Chapter XXX: Part 30

This operation is now advised for (1) extreme degrees of pelvic contraction, (2) any malformation or tumour of the uterus, cervix or vagina, which would render the birth of the child through the natural passages impossible, (3) maternal complications, as eclampsia and concealed accidental haemorrhage, and (4) at the death of the mother for the purpose of saving the child.

CAESAREA PALAESTINA, a town built by Herod about 25-13 B.C., on the sea-coast of Palestine, 30 miles N. of Joppa, on the site of a place previously called _Tunis Stratonis_. Remains of all the principal buildings erected by Herod existed down to the end of the 19th century; the ruins were much injured by a colony of Bosnians established here in 1884. These buildings are a temple, dedicated to Caesar; a theatre; a hippodrome; two aqueducts; a boundary wall; and, chief of all, a gigantic mole, 200 ft. wide, built of stones 50 ft. long, in 20 fathoms of water, protecting the harbour on the south and west. The harbour measures 180 yds. across. The massacre of Jews at this place led to the Jewish rebellion and to the Roman war. Vespasian made it a colony and called it Flavia: the old name, however, persisted, and still survives as _Kaisarieh_. Eusebius was archbishop here (A.D. 315-318). It was captured by the Moslems in 638 and by the Crusaders in 1102, by Saladin in 1187, recaptured by the Crusaders in 1191, and finally lost by them in 1265, since when till its recent settlement it has lain in ruins. Remains of the medieval town are also visible, consisting of the walls (one-tenth the area of the Roman city), the castle, the cathedral (now covered by modern houses), and a church.

(R. A. S. M.)

CAESAREA PHILIPPI, the name of a town 95 miles N. of Jerusalem, 35 miles S.W. from Damascus, 1150 ft. above the sea, on the south base of Hermon, and at an important source of the Jordan. It does not certainly appear in the Old Testament history, though identifications with Baal-Gad and (less certainly) with Laish (Dan) have been proposed. It was certainly a place of great sanctity from very early times, and when foreign [v.04 p.0944] religious influences intruded upon Palestine, the cult of its local _numen_ gave place to the worship of Pan, to whom was dedicated the cave in which the copious spring feeding the Jordan arises. It was long known as _Panium_ or _Panias_, a name that has survived in the modern _Banias_. When Herod the Great received the territory from Augustus, 20 B.C., he erected here a temple in honour of his patron; but the re-foundation of the town is due to his son, Philip the Tetrarch, who here erected a city which he named _Caesarea_ in honour of Tiberius, adding _Philippi_ to immortalize his own name and to distinguish his city from the similarly-named city founded by his father on the sea-coast. Here Christ gave His charge to Peter (Matt. xvi. 13). Many Greek inscriptions have been found here, some referring to the shrine. Agrippa II. changed the name to _Neronias_, but this name endured but a short while. Titus here exhibited gladiatorial shows to celebrate the capture of Jerusalem. The Crusaders took the city in 1130, and lost it to the Moslems in 1165. Banias is a poor village inhabited by about 350 Moslems; all round it are gardens of fruit-trees. It is well watered and fertile. There are not many remains of the Roman city above ground. The Crusaders' castle of Subeibeh, one of the finest in Palestine, occupies the summit of a conical hill above the village.

(R. A. S. M.)

CAESIUM (symbol Cs, atomic weight 132.9), one of the alkali metals. Its name is derived from the Lat. _caesius_, sky-blue, from two bright blue lines of its spectrum. It is of historical importance, since it was the first metal to be discovered by the aid of the spectroscope (R. Bunsen, _Berlin Acad. Ber._, 1860), although caesium salts had undoubtedly been examined before, but had been mistaken for potassium salts (see C.F. Plattner, _Pog. Ann._, 1846, p. 443, on the analysis of pollux and the subsequent work of F. Pisani, _Comptes Rendus_, 1864, 58, p. 714). Caesium is found in the mineral springs of Frankenhausen, Montecatini, di Val di Nievole, Tuscany, and Wheal Clifford near Redruth, Cornwall (W.A. Miller, _Chem. News_, 1864, 10, p. 181), and, associated with rubidium, at Dürkheim; it is also found in lepidolite, leucite, petalite, triphylline and in the carnallite from Stassfurt. The separation of caesium from the minerals which contain it is an exceedingly difficult and laborious process. According to R. Bunsen, the best source of rubidium and caesium salts is the residue left after extraction of lithium salts from lepidolite. This residue consists of sodium, potassium and lithium chlorides, with small quantities of caesium and rubidium chlorides. The caesium and rubidium are separated from this by repeated fractional crystallization of their double platinum chlorides, which are much less soluble in water than those of the other alkali metals (R. Bunsen, _Ann._, 1862, 122, p. 347; 1863, 125, p. 367). The platino-chlorides are reduced by hydrogen, and the caesium and rubidium chlorides extracted by water. See also A. Schrötter (_Jour. prak. Chem._, 1864, 93, p. 2075) and W. Heintz (_Journ. prak. Chem._, 1862, 87, p. 310). W. Feit and K. Kubierschky (_Chem. Zeit._, 1892, 16, p. 335) separate rubidium and caesium from the other alkali metals by converting them into double chlorides with stannic chloride; whilst J. Redtenbacher (_Jour. prak. Chem._, 1865, 94, p. 442) separates them from potassium by conversion into alums, which C. Setterberg (_Ann._, 1882, 211, p. 100) has shown are very slightly soluble in a solution of potash alum. In order to separate caesium from rubidium, use is made of the different solubilities of their various salts. The bitartrates RbHC_4H_40_6 and CsHC_4H_40_6 have been employed, as have also the alums (see above). The double chloride of caesium and antimony 3CsCl·2SbCl_3 (R. Godeffroy, _Ber._, 1874, 7, p. 375; _Ann._, 1876, 181, p. 176) has been used, the corresponding compound not being formed by rubidium. The metal has been obtained by electrolysis of a mixture of caesium and barium cyanides (C. Setterberg, _Ann._, 1882, 211, p. 100) and by heating the hydroxide with magnesium or aluminium (N. Beketoff, _Chem. Centralblatt_, 1889, 2, p. 245). L. Hackspill (_Comptes Rendus_, 1905, 141, p. 101) finds that metallic caesium can be obtained more readily by heating the chloride with metallic calcium. A special V-shaped tube is used in the operation, and the reaction commences between 400°C. and 500°C. It is a silvery white metal which burns on heating in air. It melts at 26° to 27°C. and has a specific gravity of 1.88 (15°C.).

The atomic weight of caesium has been determined by the analysis of its chloride and bromide. Richards and Archibald (_Zeit. anorg. Chem._, 1903, 34, p. 353) obtained 132.879 (O=16).

_Caesium hydroxide_, Cs(OH)_2, obtained by the decomposition of the sulphate with baryta water, is a greyish-white deliquescent solid, which melts at a red heat and absorbs carbon dioxide rapidly. It readily dissolves in water, with evolution of much heat. _Caesium chloride_, CsCl, is obtained by the direct action of chlorine on caesium, or by solution of the hydroxide in hydrochloric acid. It forms small cubes which melt at a red heat and volatilize readily. It deliquesces in moist air. Many double chlorides are known, and may be prepared by mixing solutions of the two components in the requisite proportions. The _bromide_, CsBr, and _iodide_, CsI, resemble the corresponding potassium salts. Many trihaloid salts of caesium are also known, such as CsBr_3, CsClBr_2, CsI_3, CsBrI_2, CsBr_2I, &c. (H.L. Wells and S.L. Penfield, _Zeit. fur anorg. Chem._, 1892, i, p. 85). _Caesium sulphate_, Cs_2SO_4, may be prepared by dissolving the hydroxide or carbonate in sulphuric acid. It crystallizes in short hard prisms, which are readily soluble in water but insoluble in alcohol. It combines with many metallic sulphates (silver, zinc, cobalt, nickel, &c.) to form double sulphates of the type Cs_2SO_4·RSO_4·6H_2O. It also forms a caesium-alum Cs_2SO_4·Al_2(SO_4)_3·24H_2O. _Caesium nitrate_, CsNO_3, is obtained by dissolving the carbonate in nitric acid, and crystallizes in glittering prisms, which melt readily, and on heating evolve oxygen and leave a residue of caesium nitrite. The carbonate, Cs_2CO_3, silicofluoride, Cs_2SiF_6, borate, Cs_2O·3B_2O_3, and the sulphides Cs_2S·4H_2O, Cs_2S_2·H_2O, Cs_2S_3·H_2O, Cs_2S_4 and Cs_2S_6·H_2O, are also known.

Caesium compounds can be readily recognized by the two bright blue lines (of wave length 4555 and 4593) in their flame spectrum, but these are not present in the spark spectrum. The other lines include three in the green, two in the yellow, and two in the orange.

CAESPITOSE (Lat. _caespes_, a sod), a botanical term for "growing in tufts," like many grasses.

CAESTUS, or CESTUS (from Lat. _caedo_, strike), a gauntlet or boxing-glove used by the ancient pugilists. Of this there were several varieties, the simplest and least dangerous being the _meilichae_ ([Greek: meilichai]), which consisted of strips of raw hide tied under the palm, leaving the fingers bare. With these the athletes in the _palaestrae_ were wont to practise, reserving for serious contests the more formidable kinds, such as the _sphaerae_ ([Greek: sphairai]), which were sewn with small metal balls covered with leather, and the terrible _murmekes_ ([Greek: murmêkes]), sometimes called "limb-breakers" ([Greek: guiotoroi]), which were studded with heavy nails. The straps ([Greek: himantes]) were of different lengths, many reaching to the elbow, in order to protect the forearm when guarding heavy blows (see J.H. Krause, _Gymnastik und Agonistik der Hellenen_, 1841). The _caestus_ is to be distinguished from _cestus_ (=embroidered, from [Greek: kentein]), an adjective used as a noun in the sense of "girdle," especially the girdle of Aphrodite, which was supposed to have the power of exciting love.

CAESURA (Lat. for "cutting," Gr. [Greek: tomê]), in prosody, a rest or pause, usually occurring about the middle of a verse, which is thereby separated into two parts ([Greek: kôla], members). In Greek and Latin hexameters the best and most common caesura is the penthemimeral (_i.e._ after the 5th half-foot):

[Greek: Mênin a | eide, the | a, | Pê | lêïa | deô Achi | lêos] Arma vi | rumque ca | no, Tro | jae qui | primus ab | oris.

Another caesura very common in Homer, but rare in Latin verse, is after the 2nd syllable of the 3rd dactyl:

[Greek: Oiô | noisi te | pasi Di | os d' ete | leieto | boulê.]

On the other hand, the hephthemimeral caesura (_i.e._ after the 7th half-foot) is common in Latin, but rare in Greek:

Formo | sam reso | nare do | ces Ama | ryllida | silvas.

The "bucolic" caesura, peculiar to Greek (so called because it is chiefly found in writers like Theocritus) occurs after the 4th dactyl:

[Greek: Ándra moi | ennepe, | Mousa, po | lutropon, | hos mala | polla]

In the pentameter verse of the elegiac distich the caesura is always penthemimeral. In the iambic trimeter (consisting of three dipodia or pairs of feet), both in Greek and Latin, the most usual caesura is the penthemimeral; next, the hephthemimeral:

[Greek: Ô tek | na Kad | mou tou | palai | nea | trophê] Supplex | et o | ro reg | na per | Proser | pinae.

[v.04 p.0945] Verses in which neither of these caesuras occurs are considered faulty. On the other hand, secondary or subsidiary caesuras are found in both Greek and Latin; thus, a trithemimeral (after the 3rd half-foot) is combined with the hephthemimeral, which divides the verse into two unequal parts. A caesura is often called masculine when it falls after a long, feminine when it falls after a short syllable.

The best treatise on Greek and Latin metre for general use is L. Müller, _Die Metrik der Griechen und Romer_ (1885); see also the article VERSE.

CAFFEINE, or THEINE (1.3.7 trimethyl 2.6 dioxypurin), C_8H_{10}N_4O_2·H_2O, a substance found in the leaves and beans of the coffee tree, in tea, in Paraguay tea, and in small quantities in cocoa and in the kola nut. It may be extracted from tea or coffee by boiling with water, the dissolved tannin precipitated by basic lead acetate, the solution filtered, excess of lead precipitated by sulphuretted hydrogen and the filtered liquid then evaporated to crystallization; or, tea is boiled with water, and the whole then evaporated to a syrup, which is mixed with slaked lime, evaporated to dryness on the water-bath and extracted with chloroform (P. Cazeneuve, _Bull. de la soc. chim. de Paris_, 1876-1877, 27, p. 199). Synthetically it may be prepared by the methylation of silver theobromine and silver theophyllin or by boiling heteroxanthine with methyl iodide and potash. E. Fischer and L. Ach (_Berichte_, 1895, 28, p. 3135) have synthesized it from dimethyl alloxan, whilst W. Traube (_Berichte_, 1900, 33, p. 3435) has obtained it from 1.3 diamethyl 4.5 diamino 2.6 dioxypyrimidine. On the constitution of caffeine see PURIN and also E. Fischer (_Annalen_, 1882, 215, p. 253).

Caffeine crystallizes in long silky needles, which are slightly soluble in cold water. It becomes anhydrous at 100°C. and melts at 234° to 235°C. It has a faint bitter taste and gives salts with mineral acids. On oxidation with nitric acid caffeine gives cholesterophane (dimethyl parabanic acid), but if chlorine water be used as the oxidant, then it yields monomethyl urea and dimethyl alloxan (E. Fischer).

CAFFIERI, JACQUES (1678-1755), French worker in metal, the most famous member of a family several of whom distinguished themselves in plastic art, was the fifth son of Philippe Caffieri (1634-1716), a decorative sculptor, who, after serving Pope Alexander VII., entered the service of Louis XIV. in 1660. An elder son of Philippe, François Charles (1667-1721), was associated with him. As a _fondeur ciseleur_, however, the renown of the house centred in Jacques, though it is not always easy to distinguish between his own work and that of his son Philippe (1714-1777). A large proportion of his brilliant achievement as a designer and chaser in bronze and other metals was executed for the crown at Versailles, Fontainebleau, Compiègne, Choisy and La Muette, and the crown, ever in his debt, still owed him money at his death. Jacques and his son Philippe undoubtedly worked together in the "Appartement du Dauphin" at Versailles, and although much of their contribution to the palace has disappeared, the decorations of the marble chimney-piece still remain. They belong to the best type of the Louis XV. style--vigorous and graceful in design, they are executed with splendid skill. It is equally certain that father and son worked together upon the gorgeous bronze case of the famous astronomical clock made by Passement and Danthiau for Louis XV. between 1749 and 1753. The form of the case has been much criticized, and even ridiculed, but the severest critics in that particular have been the readiest to laud the boldness and freedom of the motives, the jewel-like finish of the craftsmanship, the magnificent dexterity of the master-hand. The elder Caffieri was, indeed, the most consummate practitioner of the _style rocaille_, which he constantly redeemed from its mannered conventionalism by the ease and mastery with which he treated it. From the studio in which he and his son worked side by side came an amazing amount of work, chiefly in the shape of those gilded bronze mounts which in the end became more insistent than the pieces of furniture which they adorned. Little of his achievement was ordinary; an astonishingly large proportion of it is famous. There is in the Wallace collection (Hertford House, London) a commode from the hand of Jacques Caffieri in which the brilliance and spontaneity, the sweeping boldness and elegance of line that mark his style at its best, are seen in a perfection hardly exceeded in any other example. Also at Hertford House is the exceptionally fine lustre which was a wedding present from Louis XV. to Louise Elizabeth of France. After Jacques' death his son Philippe continued to work for the crown, but had many private clients. He made a great cross and six candlesticks for the high altar of Notre Dame, which disappeared in the revolution, but similar work for Bayeux cathedral still exists. A wonderful enamelled toilet set which he executed for the Princess of Asturias has also disappeared. Philippe's style was gradually modified into that which prevailed in the third quarter of the 18th century, since by 1777, when he died, the taste for the magnificent mounts of his early days had passed away. Like his father, he drew large sums from the crown, usually after giving many years' credit, while many other years were needed by his heirs to get in the balance of the royal indebtedness. Philippe's younger brother, Jean Jacques Caffieri (1725-1792), was a sculptor, but was sufficiently adept in the treatment of metals to design the fine _rampe d'escalier_ which still adorns the Palais Royal.

CAFTAN, or KAFTAN (a Turkish word, also in use in Persia), a tunic or under-dress with long hanging sleeves, tied with a girdle at the waist, worn in the East by persons of both sexes. The caftan was worn by the upper and middle classes in Russia till the time of Peter the Great, when it was generally discarded.

CAGLI, a town and (with Pergola) an episcopal see of the Marches, Italy, in the province of Pesaro and Urbino, 18 m. S. of the latter town by rail, and 830 ft. above sea-level. Pop. (1901) of town, 4628; commune, 12,533. The church of S. Domenico contains a good fresco (Madonna and saints) by Giovanni Santi, the father of Raphael. The citadel of the 15th century, constructed by Francesco di Giorgio Martini of Siena, is on the S.E. of the modern town. Cagli occupies the site of an ancient _vicus_ (village) on the Via Flaminia, which seems to have borne the name Cale, 24 m. N. of Helvillum (mod. _Sigillo_) and 18 m. S.W. of Forum Sempronii (mod. _Fossombrone_). Below the town to the north is a single arched bridge of the road, the arch having the span of 38¼ ft. (See G. Mochi, _Storia di Cagli_, Cagli, 1878.) About 5 m. to the N.N.W. of Cagli and 2½ m. W. of the Via Flaminia at the mod. _Acqualagna_ is the site of an ancient town; the place is now called _piano di Valeria_, and is scattered with ruins. Inscriptions show that this was a Roman _municipium_, perhaps Pitinum Mergens (_Corp. Inscr. Lat._ xi. [Berlin, 1901] p. 876). Three miles north of Acqualagna the Via Flaminia, which is still in use as the modern high-road, traverses the Furlo Pass, a tunnel about 40 yds. long, excavated by Vespasian in A.D. 77, as an inscription at the north end records. There is another tunnel at lower level, which belongs to an earlier date; this seems to have been in use till the construction of the Roman road, which at first ran round the rock on the outside, until Vespasian cut the tunnel. In repairing the modern road just outside the south entrance to the tunnel, a stratum of carbonized corn, beans, &c., and a quantity of burnt wood, stones, tiles, pottery, &c., was found under and above the modern road, for a distance of some 500 yds. This débris must have belonged to the castle of Petra Pertusa, burned by the Lombards in 570 or 571 on their way to Rome. The castle itself is mentioned by Procopius (_Bell. Goth._ ii. 11, iii. 6, iv. 28, 34). Here also was found the inscription of A.D. 295, relating to the measures taken to suppress brigandage in these parts. (See APENNINES.)

See A. Vernarecci in _Notizie degli Scavi_, 1886, 411 (cf. _ibid._ 227); _Corp. Inscr. Lat._ (Berlin, 1901), Nos. 6106, 6107.

CAGLIARI (anc. _Carales_), the capital of the island of Sardinia, an archiepiscopal see, and the chief town of the province of Cagliari, which embraces the southern half of the island. It is 270 m. W.S.W. of Naples, and 375 m. south of Genoa by sea. Pop. (1900) of town, 48,098; of commune, 53,057. It is finely situated at the northern extremity of the Gulf of Cagliari, in the centre of the south coast of the island. The medieval town occupies a long narrow hill running N. and S. with precipitous [v.04 p.0946] cliffs on the E. and W. which must have been the ancient acropolis, but the modern town, like the Roman town before it, extends to the slopes of the hill and to the low ground by the sea. On each side of the town are lagoons. That of S. Gilla on the W., which produces fish in abundance, was originally an open bay. That of Molentargius on the E. has large saltpans. The upper town still retains in part its fortifications, including the two great towers at the two extremities, called the Torre dell' Elefante (S.) and the Torre di S. Pancrazio (N.), both erected by the Pisans, the former in 1307, the latter in 1305. The Torre di S. Pancrazio at the highest point (367 ft. above sea-level) commands a magnificent view. Close to it is the archaeological museum, the most important in the island. To the north of it are the modern citadel and the barracks, and beyond, a public promenade. The narrow streets run from north to south for the whole length of the upper town. On the edge of the cliffs on the E. is the cathedral, built in 1257-1312 by the Pisans, and retaining two of the original transept doors. The pulpit of the same period is also fine: it now stands, divided into two, on each side of the entrance, while the lions which supported it are on the balustrade in front of the cathedral (see E. Brunelli in _L'Arte_, Rome, 1901, 59; D. Scano, _ibid._ 204). Near the sacristy are also some Gothic chapels of the Aragonese period. The church was, however, remodelled in 1676, and the interior is baroque. Two fine silver candelabra, the tabernacle and the altar front are of the 17th century; and the treasury also contains some good silver work. (See D. Scano in _Bolletino d'Arte_, February 1907, p. 14; and E. Brunelli in _L'Arte_, 1907, p. 47.) The crypt contains three ancient sarcophagi. The façade, in the baroque style, was added in 1703. The university, a little farther north, the buildings of which were erected in 1764, has some 240 students. At the south extremity of the hill, on the site of the bastian of south Caterina, a large terrace, the Passeggiata Umberto Primo, has been constructed: it is much in use on summer evenings, and has a splendid view. Below it are covered promenades, and from it steps descend to the lower town, the oldest part of which (the so-called Marina), sloping gradually towards the sea, is probably the nucleus of the Roman _municipium_, while the quarter of Stampace lies to the west, and beyond it again the suburb of Sant' Avendrace. The northern portion of this, below the castle hill, is the older, while the part near the shore consists mainly of modern buildings of no great interest. To the east of the castle hill and the Marina is the quarter of Villanova, which contains the church of S. Saturnino, a domed church of the 8th century with a choir of the Pisan period. The harbour of Cagliari (along the north side of which runs a promenade called the Via Romo) is a good one, and has a considerable trade, exporting chiefly lead, zinc and other minerals and salt, the total annual value of exports amounting to nearly 1½ million sterling in value. The Campidano of Cagliari, the plain which begins at the north end of the lagoon of S. Gilla, is very fertile and much cultivated, as is also the district to the east round Quarto S. Elena, a village with 8459 inhabitants (1901). The national costumes are rarely now seen in the neighbourhood of Cagliari, except at certain festivals, especially that of S. Efisio (May 1-4) at Pula (see NORA). The methods of cultivation are primitive: the curious water-wheels, made of brushwood with pots tied on to them, and turned by a blindfolded donkey, may be noted. The ox-carts are often made with solid wheels, for greater strength. Prickly pear (_opuntia_) hedges are as frequent as in Sicily. Cagliari is considerably exposed to winds in winter, while in summer it is almost African in climate. The aqueduct was constructed in quite recent times, rain-water having previously given the only supply. The main line of railway runs north to Decimomannu (for Iglesias), Oristano, Macomer and Chilivani (for Golfo degli Aranci and Sassari); while another line (narrow-gauge) runs to Mandas (for Sorgono and Tortoli). There is also a tramway to Quarto S. Elena.

In A.D. 485 the whole of Sardinia was taken by the Vandals from Africa; but in 533 it was retaken by Justinian. In 687 Cagliari rose against the East Roman emperors, under Gialetus, one of the citizens, who made himself king of the whole island, his three brothers becoming governors of Torres (in the N.W.), Arborea (in the S.W.) and Gallura (in the N.E. of the island). The Saracens devastated it in the 8th century, but were driven out, and the island returned to the rule of kings, until they fell in the 10th century, their place being taken by four "judges" of the four provinces, Cagliari, Torres, Arborea and Gallura. In the 12th century Musatto, a Saracen, established himself in Cagliari, but was driven out with the help of the Pisans and Genoese. The Pisans soon acquired the sovereignty over the whole island with the exception of Arborea, which continued to be independent. In 1297 Boniface VIII. invested the kings of Aragon with Sardinia, and in 1326 they finally drove the Pisans out of Cagliari, and made it the seat of their government. In 1348 the island was devastated by the plague described by Boccaccio. It was not until 1403 that the kings of Aragon were able to conquer the district of Arborea, which, under the celebrated Eleonora (whose code of laws--the so-called _Carta de Logu_--was famous), offered a heroic resistance. In 1479 the native princes were deprived of all independence. The island remained in the hands of Spain until the peace of Utrecht (1714), by which it was assigned to Austria. In 1720 it was ceded by the latter, in exchange for Sicily, to the duke of Savoy, who assumed the title of king of Sardinia (Cagliari continuing to be the seat of government), and this remained the title of the house of Savoy until 1861. Cagliari was bombarded by the French fleet in 1793, but Napoleon's attempt to take the island failed.

CAGLIOSTRO, ALESSANDRO, COUNT (1743-1793), Italian alchemist and impostor, was born at Palermo on the 8th of June 1743. Giuseppe Balsamo--for such was the "count's" real name--gave early indications of those talents which afterwards gained for him so wide a notoriety. He received the rudiments of his education at the monastery of Caltagirone in Sicily, but was expelled from it for misconduct and disowned by his relations. He now signalized himself by his dissolute life and the ingenuity with which he contrived to perpetrate forgeries and other crimes without exposing himself to the risk of detection. Having at last got into trouble with the authorities he fled from Sicily, and visited in succession Greece, Egypt, Arabia, Persia, Rhodes--where he took lessons in alchemy and the cognate sciences from the Greek Althotas--and Malta. There he presented himself to the grand master of the Maltese order as Count Cagliostro, and curried favour with him as a fellow alchemist, for the grand master's tastes lay in the same direction. From him he obtained introductions to the great houses of Rome and Naples, whither he now hastened. At Rome he married a beautiful but unprincipled woman, Lorenza Feliciani, with whom he travelled, under different names, through many parts of Europe. It is unnecessary to recount the various infamous means which he employed to pay his expenses during these journeys. He visited London and Paris in 1771, selling love-philtres, elixirs of youth, mixtures for making ugly women beautiful, alchemistic powders, &c., and deriving large profits from his trade. After further travels on the continent he returned to London, where he posed as the founder of a new system of freemasonry, and was well received in the best society, being adored by the ladies. He went to Germany and Holland once more, and to Russia, Poland, and then again to Paris, where, in 1785, he was implicated in the affair of the Diamond Necklace (_q.v._); and although Cagliostro escaped conviction by the matchless impudence of his defence, he was imprisoned for other reasons in the Bastille. On his liberation he visited England once more, where he succeeded well at first; but was ultimately outwitted by some English lawyers, and confined for a while in the Fleet prison. Leaving England, he travelled through Europe as far as Rome, where he was arrested in 1789. He was tried and condemned to death for being a heretic, but the sentence was commuted to perpetual imprisonment, while his wife was immured in a convent. He died in the fortress prison of San Leo in 1795.

The best account of the life, adventures and character of Giuseppe Balsamo is contained in Carlyle's _Miscellanies_. Dumas's novel, _Memoirs of a Physician_, is founded on his adventures; see also a [v.04 p.0947] series of papers in the _Dublin University Magazine_, vols. lxxviii. and lxxix.; _Memorial, or Brief for Cagliostro in the Cause of Card. de Rohan_, &c.

CAGNIARD DE LA TOUR, CHARLES (1777-1859), French engineer and physicist, was born in Paris on the 31st of March 1777, and after attending the École Polytechnique became one of the _ingénieurs géographiques_. He was made a baron in 1818, and died in Paris on the 5th of July 1859. He was the author of numerous inventions, including the cagniardelle, a blowing machine, which consists essentially of an Archimedean screw set obliquely in a tank of water in such a way that its lower end is completely and its upper end partially immersed, and operated by being rotated in the opposite direction to that required for raising water. In acoustics he invented, about 1819, the improved siren which is known by his name, using it for ascertaining the number of vibrations corresponding to a sound of any particular pitch, and he also made experiments on the mechanism of voice-production. In course of an investigation in 1822-1823 on the effects of heat and pressure on certain liquids he found that for each there was a certain temperature above which it refused to remain liquid but passed into the gaseous state, no matter what the amount of pressure to which it was subjected, and in the case of water he determined this critical temperature, with a remarkable approach to accuracy, to be 362°C. He also studied the nature of yeast and the influence of extreme cold upon its life.

CAGNOLA, LUIGI, MARCHESE (1762-1833), Italian architect, was born on the 9th of June 1762 in Milan. He was sent at the age of fourteen to the Clementine College at Rome, and afterwards studied at the university of Pavia. He was intended for the legal profession, but his passion for architecture was too strong, and after holding some government posts at Milan, he entered as a competitor for the construction of the Porta Orientale. His designs were commended, but were not selected on account of the expense their adoption would have involved. From that time Cagnola devoted himself entirely to architecture. After the death of his father he spent two years in Verona and Venice, studying the architectural structures of these cities. In 1806 he was called upon to erect a triumphal arch for the marriage of Eugene Beauharnais with the princess of Bavaria. The arch was of wood, but was of such beauty that it was resolved to carry it out in marble. The result was the magnificent Arco della Pace in Milan, surpassed in dimensions only by the Arc de l'Étoile at Paris. Among other works executed by Cagnola are the Porta di Marengo at Milan, the campanile at Urgnano, and the chapel of Santa Marcellina in Milan. He died on the 14th of August 1833, five years before the completion of the Arco del Sempione, which he designed for his native city.

CAGOTS, a people found in the Basque provinces, Béarn, Gascony and Brittany. The earliest mention of them is in 1288, when they appear to have been called Christiens or Christianos. In the 16th century they had many names, Cagots, Gahets, Gafets in France; Agotes, Gafos in Spain; and Cacons, Cahets, Caqueux and Caquins in Brittany. During the middle ages they were popularly looked upon as cretins, lepers, heretics and even as cannibals. They were shunned and hated; were allotted separate quarters in towns, called _cagoteries_, and lived in wretched huts in the country distinct from the villages. Excluded from all political and social rights, they were only allowed to enter a church by a special door, and during the service a rail separated them from the other worshippers. Either they were altogether forbidden to partake of the sacrament, or the holy wafer was handed to them on the end of a stick, while a receptacle for holy water was reserved for their exclusive use. They were compelled to wear a distinctive dress, to which, in some places, was attached the foot of a goose or duck (whence they were sometimes called _Canards_). And so pestilential was their touch considered that it was a crime for them to walk the common road barefooted. The only trades allowed them were those of butcher and carpenter, and their ordinary occupation was wood-cutting. Their language is merely a corrupt form of that spoken around them; but a Teutonic origin seems to be indicated by their fair complexions and blue eyes. Their crania have a normal development; their cheek-bones are high; their noses prominent, with large nostrils; their lips straight; and they are marked by the absence of the auricular lobules.

The origin of the Cagots is undecided. Littré defines them as "a people of the Pyrenees affected with a kind of cretinism." It has been suggested that they were descendants of the Visigoths, and Michael derives the name from _caas_ (dog) and _Goth_. But opposed to this etymology is the fact that the word _cagot_ is first found in the _for_ of Béarn not earlier than 1551. Marca, in his _Histoire de Béarn_, holds that the word signifies "hunters of the Goths," and that the Cagots are descendants of the Saracens. Others made them descendants of the Albigenses. The old MSS. call them Chrétiens or Chrestiaas, and from this it has been argued that they were Visigoths who originally lived as Christians among the Gascon pagans. A far more probable explanation of their name "Chrétiens" is to be found in the fact that in medieval times all lepers were known as _pauperes Christi_, and that, Goths or not, these Cagots were affected in the middle ages with a particular form of leprosy or a condition resembling it. Thus would arise the confusion between Christians and Cretins. To-day their descendants are not more subject to goitre and cretinism than those dwelling around them, and are recognized by tradition and not by features or physical degeneracy. It was not until the French Revolution that any steps were taken to ameliorate their lot, but to-day they no longer form a class, but have been practically lost sight of in the general peasantry.

CAHER (or CAHIR), a market-town of Co. Tipperary, Ireland, in the south parliamentary division, beautifully situated on the river Suir at the foot of the Galtee Mountains. Pop. (1901) 2058. It stands midway between Clonmel and Tipperary town on the Waterford and Limerick line of the Great Southern and Western railway, 124 m. S.W. from Dublin. It is the centre of a rich agricultural district, and there is some industry in flour-milling. Its name (_cathair_, stone fortress) implies a high antiquity and the site of the castle, picturesquely placed on an island in the river, was occupied from very early times. Here was a fortress-palace of Munster, originally called _Dun-iasgach_, the suffix signifying "abounding in fish." The present castle dates from 1142, being built by O'Connor, lord of Thomond, and is well restored. It was besieged during the wars of 1599 and 1647, and by Cromwell. Among the fine environs of the town the demesne of Caher Park is especially noteworthy. The Mitchelstown stalactite caverns, 10 m. S.W., and the finely-placed Norman castle of Ardfinnan, on a precipitous crag 6 m. down the Suir, are other neighbouring features of interest, while the Galtee Mountains, reaching in Galtymore a height of 3015 ft., command admirable prospects.

CAHITA, a group of North American Indians, mainly of the Mayo and Yaqui tribes, found chiefly in Mexico, belonging to the Piman family, and numbering some 40,000.

CAHOKIA, the name of a North American Indian tribe of the Illinois confederacy, and of their mission station, near St Louis. The "Cahokia mound" there (a model of which is in the Peabody Museum, Cambridge, Mass.) is interesting as the largest pre-historic earth-work in America.

CAHORS, a city of south-western France, capital of the department of Lot, 70 m. N. of Toulouse, on the railway between that city and Limoges. Pop. (1906) 10,047. Cahors stands on the right bank of the river Lot, occupying a rocky peninsula formed by a bend in the stream. It is divided into two portions [v.04 p.0948] by the Boulevard Gambetta, which runs from the Pont Louis Philippe on the south to within a short distance of the fortified wall of the 14th and 15th centuries enclosing the town on the north. To the east lies the old town, with its dark narrow streets and closely-packed houses; west of the Boulevard a newer quarter, with spacious squares and promenades, stretches to the bank of the river. Cahors communicates with the opposite shore by three bridges. One of these, the Pont Valentré to the west of the town, is the finest fortified bridge of the middle ages in France. It is a structure of the early 14th century, restored in the 19th century, and is defended at either end by high machicolated towers, another tower, less elaborate, surmounting the centre pier. The east bridge, the Pont Neuf, also dates from the 14th century. The cathedral of St Étienne stands in the heart of the old town. It dates from the 12th century, but was entirely restored in the 13th century. Its exterior, for the most part severe in appearance, is relieved by some fine sculpture, that of the north portal being especially remarkable. The nave, which is without aisles, is surmounted by two cupolas; its interior is whitewashed and plain in appearance, while the choir is decorated with medieval paintings. Adjoining the church to the south-east there are remains of a cloister built from 1494 to 1509. St Urcisse, the chief of the other ecclesiastical buildings, stands near the cathedral. Dating from the 12th and 13th centuries, it preserves Romanesque capitals recarved in the 14th century. The principal of the civil buildings is the palace of Pope John XXII., built at the beginning of the 14th century; a massive square tower is still standing, but the rest is in ruins. The residence of the seneschals of Quercy, a building of the 14th to the 17th centuries, known as the Logis du Roi, also remains. The chief of the old houses, of which there are many in Cahors, is one of the 15th century, known as the Maison d'Henri IV. Most of the state buildings are modern, with the exception of the prefecture which occupies the old episcopal palace, and the old convent and the Jesuit college in which the Lycée Gambetta is established. The Porte de Diane is a large archway of the Roman period, probably the entrance to the baths. Of the commemorative monuments, the finest is that erected in the Place d'Armes to Gambetta, who was a native of the town. There is also a statue of the poet Clément Marot, born at Cahors in 1496. Cahors is the seat of a bishopric, a prefect and a court of assizes. It has tribunals of first instance and of commerce, a chamber of commerce and a branch of the Bank of France. There are also training colleges, a lycée, a communal college for girls, an ecclesiastical seminary, a library, museum and hospital. The manufacture of farm implements, tanning, wool-spinning, metal-founding, distilling and the preparation of _pâté de foie gras_ and other delicacies are carried on. Wine, nuts, oil of nuts, tobacco, truffles and plums are leading articles of commerce.

_History._--Before the Roman conquest, Cahors, which grew up near the sacred fountain of Divona (now known as the Fontaine des Chartreux), was the capital of the Cadurci. Under the Romans it enjoyed a prosperity partly due to its manufacture of cloth and of mattresses, which were exported even to Rome. The first bishop of Cahors, St Genulfus, appears to have lived in the 3rd century. In the middle ages the town was the capital of Quercy, and its territory until after the Albigensian Crusade was a fief of the counts of Toulouse. The seigniorial rights, including that of coining money, belonged to the bishops. In the 13th century Cahors was a financial centre of much importance owing to its colony of Lombard bankers, and the name _cahorsin_ consequently came to signify "banker" or "usurer." At the beginning of the century a commune was organized in the town. Its constant opposition to the bishops drove them, in 1316, to come to an arrangement with the French king, by which the administration of the town was placed almost entirely in the hands of royal officers, king and bishop being co-seigneurs. This arrangement survived till the Revolution. In 1331 Pope John XXII., a native of Cahors, founded there a university, which afterwards numbered Jacques Cujas among its teachers and François Fénelon among its students. It flourished till 1751, when it was united to its rival the university of Toulouse. During the Hundred Years' War, Cahors, like the rest of Quercy, consistently resisted the English occupation, from which it was relieved in 1428. In the 16th century it belonged to the viscounts of Béarn, but remained Catholic and rose against Henry of Navarre who took it by assault in 1580. On his accession Henry IV. punished the town by depriving it of its privileges as a wine-market; the loss of these was the chief cause of its decline.

CAIATIA (mod. _Caiazzo_), an ancient city of Campania, on the right bank of the Volturnus, 11 m. N.E. of Capua, on the road between it and Telesia. It was already in the hands of the Romans in 306 B.C., and since in the 3rd century B.C. it issued copper coins with a Latin legend it must have had the _civitas sine suffragio_. In the Social War it rebelled from Rome, and its territory was added to that of Capua by Sulla. In the imperial period, however, we find it once more a _municipium_. Caiatia has remains of Cyclopean walls, and under the Piazza del Mercato is a large Roman cistern, which still provides a good water supply. The episcopal see was founded in A.D. 966. The place is frequently confused with Calatia (_q.v._).

CAIETAE PORTUS (mod. _Gaeta_), an ancient harbour of _Latium adiectum_, Italy, in the territory of Formiae, from which it is 5 m. S.W. The name (originally [Greek: Aiêtê]) is generally derived from the nurse of Aeneas. The harbour, owing to its fine anchorage, was much in use, but the place was never a separate town, but always dependent on Formiae. Livy mentions a temple of Apollo. The coast of the Gulf not only between Caietae Portus and Formiae, but E. of the latter also, as far as the modern Monte Scauri, was a favourite summer resort (see FORMIA). Cicero may have had villas both at Portus Caietae and at Formiae[1] proper, and the emperors certainly possessed property at both places. After the destruction of Formiae in A.D. 847 it became one of the most important seaports of central Italy (see GAETA). In the town are scanty remains of an amphitheatre and theatre: near the church of La Trinità, higher up, are remains of a large reservoir. There are also traces of an aqueduct. The promontory (548 ft.) is crowned by the tomb of Munatius Plancus, founder of Lugudunum (mod. Lyons), who died after 22 B.C. It is a circular structure of blocks of travertine 160 ft. high and 180 ft. in diameter. Further inland is the so-called tomb of L. Atratinus, about 100 ft. in diameter. Caietae Portus was no doubt connected with the Via Appia (which passed through Formiae) by a _deverticulum_. There seems also to have been a road running W.N.W. along the precipitous coast to Speluncae (mod. Sperlonga).

See E. Gesualdo _Osservazioni critiche sopra la storia della Via Appia di Pratilli_ p. 7 (Naples, 1754).

[1] The two places are sufficiently close for the one villa to have borne both names; but Mommsen (_Corp. Inscrip. Lat._ x., Berlin, 1883, p. 603) prefers to differentiate them.

CAILLIÉ (or CAILLÉ), RENÉ AUGUSTE (1799-1838), French explorer, was born at Mauzé, Poitou, in 1799, the son of a baker. The reading of _Robinson Crusoe_ kindled in him a love of travel and adventure, and at the age of sixteen he made a voyage to Senegal whence he went to Guadeloupe. Returning to Senegal in 1818 he made a journey to Bondu to carry supplies to a British expedition then in that country. Ill with fever he was obliged to go back to France, but in 1824 was again in Senegal with the fixed idea of penetrating to Timbuktu. He spent eight months with the Brakna "Moors" living north of Senegal river, learning Arabic and being taught, as a convert, the laws and customs of Islam. He laid his project of reaching Timbuktu before the governor of Senegal, but receiving no encouragement went to Sierra Leone where the British authorities made him superintendent of an indigo plantation. Having saved £80 he joined a Mandingo caravan going inland. He was dressed as a Mussulman, and gave out that he was an Arab from Egypt who had been carried off by the French to Senegal and was desirous of regaining his own country. Starting from Kakundi near Boké on the Rio Nunez on 19th of April 1827, he travelled east along the hills of Futa Jallon, passing the head streams of the Senegal and crossing the Upper Niger at Kurussa. Still going east he came to the Kong highlands, where at a place called Timé he was detained five months by illness. Resuming his journey [v.04 p.0949] in January 1828 he went north-east and gained the city of Jenné, whence he continued his journey to Timbuktu by water. After spending a fortnight (20th April-4th May) in Timbuktu he joined a caravan crossing the Sahara to Morocco, reaching Fez on the 12th of August. From Tangier he returned to France. He had been preceded at Timbuktu by a British officer, Major Gordon Laing, but Laing had been murdered (1826) on leaving the city and Caillié was the first to accomplish the journey in safety. He was awarded the prize of £400 offered by the Geographical Society of Paris to the first traveller who should gain exact information of Timbuktu, to be compared with that given by Mungo Park. He also received the order of the Legion of Honour, a pension, and other distinctions, and it was at the public expense that his _Journal d'un voyage à Temboctou et à Jenne dans l'Afrique Centrale_, etc. (edited by E.F. Jomard) was published in three volumes in 1830. Caillié died at Badère in 1838 of a malady contracted during his African travels. For the greater part of his life he spelt his name Caillié, afterwards omitting the second "i."

See Dr Robert Brown's _The Story of Africa_, vol. i. chap. xii. (London, 1892); Goepp and Cordier, _Les Grands Hommes de France, voyageurs: René Caillé_ (Paris, 1885); E.F. Jomard, _Notice historique sur la vie et les voyages de R. Caillié_ (Paris, 1839). An English version of Caillié's _Journal_ was published in London in 1830 in two volumes under the title of _Travels through Central Africa to Timbuctoo_, &c.

CAIN, in the Bible, the eldest son of Adam and Eve (Gen. iv.), was a tiller of the ground, whilst his younger brother, Abel, was a keeper of sheep. Enraged because the Lord accepted Abel's offering, and rejected his own, he slew his brother in the field (see ABEL). For this a curse was pronounced upon him, and he was condemned to be a "fugitive and a wanderer" on the earth, a mark being set upon him "lest any finding him should kill him." He took up his abode in the land of Nod ("wandering") on the east of Eden, where he built a city, which he named after his son Enoch. The narrative presents a number of difficulties, which early commentators sought to solve with more ingenuity than success. But when it is granted that the ancient Hebrews, like other primitive peoples, had their own mythical and traditional figures, the story of Cain becomes less obscure. The mark set upon Cain is usually regarded as some tribal mark or sign analogous to the cattle marks of Bedouin and the related usages in Europe. Such marks had often a religious significance, and denoted that the bearer was a follower of a particular deity. The suggestion has been made that the name Cain is the eponym of the Kenites, and although this clan has a good name almost everywhere in the Old Testament, yet in Num. xxiv. 22 its destruction is foretold, and the Amalekites, of whom they formed a division, are consistently represented as the inveterate enemies of Yahweh and of his people Israel. The story of Cain and Abel, which appears to represent the nomad life as a curse, may be an attempt to explain the origin of an existence which in the eyes of the settled agriculturist was one of continual restlessness, whilst at the same time it endeavours to find a reason for the institution of blood-revenge on the theory that at some remote age a man (or tribe) had killed his brother (or brother tribe). Cain's subsequent founding of a city finds a parallel in the legend of the origin of Rome through the swarms of outlaws and broken men of all kinds whom Romulus attracted thither. The list of Cain's descendants reflects the old view of the beginnings of civilization; it is thrown into the form of a genealogy and is parallel to Gen. v. (see GENESIS). It finds its analogy in the Phoenician account of the origin of different inventions which Eusebius (_Praep. Evang._ i. 10) quotes from Philo of Byblus (Gebal), and probably both go back to a common Babylonian origin.

On this question, see Driver, _Genesis_ (Westminster Comm., London, 1904), p. 80 seq.; A. Jeremias, _Alte Test. im Lichte d. Alten Orients_ (Leipzig, 1906), pp. 220 seq.; also ENOCH, LAMECH. On the story of Cain, see especially Stade, _Akademische Reden_, pp. 229-273; Ed. Meyer, _Israeliten_, pp. 395 sqq.; A.R. Gordon, _Early Trad. Genesis_ (Index). Literary criticism (see Cheyne, _Encycl. Bib._ col. 620-628, and 4411-4417) has made it extremely probable that Cain the nomad and outlaw (Gen. iv. 1-16) was originally distinct from Cain the city-builder (vv. 17 sqq.). The latter was perhaps regarded as a "smith," cp. v. 22 where Tubal-cain is the "father" of those who work in bronze (or copper). That the Kenites, too, were a race of metal-workers is quite uncertain, although even at the present day the smiths in Arabia form a distinct nomadic class. Whatever be the meaning of the name, the words put into Eve's mouth (v. 1) probably are not an etymology, but an assonance (Driver). It is noteworthy that Kenan, son of Enosh ("man," Gen. v. 9), appears in Sabaean inscriptions of South Arabia as the name of a tribal-god.

A Gnostic sect of the 2nd century was known by the name of Cainites. They are first mentioned by Irenaeus, who connects them with the Valentinians. They believed that Cain derived his existence from the superior power, and Abel from the inferior power, and that in this respect he was the first of a line which included Esau, Korah, the Sodomites and Judas Iscariot.
