CHARNOCK (or Chernock), ROBERT (c.1663-1696), English conspirator, belonged to a Warwickshire family, and was educated at Magdalen College, Oxford, becoming a fellow of his college and a Roman Catholic priest. When in 1687 the dispute arose between James II. and the fellows of Magdalen over the election of a president Charnock favoured the first royal nominee, Anthony Farmer, and also the succeeding one, Samuel Parker, bishop of Oxford. Almost alone among the fellows he was not driven out in November 1687, and he became dean and then vice-president of the college under the new regime, but was expelled in October 1688. Residing at the court of the Stuarts in France, or conspiring in England, Charnock and Sir George Barclay appear to have arranged the details of the unsuccessful attempt to kill William III. near Turnham Green in February 1696, Barclay escaped, but Charnock was arrested, was tried and found guilty, and was hanged on the 18th of March 1696.
CHARNOCKITE, a series of foliated igneous rocks of wide distribution and great importance in India, Ceylon, Madagascar and Africa. The name was given by Dr T.H. Holland from the fact that the tombstone of Job Charnock, the founder of Calcutta, is made of a block of this rock. The charnockite series includes rocks of many different types, some being acid and rich in quartz and microcline, others basic and full of pyroxene and olivine, while there are also intermediate varieties corresponding mineralogically to norites, quartz-norites and diorites. A special feature, recurring in many members of the group, is the presence of strongly pleochroic, reddish or green hypersthene. Many of the minerals of these rocks are “schillerized,” as they contain minute platy or rod-shaped enclosures, disposed parallel to certain crystallographic planes or axes. The reflection of light from the surfaces of these enclosures gives the minerals often a peculiar appearance, e.g. the quartz is blue and opalescent, the felspar has a milky shimmer like moonshine, the hypersthene has a bronzy metalloidal gleam. Very often the different rock types occur in close association as one set forms bands alternating with another set, or veins traversing it, and where one facies appears the others also usually are found. The term charnockite consequently is not the name of a rock, but of an assemblage of rock types, connected in their origin because arising by differentiation of the same parent magma. The banded structure which these rocks commonly present in the field is only in a small measure due to crushing, but is to a large extent original, and has been produced by fluxion in a viscous crystallizing intrusive magma, together with differentiation or segregation of the mass into bands of different chemical and mineralogical composition. There have also been, of course, earth movements acting on the solid rock at a later time and injection of dikes both parallel to and across the primary foliation. In fact, the history of the structures of the charnockite series is the history of the most primitive gneisses in all parts of the world, for which we cannot pretend to have as yet any thoroughly satisfactory explanations to offer. A striking fact is the very wide distribution of rocks of this group in the southern hemisphere; but they also, or rocks very similar to them, occur in Norway, France, Germany, Scotland and North America, though in these countries they have been mostly described as pyroxene granulites, pyroxene gneisses, anorthosites, &c. They are usually regarded as being of Archean age (pre-Cambrian), and in most cases this can be definitely proved, though not in all. It is astonishing to find that in spite of their great age their minerals are often in excellent preservation. In India they form the Nilgiri Hills, the Shevaroys and part of the Western Ghats, extending southward to Cape Comorin and reappearing in Ceylon. Although they are certainly for the most part igneous gneisses (or orthogneisses), rocks occur along with them, such as marbles, scapolite limestones, and corundum rocks, which were probably of sedimentary origin.

CHARNWOOD FOREST, an upland tract in the N.-W. of Leicestershire, England. It is undulating, rocky, picturesque, and in great part barren, though there are some extensive tracts of woodland; its elevation is generally 600 ft. and upwards, the area exceeding this height being about 6100 acres. The loftiest point, Bardon Hill, is 912 ft. On its western flank lies a coalfield, with Coalville and other mining towns, and granite and hone-stones are worked.
CHAROLLES, a town of east-central France, capital of an arrondissement in the department of Saône-et-Loire, situated at the confluence of the Semence and the Arconce, 39 m. W.N.W. of Mâcon on the Paris-Lyon railway. Pop. (1906) 3228. It has a sub-prefecture, tribunals of primary instance and commerce, and a communal college. There are stone quarries in the vicinity; the town manufactures pottery, and is the centre for trade in the famous breed of Charolais cattle and in agricultural products. The ruins of the castle of the counts of Charolais occupy the summit of a hill in the immediate vicinity of the town. Charolles was the capital of Charolais, an old division of France, which from the early 14th century gave the title of count to its possessors. In 1327 the countship passed by marriage to the house of Armagnac, and in 1390 it was sold to Philip of Burgundy. After the death of Charles the Bold, who in his youth had borne the title of count of Charolais, it was seized by Louis XI. of France, but in 1493 it was ceded by Charles VIII. to Maximilian of Austria, the representative of the Burgundian family. Ultimately passing to the Spanish kings, it became for a considerable period an object of dispute between France and Spain, until at length in 1684 it was assigned to the great Condé, a creditor of the king of Spain. It was united to the French crown in 1771.
CHARON, in Greek mythology, the son of Erebus and Nyx (Night). It was his duty to ferry over the Styx (or Acheron) those souls of the deceased who had duly received the rites of burial, in payment for which service he received an obol, which was placed in the mouth of the corpse. It was only exceptionally that he carried living passengers (Aeneid, vi. 295 ff). As ferryman of the dead he is not mentioned in Homer or Hesiod, and in this character is probably of Egyptian origin. He is represented as a morose and grisly old man in a black sailor’s cape. By the Etruscans he was also supposed to be a kind of executioner of the powers of the nether world, who, armed with an enormous hammer, was associated with Mars in the slaughter of battle. Finally he came to be regarded as the image of death and the world below. As such he survives in the Charos or Charontas of the modern Greeks—a black bird which darts down upon its prey, or a winged horseman who fastens his victims to the saddle and bears them away to the realms of the dead.
