SERPENTINE  , a See also:

mineral which, in a massive and impure See also:form, occurs on a large See also:scale as a See also:rock, and being commonly of variegated See also:colour, is often cut and polished, like See also:marble, for use as a decorative See also:stone . It is generally held that the name was suggested by the fancied resemblance of the dark mottled See also:green stone to the skin of a See also:serpent, but it may possibly refer to some reputed virtue of the stone as a cure for snake-bite . Serpentine was probably, at least in See also:part, the XiOoc o irns of Dioscorides and the See also:ophites of See also:Pliny; and this name appears in a latinized form as the serpentaria of G . See also:Agricola, See also:writing in . the 16th See also:century, and as the lapis serpentinus and naarmor serpentinum of other See also:early writers . See also:Italian sculptors have sometimes termed it ranochia in allusion to its resemblance to the skin of a See also:frog . Although popularly called a " marble," serpentine is essentially different from any See also:kind of See also:limestone, in that it is a See also:magnesium silicate, associated however, with more or less ferrous silicate . Analyses show that the mineral contains H4Mg3Si2O9, and if the See also:water be regarded as constitutional the See also:formula may be written Mg2(SiO4)2H3(MgOH) . Serpentine occurs massive, fibrous, lamellar or granular, but never crystallized . See also:Fine pseudomorphs having the form of See also:olivine, but the See also:composition of serpentine, are known from Snarum in Buskerud, See also:Norway, the crystals revealing their See also:character by containing an occasional See also:kernel of the See also:original mineral . The alteration of rocks See also:rich in olivine has given rise to much of the serpentine occurring as rock-masses . (see See also:PERI-ooTITE) . Studied microscopically, the See also:change is seen to proceed from the See also:surface and from the irregular cracks of the. olivine, producing See also:fibres of serpentine .

The See also:

iron of the olivine passes more or less completely into the ferric See also:state, giving rise to grains of See also:magnetite, which form a See also:black dust, and may ultimately yield scales of See also:haematite or See also:limonite . Considerable increase of See also:volume generally accompanies serpentinization, and thus are produced fissures which afford passage for the agents of alteration, resulting in the formation of an irregular mesh-like structure, formed of strings of serpentine enclosing kernels of olivine in the meshes, and this olivine may itself ultimately become serpentinized . Serpentine may also be formed by the alteration of other nonaluminous ferro-magnesian silicates such as See also:enstatite, See also:augite or See also:hornblende, and in such cases it may show microscopically, a characteristic structure related to the cleavage of the, original mineral, notably See also:lozenge-shaped in the See also:case of hornblende . Many interesting pseudomorphs of serpentine were described by See also:Professor J . D . See also:Dana from the See also:Tilly See also:Foster iron-mine, near See also:Brewster, New See also:York, U.S.A., including some remarkable specimens with cubic cleavage . The purest kind of serpentine, known as " See also:noble serpentine," is generally of See also:pale greenish or yellow colour, slightly translucent, and breaking with a rather See also:bright conchoidal fracture . It occurs chiefly in granular limestone, and is often accompanied by forsterite, olivine or chondrodite . The hardness of serpentine is between 3 and 4, while the specific gravity varies from 2.5 to 2.65 . A green serpentine of the exceptional hardness of 6, ,-a—B= T formerly regarded as See also:jade, is known as bowenite, having been named by J . D . Dana after G .

T . See also:

Bowen . The original bowenite came from Smithfield, Rhode See also:Island, U.S.A., and a similar mineral was described by See also:General C . A . McMahon as occurring in See also:Afghanistan, where it is carved for ornamental purposes in the belief that it is jade (q.v.) . Many See also:common carvings regarded as jade are really serpentine, and therefore soft . Serpentine of columnar or coarsely fibrous form is termed picrolite, a name proposed by J . F . L . See also:Hausmann from the See also:Greek rtapos (See also:bitter) in allusion to the presence of See also:magnesia . The finely fibrous serpentine is called chrysotile from the lustrous yellowish colour which it usually presents (xpva6s, See also:gold; -riXos, fibre) and this variety is extensively worked, especially in See also:Canada, for use as See also:asbestos (q.v.) . In See also:order to avoid confusion between the words chrysotile and See also:chrysolite, it has been proposed by Dr J .

W . See also:

Evans that the fibrous serpentine should be distinguished as karystiolite—a modification of the See also:ancient name, taken from its occurrence near Karystos in See also:Euboea . Foliated serpentine is usually termed marmolite—a name given by G . T . See also:Nuttall, from uspsaipw (to glisten) in reference to its lustre . A thin lamellar or flaky serpentine supposed to occur in the Antigorio valley See also:north of Domodossola in See also:Piedmont is called antigorite, having been named in 184o by M . E . Schweizer, after whom a somewhat similar mineral is termed schweizerite . Antigorite has been studied by Professor T . G . See also:Bonney and See also:Miss C . See also:Raisin (Quart .

Soc., lxi., 1905, p . 690; lxiv., 19o8, p . 152) . An See also:apple-green translucent serpentine passes under the name of williamsite, having been so called by C . U . Shepard in See also:honour of its discoverer L . See also:White See also:Williams, of See also:West See also:Chester, See also:Pennsylvania, where this variety occurs . " Common serpentine " is the impure massive kind which occurs in rock-masses and is extensively worked as " serpentine-marble." It is sometimes veined with steatite, or See also:magnesite, and may contain scattered crystals of See also:diallage, See also:bronzite or bastite (an altered rhombic See also:pyroxene), which by schillerization may See also:present a metallic lustre . In See also:England the See also:chief localities of serpentine are in See also:Cornwall, especially in the See also:Lizard See also:district, where it is quarried and carved into mantelpieces, columns, vases and other ornaments . Much of it presents a rich red or See also:brown colour, often mottled and sometimes veined .

Professor Bonney has shown that it has been largely derived from olivine . Green serpentine occurs near See also:

Holyhead in See also:Anglesey . A beautiful serpentine, generally mottled red and green, with See also:veins of steatite, is found at Portsoy in See also:Banffshire, See also:Scotland, and was used for pillars in the See also:great See also:hall at See also:Versailles . Serpentine containing See also:chromite is found in the See also:Shetland Islands . The rock called " ophicalcite " consists of an intimate association of serpentine with limestone, often forming an ornamental stone which is beautifully clouded and zoned with various shades of green . It generally results from the See also:metamorphism of an impure dolomitic limestone, the impurities having crystallized as new minerals which become altered to serpentine . Pseudo-morphs of serpentine occur after forsterite . The best known serpentinous marble of the See also:British Isles occurs in See also:Connemara in See also:Galway, See also:Ireland, and passes in See also:trade under the name of " Irish green." Ophicalcites are See also:developed also in various parts of Scotland, and the green pebbles found in See also:Iona belong to this type of rock . The famous eozoonal marble of Canada is also of similar character . In See also:Saxony common serpentine is largely worked at Zoblitz near See also:Marienberg and Waldheim . The rock of Zoblitz, mentioned by G . Agricola in the 16th century, is usually of dull green or brown colour, and frequently contains dark red Bohemian See also:garnet or See also:pyrope (q.v.) .

It was used in the See also:

mausoleum of See also:Prince See also:Albert at See also:Frogmore, See also:Windsor, and in See also:Abraham See also:Lincoln's See also:monument at See also:Springfield, See also:Illinois, U.S.A . See also:Italy is rich in serpentine, the best-known being the verde di See also:Prato, which has been quarried for centuries at Monteferrato near Prato in See also:Tuscany, and has been largely used in ecclesiastical See also:architecture in See also:Florence, Prato and Pistoja . Much serpentine is found near See also:Genoa and Levanto . The verde di Pegli comes from Pegli not far from Genoa, while the verde di Genova is a brecciated serpentinouslimestone from Pietra Lavezzara . Serpentine occurs also at many localities in the See also:Apennines, in See also:Elba and in See also:Corsica . The See also:term ophiolite has been vaguely used to include not only serpentines but many other rocks associated with the Italian serpentines . Verde. antico is a brecciated serpentine with fragments of limestone, originally brought by the See also:Romans from Atrax in See also:Thessaly, and called lapis atracius . It is sometimes known as See also:veil See also:antique, or, following the old See also:French, verd antique . The term serpentine is often improperly applied to the ancient green See also:porphyry of See also:Laconia in the See also:Peloponnesus (porfido serpentino verde) . True serpentine occurs at numerous localities in the See also:Alps and in See also:France, an elegant variety being quarried at Epinal in the See also:Vosges, whilst a fine ophicalcite is worked at St Veran and Maurins, dep . Hautes-Alpes . The See also:Ronda Mountains in See also:Spain also yield serpentine .

In North See also:

America serpentine is so widely distributed that only a few localities can be specified . It is found in St See also:Lawrence See also:county, See also:Essex county and See also:Warren county, New York, and also on Staten Island; at Montville and See also:Hoboken in New See also:Jersey; at See also:Newport, Rhode Island; at See also:Newbury and See also:Newburyport, See also:Massachusetts; See also:Texas, See also:Lancaster county, and West Chester, Chester county, Pennsylvania; at many localities in See also:Vermont, and in See also:California, See also:Connecticut, See also:Georgia, See also:Maine, See also:Maryland, See also:Michigan, New See also:Mexico, North Carolina and See also:Washington . For See also:American serpentine see Stones for See also:Building and Decoration, by See also:George P . See also:Merrill (New York, 1903) ; and for serpentine asbestos see the same author's Non-metallic Minerals (New York, 1904) . (F . W . R.*) SERPENT-See also:WORSHIP . From all parts of the See also:world there is a very considerable See also:body of See also:evidence for the prominence of the serpent in See also:religion, See also:mythology and folk-See also:lore . Snake- i. prove. worship still prevails largely in See also:India, and a writer ante in in 1896 remarks that the previous See also:census showed in varying the North-West Provinces over 25,000 Naga (serpent) f0"'B• worshippers, 123,000 votaries of the snake-See also:god Guga, and, in the See also:Punjab, some 35,000 See also:special votaries of the snake godlings.1 The evidence from See also:modern India can be supplemented by the See also:medieval and ancient See also:Indian See also:sources, and, in particular, by the representations of the See also:adoration of snake-deities on the Buddhist topes of See also:Sanchi and See also:Amravati ? There we find, not indeed living serpents, but deities with serpent-symbolism, indicating a composition of various strata of religious belief, analogous to the evidence for serpent-symbolism from Babylonia, See also:Crete, See also:Greece or See also:Peru; for the higher religions have almost invariably retained in their See also:ritual and belief, sometimes with only slight modification, cruder conceptions which can still be studied in less elevated form among the See also:lower races of India, See also:Africa or America . The result is instructive when we turn to the numerous serpent myths and legends from the Old World and the New, to the stray notices in old writers, or to the fragmentary scraps of popular superstition everywhere . Modern scientific See also:research has vividly illustrated, the stereotyped nature of the human mind; there is a general similarity in the effect of similar phenomena upon See also:people at a similar See also:stage of See also:mental growth; there is an almost inherent or unconscious belief which has been transmitted through the countless ages of See also:man's See also:history .

At the same See also:

time, apart from the See also:gradual See also:evolution of religious and other conceptions there are the more incidental and artificial influences which have shaped them . Hence, our evidence for serpent-cults everywhere represents varying stages in the See also:historical development of a few related fundamental ideas which are psychologically explicable; and it is impossible to See also:deal with the subject geographically or historically . It is most useful, perhaps, to survey some of the general features of belief as an introduction to the more complex inquiries which involve a See also:consideration of other subjects over a larger See also:field . 1 See W . Crooke, The Popular Religion and Folk-lore of See also:Northern India (See also:London, 1896), ii . 122 . 2 See the elaborately illustrated See also:work of See also:James See also:Fergusson, See also:Tree and Serpent Worship, or Illustrations of Mythology and See also:Art in India (2nd ed., London, 1873) ; also M . Winternitz, der Sarpabali, ein altindischer Schlangen-cult," in Milted. d. anthrop . Gesell. of See also:Vienna, xviii . (1888), pp . 25-52, 250-264 . Both give abundant See also:information on the various features of serpent-cults .

Haunting buildings and famous ruins, gliding around pools, walls and trees, mysteriously disappearing below ground, the serpent and all its kind invariably arrested See also:

attention through its uncanny distinctiveness from See also:bird or beast . Its gliding See also:motion suggested the winding See also:river . Biting its tail it symbolized the See also:earth surrounded by the world-river . Its patient watchfulness, the See also:fascination it exerted over its victims, the easy domestication of some See also:species, and the deadliness of other's have always impressed See also:primitive minds . Its See also:swift and deadly dart was likened to the See also:lightning; equally marvellous seemed its fatal See also:power . It is little wonder that men who could tame and handle the See also:reptiles gained esteem and See also:influence . Sometimes the See also:long See also:life of the serpent and its See also:habit of changing the skin suggested ideas of See also:immortality and resurrection, and it is noteworthy that one Indian snake-festival occurs after or at the sloughing, when the sacred being is thus supposed to become purified.' A very common belief associates serpents or dragons and other monsters with the guardianship of treasure or See also:wealth; comp., e.g., 2 . See- the See also:golden apples of the See also:Hesperides, and the See also:Egyptian penis' gods Kneph and See also:Osiris, and the Indian See also:Krishna and wealth and See also:Indra . Serpents adorned with necklaces of jewels See also:wisdom. or with crowns were See also:familiar in old superstition, and the serpent with a See also:ruby in its mouth was a favourite love-token . Many stories tell of the grateful reptile which brought valuable gifts to a benefactor . According to a common Indian belief a wealthy man who See also:dies without an See also:heir returns to guard his wealth in the form of a serpent, and Italian superstition supposed that to find a serpent's skin brought See also:good See also:luck (See also:Leland).' No singular preference for jewels on the part of serpents will explain the belief, and creatures like the See also:jackdaw which have this weakness do not enjoy this prominence in folk-lore . A rationalistic explanation might be found in the connexion between the chthonic serpent and subterranean sources of wealth' Moreover, the serpent is often associated with metallurgy, and to serpent deities have been ascribed the working of metals, See also:gem-cutting and indeed culture in general .

The Aztec Quetzal-See also:

coati taught metallurgy and See also:agriculture, gave abundance of See also:maize, also wisdom and freedom from disease . The Babylonian See also:Ea, who sometimes has serpent attributes, introduced—like the American serpent Votan—knowledge and culture . The See also:half-serpent See also:Cadmus brought knowledge of mines, agriculture, and the " Cadmean " letters, while See also:Cecrops inculcated See also:laws and ways of life and was the first to establish monogamy . Although the reptile is not particularly intelligent, it has become famed for shrewdness and wisdom, whether in the See also:Garden of See also:Eden (Gen. iii . 1; 2 See also:Cor . Xi . 3) or generally (cf . Matt. x . 16) . The Ophites (q.v.) actually identified the serpent with See also:Sophia (" Wisdom "); the old See also:sage Garga, one of the fathers of Indian See also:astronomy, owed his learning to the serpent-god Sesha Naga; and the Phoenician -4pwv 'O4iwv wrote the seven tablets of See also:fate which were guarded by See also:Harmonia 4 Not only is the serpent connected with oracles, the beneficent See also:agathodaemon of See also:Phoenicia also symbolized immortality . In Babylonian myth a serpent, apparently in a well or See also:pool, deprived Gilgamesh of the plant which rejuvenated old See also:age, and if it was the rightful See also:guardian of the wonderful See also:gift, one is reminded of the See also:Hebrew See also:story, now reshaped in Gen. iii., where the supernatural serpent is clearly acquainted with the properties of the tree of life.' Fergusson, p . 259 .

Perhaps the sloughing more than any other feature stimulated primitive See also:

speculation; cf . Winternitz, p . 28 . 2 See Crooke, ii . I and 33 sqq . ; C . G . Leland, See also:Etruscan See also:Roman Remains, p . 283; Winternitz 37 se q.; A . W . See also:Buckland, Anthropological Studies (1891), pp . 104-139 (on serpents in connexion with metallurgy and See also:precious stones) .

3 Excavators know how the popular mind associates their labours with See also:

search for hidden treasure, and no doubt the wealth of dead civilizations often stimulated the See also:imagination of subsequent generations . A gruesome Indian story (Crooke, ii . 136) shows how old treasure-See also:chambers could actually See also:harbour enormous and deadly See also:snakes .
