JOSEPH See also:BARBER See also:LIGHTFOOT (1828-1889)  , See also:English theologian and See also:bishop of See also:Durham, was See also:born at See also:Liverpool on the 13th of See also:April 1828 . His See also:father was a Liverpool accountant . He was educated at See also:King See also:Edward's school, See also:Birmingham, under See also:James See also:Prince See also:Lee, afterwards bishop of See also:Manchester, and had as contemporaries B . F . See also:Westcott and E . W . See also:Benson . In 1847 See also:Lightfoot went up to Trinity See also:College, See also:Cambridge, and there read for his degree with Westcott . He graduated See also:senior classic and 3oth wrangler, and was elected a See also:fellow of his college . From 1854 to 1859 he edited the See also:Journal of Classical and Sacred See also:Philology . In 1857 he became See also:tutor and his fame as a See also:scholar See also:grew rapidly . He was made Hulsean See also:professor in 1861, and shortly afterwards See also:chaplain to the Prince See also:Consort and honorary chaplain in See also:ordinary to the See also:queen .

In 1866 he was See also:

Whitehall preacher, and in 1871 he became See also:canon of St See also:Paul's . His sermons were not remarkable for eloquence, but a certain solidity and See also:balance of See also:judgment, an See also:absence of partisanship, a sobriety of expression combined with clearness and force of diction, attracted hearers and inspired them with confidence . As was written of him in The Times after his See also:death, " his See also:personal See also:character carried immense See also:weight, but his See also:great position depended still more on the universally recognized fact that his belief in See also:Christian truth and his See also:defence of it were supported by learning as solid and comprehensive as could be found anywhere in See also:Europe, and by a See also:temper not only of the utmost candour but of the highest scientific capacity . The days in which his university See also:influence was asserted were a See also:time of much shaking of old beliefs . The disintegrating speculations of an influential school of See also:criticism in See also:Germany were making their way among English men of culture just about the time, as is usually the See also:case, when the See also:tide was turning against them in their own See also:country . The See also:peculiar service which was rendered at this juncture by the ` Cambridge School' was that, instead of opposing a See also:mere dogmatic opposition to the See also:Tubingen critics, they met them frankly on their own ground; and instead of arguing that their conclusions ought not to be and could not be true, they simply proved that their facts and their premisses were wrong . It was a characteristic of equal importance that Dr Lightfoot, like Dr Westcott, never discussed these subjects in the mere spirit of controversy . It was always patent that what he was chiefly concerned with was the substance and the See also:life of Christian truth, and that his whole energies were employed in this inquiry because his whole See also:heart was engaged in the truths and facts which were at stake . He was not diverted by controversy to See also:side-issues; and his labour was devoted to the See also:positive elucidation of the sacred documents in which the Christian truth is enshrined." In 1872 the See also:anonymous publication of Supernatural See also:Religion created considerable sensation . In a See also:series of masterly papers in the Contemporary See also:Review, between See also:December 1874 and May 1877, Lightfoot successfully undertook the defence of the New Testament canon . The articles were published in collected See also:form in 1889 . About the same time he was engaged in contributions to W .

See also:

Smith's See also:Dictionary of Christian See also:Biography and Dictionary of the See also:Bible, and he also joined the See also:committee for revising the See also:translation of the New Testament . In 1875 he became See also:Lady See also:Margaret professor of divinity in See also:succession to See also:William See also:Selwyn . He had previously written his commentaries on the epistles to the See also:Galatians (1865), See also:Philippians (1868) and See also:Colossians (1875), the notes to which were distinguished by See also:sound judgment and enriched from his large See also:store of patristic and classical learning . These commentaries may be described as to a certain extent a new departure in New Testament exegesis . Before Lightfoot's time commentaries, especially on the epistles, had not infrequently consisted either of See also:short homilies on particular portions of the See also:text, or of endeavours to enforce foregone conclusions, or of attempts to decide with See also:infinite See also:industry and ingenuity between the interpretations of former commentators . Lightfoot, on the contrary, endeavoured to make his author interpret himself, and by considering the See also:general See also:drift of his See also:argument to discover his meaning where it appeared doubtful . Thus he was able often to recover the meaning of a passage which had See also:long been buried under a heap of contradictory glosses, and he founded a school in which sobriety and See also:common sense were added to the industry and ingenuity of former commentators . In 1879 Lightfoot was consecrated bishop of Durham in succession to C . See also:Baring . His moderation, See also:good sense, See also:wisdom, temper, firmness and erudition made him as successful in this position as he had been when professor of See also:theology, and he speedily surrounded himself with a See also:band of scholarly See also:young men . He endeavoured to combine his habits of theological study with the See also:practical See also:work of See also:administration . He exercised a large liberality and did much to further the work of See also:temperance and purity organizations .

He continued to work at his See also:

editions of the Apostolic Fathers, and in 1885 published an edition of the Epistles of See also:Ignatius and See also:Polycarp,627 See also:collecting also a large store of valuable materials for a second edition of See also:Clement of See also:Rome, which was published after his death (1st ed., 1869) . His defence of the authenticity of the Epistles of Ignatius is one of the most important contributions to that very difficult controversy . His unremitting labours impaired his See also:health and shortened his splendid career at Durham . He was never married . He died at See also:Bournemouth on the 21st of December 1889, and was succeeded in the episcopate by Westcott, his schoolfellow and lifelong friend . Four volumes of his Sermons were published in 189o . LIGHTHOUSE, a form of See also:building erected to carry a See also:light for the purpose of warning or guidance, especially at See also:sea . I . See also:EARLY See also:HISTORY.—The earliest lighthouses, of which records exist, were the towers built by the Libyans and Cushites in See also:Lower See also:Egypt, See also:beacon fires being maintained in some of them by the priests . See also:Lesches, a See also:Greek poet (c.66o B.C.) mentions a lighthouse at Sigeum (now Cape Incihisari) in the See also:Troad . This appears to have been the first light regularly maintained for the guidance of mariners . The famous Pharos 1 of See also:Alexandria, built by Sostratus of See also:Cnidus in the reign of See also:Ptolemy II .

(283–247 B.C.) was regarded as one of the wonders of the See also:

world . The See also:tower, which took its name from that of the small See also:island on which it was built, is said to have been 600 ft. in height, but the See also:evidence in support of this statement is doubtful . It was destroyed by an See also:earthquake in the 13th See also:century, but remains are said to have been visible as See also:late as 1350 . The name Pharos became the general See also:term for all lighthouses, and the term " pharology " has been used for the See also:science of lighthouse construction . The tower at See also:Ostia was built by the See also:emperor See also:Claudius (A.D . 50) . Other famous See also:Roman lighthouses were those at See also:Ravenna, See also:Pozzuoli and See also:Messina . The See also:ancient Pharos at See also:Dover and that at See also:Boulogne, later known as la Tour d'Ordre, were built by the See also:Romans and were probably the earliest lighthouses erected in western Europe . Both are now demolished . The light of Cordouan, on a See also:rock in the sea at the mouth of the See also:Gironde, is the earliest example now existing of a See also:wave-swept tower . Earlier towers on the same rock are attributed the first to See also:Louis le Debonnaire (c . A.D .

805) and the second to Edward the See also:

Black Prince . The existing structure was begun in 1584 during the reign of See also:Henri II. of See also:France and completed in 1611 . The upper See also:part of the beautiful See also:Renaissance building was removed towards the end of the 18th century and replaced by a loftier cylindrical structure rising to a height of 207 ft. above the rock and with the See also:focal See also:plane of the light 196 ft. above high See also:water (fig . I) . Until the 18th century the light exhibited from the tower was from an See also:oak See also:log See also:fire, and subsequently a See also:coal fire was in use for many years . The ancient tower at See also:Corunna, known as the See also:Pillar of See also:Hercules, is supposed to have been a Roman Pharos . The Torre del See also:Capo at See also:Genoa originally stood on the promontory of See also:San Berrique . It was built in 1139 and first used as a lighthouse in 1326 . It was rebuilt on its See also:present site in 1643 . This beautiful tower rises 236 ft. above the cliff, the light being elevated 384 ft. above sea-level . A See also:lens light was first installed in 1841 . The Pharos of See also:Meloria was constructed by the Pisans in 1154 and was several times rebuilt until finally destroyed in 1290 .

On the See also:

abandonment of Meloria by the Pisans, they erected the still existing tower at See also:Leghorn in 1304 . In the 17th and 18th centuries numerous towers, on which were erected braziers or grates containing See also:wood or coal fires, were established in various positions on the coasts of Europe . Among such stations in the See also:United See also:Kingdom were See also:Tynemouth (c . 16o8), the Isle of May (1636),.St See also:Agnes (168o), St Bees (1718) and the See also:Lizard (1751) . The See also:oldest lighthouse in the United States is believed to be the See also:Boston light situated on Little See also:Brewster Island on the See also:south side of the See also:main entrance to Boston See also:Harbour, See also:Mass . It was established in 1716, the present structure dating from 1859 . During the See also:American See also:War of See also:Independence the lighthouse suffered many vicissitudes and was successively destroyed and rebuilt three times by the American or See also:British A full See also:account is given in See also:Hermann See also:Thiersch, Pharos Antike, See also:Islam and Occident (1909) . See also See also:MINARET . forces . At the third rebuilding in 1783 a See also:stone tower 68 ft. in height was erected, the illuminant consisting of four oil lamps . Other early lighthouse structures on the New See also:England See also:coast were those at See also:Beaver Tail, near the entrance to See also:Newport Harbour (1740), and the See also:Brant at the entrance to See also:Nantucket Harbour (1754) . A See also:watch-See also:house and beacon appear to have been erected on Beacon or Lighthouse Island as well as on Point Allerton See also:Hill near Boston, See also:prior to 1673, but these structures would seem to have been in the nature of look-out stations in time of war rather than lighthouses for the guidance of mariners .

2 . LIGHTHOUSE STRUCTURES.—The structures of lighthouses may be divided into two classes, (a) those on rocks, shoals or in other situations exposed to the force of the sea, and (b) the more numerous class of See also:

land structures . Wave-swept Towers.—In determining the See also:design of a lighthouse tower to be erected in a wave-swept position See also:consideration must be given to the See also:physical features of the site and its surroundings . Towers of this description are classified as follows: (i) See also:Masonry and See also:concrete structures; (2) Openwork See also:steel and See also:iron-framed erections on See also:pile or other See also:foundations; (3) See also:Cast iron plated towers; (4) Structures erected on See also:cylinder foundations . (I) Masonry Towers.—Masonry or concrete towers are generally preferred for erection on wave-swept rocks affording good See also:foundation, and have also been constructed in other situations where adequate foundations have been made by sinking caissons into a soft sea See also:bed . See also:Smeaton's tower on the Eddystone Rock is the See also:model upon which most later designs of masonry towers have been based, although many improvements in detail have since been made . In situations of great exposure the following requirements in design should be observed: (a) The centre of gravity of the tower structure should be as See also:low as possible . (b) The mass of the structure superimposed at any See also:horizontal See also:section must be sufficient to prevent its displacement by the combined forces of See also:wind and waves without dependence on the See also:adhesion at horizontal See also:joint faces or on the dovetailing of stones introduced as an additional safeguard . (c) The structure should be circular in See also:plan throughout, this form affording the least resistance to wave stroke and wind pressure in any direction.(d) The lower portion of the tower exposed to the See also:direct horizontal stroke of the waves should, for preference, be constructed with See also:vertical See also:face . The upper portion to be either straight with See also:uniform See also:batter or continuously curved in the vertical plane . See also:External projections from the face of the tower, except in the case of a See also:gallery under the See also:lantern, should be avoided, the See also:surface throughout being smooth . (e) The height from sea-level to the See also:top of the tower should be sufficient to avoid the obscuration of the light by broken water or dense spray See also:driving over the lantern .

(f) The foundation of the tower should be carried well into the solid rock . (g) The materials of which the tower is built should be of high See also:

density and of resistant nature . (h) The stones used in the construction of the tower, at any See also:rate those on the See also:outer face, should be dovetailed or joggled one to the other in See also:order to prevent their being dislodged by the sea during the See also:process of construction and as an additional safe-guard of stability . Of late years, See also:cement concrete has been used to a considerable extent for maritime structures, including lighthouses, either alone or faced with masonry . (2) Openwork Structures.—Many examples of openwork steel and iron lighthouses exist . Some typical examples are described hereafter . This form of design is suitable for situations where the tower has to be carried on a foundation of iron or steel piles driven or screwed into an insecure or sandy bottom, such as on shoals, See also:coral reefs and See also:sand See also:banks or in places where other materials of construction are exceptionally costly and where facility of erection is a desideratum . (3) Cast iron Towers.—Cast iron plated towers have been erected in many situations where the cost of stone or scarcity of labour would have made the erection of a masonry tower excessively expensive . (4) See also:Caisson Foundations.—Cylinder or caisson foundations have been used for lighthouse towers in numerous cases where such structures have been erected on sand banks or shoals . A remarkable instance is the Rothersand Tower . Two attempts have been made to sink a caisson in the outer See also:Diamond Shoal off Cape Hatteras on the See also:Atlantic coast of the United States, but these have proved futile . The following are brief descriptions of the more important wave-swept towers in various parts of the world .

Eddystone (Winstanley's Tower).—The Eddystone rocks, which See also:

lie about 14 M. off See also:Plymouth, are fully exposed to south-See also:west seas . The See also:reef is submerged at high water of See also:spring tides . Four towers have been constructed on the reef . The first lighthouse (fig . 2 was polygonal in plan and highly ornamented with galleries and projections which offered considerable resistance to the sea stroke . The work was begun by See also:Henry Winstanley, a See also:gentleman of See also:Essex, in 1695 . In 1698 it was finished to a height of 8o ft. to the wind See also:vane and the light exhibited, but in the following See also:year, in See also:con-sequence of damage by storms, the tower was increased in See also:diameter from 16 ft. to 24 ft. by the addition of an outer See also:ring of masonry and made solid to a height of 20 ft. above the rock, the tower being raised to nearly 120 ft . The work was completed in the year 1700 . The lower part of the structure appears to have been of stone, the upper part and lantern of See also:timber . During the great See also:storm of the loth of See also:November 1703 the tower was swept away, those in it at the time, including the builder, being drowned . Eddystone (Rudyerd's Tower, fig . 3).—This structure was begun in 1706 and completed in 1709 .

It was a See also:

frustum of a See also:cone 22 ft . 8 in. in diameter at the See also:base and 14 ft . 3 in. at the top . The tower was 92 ft. in height to the top of the lantern . The work consisted principally of oak timbers securely bolted and cramped together, the lower part being filled in solid with stone to add weight to the structure . The simplicity of the design and the absence of projections from the outer face rendered the tower very suitable to withstand the onslaught of the waves . The lighthouse was destroyed by fire in 1755 . Eddystone (Smeaton's Tower, fig . 4).—This famous work, which consisted entirely of stone, was begun in 1756, the light being first exhibited in 1759 . See also:John Smeaton was the first engineer to use dovetailed See also:joints for the stones in a lighthouse structure . 'The stones, which averaged i ton in weight, were fastened to each other by means of dovetailed vertical joint faces, oak See also:key wedges, and by oak See also:tree-nails wedged top and bottom, extending vertically from every course into the stones beneath it . During the 19th century the tower was strengthened on two occasions by the addition of heavy wrought iron ties, and the overhanging See also:cornice was reduced in diameter to prevent the waves from lifting the stones from their beds .

In 1877, owing partly to the undermining of the rock on which the tower was built and the insufficient height of the structure, the See also:

Corporation of Trinity House determined on the erection of a explosive See also:gun-See also:cotton See also:fog See also:signal has been erected, the bells being removed . At a lower level in the tower are installed 2 2I-in. parabolic silvered reflectors with 2-See also:wick burners, throwing a fixed light of 8000 See also:candle-See also:power over a danger known as the See also:Hand Deeps . The work of pre- paring the foundation was begun on the 17th of See also:July 1878, the foundation stone Foe°1 p,a,o being laid by the late See also:duke of See also:Edinburgh A -on the 19th of See also:August 1879 . The last stone was laid on the 1st of See also:June 1881, i and the light was exhibited for the first time on the 18th of May 1882 . The upper portion of Smeaton's tower, which was removed on completion of the new light-house, was re-erected on Plymouth See also:Hoe, where it replaced the old Trinity House sea See also:mark . One of the See also:principal features in the design of the new Eddystone lighthouse tower is the solid vertical base . This construction was much criticized at the time, but experience has proved that heavy seas striking the massive cylindrical structure are immediately broken up and See also:rush See also:round to the opposite side, spray alone ascending to the height of the lantern gallery . On the other hand, the waves striking the old tower at its foundation ran up the surface, which presented a curved face to the waves, and, unimpeded by any See also:projection until arriving at the lantern gallery, were partially broken up by the cornice and w. then spent themselves in heavy spray _- over the lantern . The See also:shock to which the cornice of the gallery was exposed was so great that stones were sometimes lifted from their beds . The new Eddy- stone tower presents another point of dissimilarity from Smeaton's structure, that the stones forming the floors consist of single corbels built into the See also:wall and constituting solid portions thereof . In Smeaton's tower the floors consisted of stone See also:arches, the thrust being taken by the walls of the tower itself, which were strengthened for the lRudyerd ,706 Smeaton 2756 'o I o ',o ao 3o w so 6o 70 8o sp ,4o Feet in new lighthouse in See also:place of Smeaton's tower Eddystone, New Lighthouse (J .

Douglass).—The site selected for the new tower is 120 ft . S.S.E. from Smeaton's lighthouse, where a suitable foundation was found, although a considerable section of the lower courses had to be laid below the level of low water . The vertical base is 44 ft. in diameter and 22 ft. in height . The tower (See also:figs . 5 and 6) is a See also:concave elliptic frustum, and is solid, with the exception of a fresh-water tank, to a height of 25 ft . 6 in. above high-water level . The walls above this level vary in thickness from 8 ft . 6 in. to 2 ft . 3 in. under the gallery, All the stones are Lighthouses on the Eddystone . dovetailed, both horizontally and vertically, on all joint faces, the stones of the foundation course being secured to the rock by Muntz See also:metal bolts . The tower contains 62,133 cub. ft. of See also:granite, weighing 4668 tons . The height of the structure from low water ordinary spring tides to the mean focal plane is 149 ft. and it stands 133 ft. above high water .

The lantern is a cylindrical helically framed structure with domed roof . The astragals are of gunmetal and the See also:

pedestal of cast iron . The
