to do because, in addition to the personal luxuries with which many of the pilgrims provide themselves for the journey, a large amount of wealth, both in merchandise and coins, is habitually to be found among the travellers, who, in accordance with Mahommedan tradition, consider it not merely lawful but praiseworthy to unite mercantile speculation with religious duty. Nor has any one, the pasha himself or the amir and the military, when present, excepted, any acknowledged authority or general control in the pilgrim-caravans; nor is there any orderly subdivision of management or service. The pilgrims do, indeed, often coalesce in companies among themselves for mutual help, but necessity, circumstance or caprice governs all details, and thus it happens that numbers, sometimes as many as a third of the entire Hajj, yearly perish by their own negligence or by misfortune,--dying, some of thirst, others of fatigue and sickness, others at the hand of robbers on the way. In fact the principal routes are in many places lined for miles together with the bones of camels and men.

The numbers which compose these pilgrim caravans are much exaggerated by popular rumour; yet it is certain that the Syrian and Egyptian sometimes amount to 5000 each, with 25,000 or 30,000 camels in train. Large supplies of food and water have to be carried, the more so at times that the pilgrim season, following as it does the Mahommedan calendar, which is lunar, falls for years together in the very hottest season. Hence, too, the journey is usually accomplished by night marches, the hours being from 3 to 4 P.M. to 6 or 7 A.M. of the following day. Torches are lighted on the road, the pace is slower than that of an ordinary caravan, and does not exceed 2 m. an hour.

CARAVANSERAI, a public building, for the shelter of a caravan (q.v.) and of wayfarers generally in Asiatic Turkey. It is commonly constructed in the neighbourhood, but not within the walls, of a town or village. It is quadrangular in form, with a dead wall outside; this wall has small windows high up, but in the lower parts merely a few narrow air-holes. Inside a cloister-like arcade, surrounded by cellular store-rooms, forms the ground floor, and a somewhat lighter arcade, giving access to little dwelling-rooms, runs round it above. Broad open flights of stone steps connect the storeys. The central court is open to the sky, and generally has in its centre a well with a fountain-basin beside it. A spacious gateway, high and wide enough to admit the passage of a loaded camel, forms the sole entrance, which is furnished with heavy doors, and is further guarded within by massive iron chains, drawn across at night. The entry is paved with flagstones, and there are stone seats on each side. The court itself is generally paved, and large enough to admit of three or four hundred crouching camels or tethered mules; the bales of merchandise are piled away under the lower arcade, or stored up in the cellars behind it. The upstairs apartments are for human lodging; cooking is usually carried on in one or more corners of the quadrangle below. Should the caravanserai be a small one, the merchants and their goods alone find place within, the beasts of burden being left outside. A porter, appointed by the municipal authority of the place, is always present, lodged just within the gate, and sometimes one or more assistants. These form a guard of the building and of the goods and persons in it, and have the right to maintain order and, within certain limits, decorum; but they have no further control over the temporary occupants of the place, which is always kept open for all arrivals from prayer-time at early dawn till late in the evening. A small gratuity is expected by the porter, but he has no legal claim for payment, his maintenance being provided for out of the funds of the institution. Neither food nor provender is supplied.

Many caravanserais in Syria, Mesopotamia and Anatolia have considerable architectural merit; their style of construction is in general that known as Saracenic; their massive walls are of hewn stone; their proportions apt and grand. The portals especially are often decorated with intricate carving; so also is the prayer-niche within. These buildings, with their belongings, are works of charity, and are supported, repaired and so forth out of funds derived from pious legacies, most often of land or rentals. Sometimes a municipality takes on itself to construct and maintain a caravanserai; but in any case the institution is tax-free, and its revenues are inalienable. When, as sometimes happens, those revenues have been dissipated by peculation, neglect or change of times, the caravanserai passes through downward stages of dilapidation to total ruin (of which only too many examples may be seen) unless some new charity intervene to repair and renew it.

_Khans, i.e._ places analogous to inns and hotels, where not lodging only, but often food and other necessaries or comforts may be had for payment, are sometimes by inaccurate writers confounded with caravanserais. They are generally to be found within the town or village precincts, and are of much smaller dimensions than caravanserais. The khan of Asad Pasha at Damascus is a model of constructive skill and architectural beauty.

CARAVEL, or CARVEL (from the Gr. [Greek: k['a]rabos], a light ship, through the Ital. _carabella_ and the Span. _carabas_), a name applied at different times and in different countries to ships of very varying appearance and build, as in Turkey to a ship of war, and in France to a small boat used in the herring fishery. In the 15th and 16th centuries, caravels were much used by the Portuguese and Spanish for long voyages. They were roundish ships, with a double tower at the stern, and a single one in the bows, and were galley rigged. Two out of the three vessels in which Columbus sailed on his voyage of discovery to America were "caravels." Carvel, the older English form, is now used only in the term "carvel-built," for a boat in which the planking is flush with the edges laid side to side, in distinction from "clinker-built," where the edges overlap.

CARAVELLAS, a small seaport of southern Bahia, Brazil, on the Caravellas river a few miles above its mouth, which is dangerously obstructed by sandbars. Pop. (1890) of the municipality 5482, about one-half of whom lived in the town. Caravellas was once the centre of a flourishing whale fishery, but has since fallen into decay. It is the port of the Bahia & Minas railway, whose traffic is comparatively unimportant.

CARAWAY, the fruit, or so-called seed, of _Carum Carui_, an umbelliferous plant growing throughout the northern and central parts of Europe and Asia, and naturalized in waste places in England. The plant has finely-cut leaves and compound umbels of small white flowers. The fruits are laterally compressed and ovate, the mericarps (the two portions into which the ripe fruit splits) being subcylindrical, slightly arched, and marked with five distinct pale ridges. Caraways evolve a pleasant aromatic odour when bruised, and they have an agreeable spicy taste. They yield from 3 to 6% of a volatile oil, the chief constituent of which is cymene aldehyde. Cymene itself is present, having the formula CH3C6H4CH(CH3)2; also carvone C10H14O, and limonene, a terpene. The dose of the oil is 1/2-3 minims. The plant is cultivated in north and central Europe, and Morocco, as well as in the south of England, the produce of more northerly latitudes being richer in essential oil than that grown in southern regions. The essential oil is largely obtained by distillation for use in medicine as an aromatic stimulant and carminative, and as a flavouring material in cookery and in liqueurs for drinking. Caraways are, however, more extensively consumed entire in certain kinds of cheese, cakes and bread, and they form the basis of a popular article of confectionery known as caraway comfits.

CARBALLO, a town of north-western Spain, in the province of Corunna; on the right bank of the river Allones, 20 m. S.W. of the city of Corunna. Pop. (1900) 13,032. Carballo is the central market of a thriving agricultural district. At San Juan de Carballo, on the opposite bank of the Allones, there are hot sulphurous springs.

CARBAZOL, C12H9N, a chemical constituent of coal-tar and crude anthracene. From the latter it may be obtained by fusion with caustic potash when it is converted into carbazol-potassium, which can be easily separated by distilling off the anthracene. It may be prepared synthetically by passing the vapours of diphenylamine or aniline through a red-hot tube; by heating diorthodiaminodiphenyl with 25% sulphuric acid to 200 deg. C. for 15 hours; by heating orthoaminodiphenyl with lime; or by heating thiodiphenylamine with copper powder. It is also obtained as a decomposition product of brucine or strychnine, when these alkaloids are distilled with zinc dust. It is easily soluble in the common organic solvents, and crystallizes in plates or tables melting at 238 deg. C. It is a very stable compound, possessing feebly basic properties and characterized by its ready sublimation. It distils unchanged, even when the operation is carried out in the presence of zinc dust. On being heated with caustic potash in a current of carbonic acid, it gives carbazol carbonic acid C12H8N.COOH; melted with oxalic acid it gives carbazol blue. It dissolves in concentrated sulphuric acid to a clear yellow solution. The potassium salt reacts with the alkyl iodides to give N-substituted alkyl derivatives. It gives the pine-shaving reaction, in this respect resembling pyrrol (q.v.).

CARBIDE, in chemistry, a compound of carbon with another element. The introduction of the electric furnace into practical chemistry was followed by the preparation of many metallic carbides previously unknown, some of which, especially calcium carbide, are now of great commercial importance. Carbides of the following general formulae have been obtained by H. Moissan (M denotes an atom of metal and C of carbon):--

M3C = manganese, iron; M2C = molybdenum; M3C2 = chromium; MC = zirconium; M4C3 = beryllium, aluminium; M2C3 = uranium; MC2 = barium, calcium, strontium, lithium, thorium, &c.; MC4 = chromium.

The principal methods for the preparation of carbides may be classified as follows:--(1) direct union at a high temperature, e.g. lithium, iron, chromium, tungsten, &c.; (2) by the reduction of oxides with carbon at high temperatures, e.g. calcium, barium, strontium, manganese, chromium, &c.; (3) by the reduction of carbonates with magnesium in the presence of carbon, e.g. calcium, lithium; (4) by the action of metals on acetylene or metallic derivatives of acetylene, e.g., sodium, potassium. The metallic carbides are crystalline solids, the greater number being decomposed by water into a metallic hydrate and a hydrocarbon; sometimes hydrogen is also evolved. Calcium carbide owes its industrial importance to its decomposition into acetylene; lithium carbide behaves similarly. Methane is yielded by aluminium and beryllium carbides, and, mixed with hydrogen, by manganese carbide. The important carbides are mentioned in the separate articles on the various metals. The commercial aspect of calcium carbide is treated in the article ACETYLENE.

CARBINE (Fr. _carabine_, Ger. _Karabiner_), a word which came into use towards the end of the 16th century to denote a form of small fire-arm, shorter than the musket and chiefly used by mounted men. It has retained this significance, through all subsequent modifications of small-arm design, to the present day, and is now as a rule a shortened and otherwise slightly modified form of the ordinary rifle (q.v.).

CARBO, the name of a Roman plebeian family of the gens Papiria. The following are the most important members in Roman history:--

1. GAIUS PAPIRIUS CARBO, statesman and orator. He was associated with C. Gracchus in carrying out the provisions of the agrarian law of Tiberius Gracchus (see GRACCHUS). When tribune of the people (131 B.C.) he carried a law extending voting by ballot to the enactment and repeal of laws; another proposal, that the tribunes should be allowed to become candidates for the same office in the year immediately following, was defeated by the younger Scipio Africanus. Carbo was suspected of having been concerned in the sudden death of Scipio (129), if not his actual murderer. He subsequently went over to the optimates, and (when consul in 120) successfully defended Lucius Opimius, the murderer of Gaius Gracchus, when he was impeached for the murder of citizens without a trial, and even went so far as to say that Gracchus had been justly slain. But the optimates did not trust Carbo. He was impeached by Licinius Crassus on a similar charge, and, feeling that he had nothing to hope for from the optimates and that his condemnation was certain, he committed suicide.

See Livy, _Epit._ 59; Appian, _Bell. Civ._ i. 18: Vell. Pat. ii. 4;
Val. Max. iii. 7. 6; A.H.J. Greenidge, _History of Rome_ (1904).

2. His son, GAIUS PAPIRIUS CARBO, surnamed Arvina, was a staunch supporter of the aristocracy, and was put to death by the Marian party in 82. He is known chiefly for the law (Plautia Papiria) carried by him and M. Plautius Silvanus when tribunes of the people in 90 (or 89), whereby the Roman franchise was offered to every Italian ally domiciled in Italy at the time when the law was enacted, provided he made application personally within sixty days to the praetor at Rome (see ROME: _History_, II. "The Republic," Period C.). The object of the law was to conciliate the states at war with Rome and to secure the loyalty of the federate states. Like his father, Carbo was an orator of distinction.
