rails, locomotives, mining machinery, steam-boilers, stoves, carriages, edge-tools, &c. A public library, a theatre, an academy of music, a hospital, a public hall, a driving park, a Roman Catholic cathedral, a home for the friendless, and a museum of Indian stone relics are among the more prominent features of the place. The population was 9223 in 1860, 35,092 in 1870, and 45,850 in 1880. Slocum Farm, as the site was called subsequent to 1798, saw its first blast-furnace erected in 1840 by George and Selden Scranton, who soon added a rolling-mill and the manufacture of rails. The opening of the railway in 1856 gave a great stimulus to the new town (i954), which obtained a city charter in 1866. It is divided into twenty-one wards, of which the 4th, 5th, 6th, 14th, 15th, and 18th are known as Hyde Park, the 1st, 2d, and 3d as Providence. SCREAMER, a bird inhabiting Guiana and the Amazon valley, so called in 1781 by Pennant (Gen. Birds, p. 37) “from the violent noise it makes,”—the Palamedea cornuta of Linnaeus. First made known in 1648 by Marcgrave under the name of “Anhima,” it was more fully described and better figured by Buffon under that of Kamichi, still applied to it by French writers. Of about the size of a Turkey, it is remarkable for the curious “horn” or slender caruncle, more than three inches long, it bears on its crown, the two sharp spurs with which each wing is armed, and its elongated toes. Its plumage is plain in colour, being of an almost uniform greyish black above, the space round the eyes and a ring round the neck being variegated with white, and a patch of pale rufous appearing above the carpal joint, while the lower parts of the body are white. Closely related to this bird is another first described by Linnaeus as a species of Parra (JACANA, vol. xiii. p. 531), to which group it certainly does not belong, but separated therefrom by Illiger to form the genus Chauna, and now known as C. chavaria, very generally in English as the “Crested Screamer,” a name which was first bestowed on the SERIEMA (q.v.). This bird inhabits the lagoons and swamps of Paraguay and Southern Brazil, where it is called “Chajá” or “Chaka,” and is smaller than the preceding, wanting its “horn,” but having its head furnished with a dependent crest of feathers. Its face and throat are white, to which succeeds a blackish ring, and the rest of the lower parts are white, more or less clouded with cinereous. According to Mr Gibson (Ibis, 1880, pp. 165, 166), its nest is a light construction of dry rushes, having its foundation in the water, and contains as many as six eggs, which are white tinged with buff. The young are covered with down of a yellowish brown colour. A most singular habit possessed by this bird is that of rising in the air and soaring there in circles at 2n immense altitude, uttering at intervals the very loud cry of which its local name is an imitation. From a dozen to a score may be seen at once so occupying themselves. The young are often taken from the nest and reared by the people to attend upon and defend their poultry, a duty which is faithfully” and, owing to the spurs with which the Chaka's wings are armed, successfully discharged. Another very curious property of this bird, which was observed by Jacquin, who brought it to the notice of Linnaeus,” is its emphysematous condition,-there being a layer of air-cells between the skin and the muscles, so that on any part of the body being pressed a crackling sound is heard. In Central America occurs another species, C. derbiana, chiefly distinguished by the darker colour of its plumage. For this a distinct genus, Ischyrornis, was proposed, but apparently without necessity, by Reichenbach (Syst. Avium, p. xxi.). The taxonomic position of the Palamedeidae, for all will * Under this name its curious habits have been well described by Mr W. H. Hudson (Gentleman's Magazine, Sept. 1885, pp. 280-287). * Hence Latham's name for this species is “Faithful Jacana,”—he suppog it to belong to the genus in which Linnaeus placed it.

allow to the Screamers the rank of a Family at least, has been much debated, and cannot be regarded as fixed. Their Anserine relations were pointed out by Prof. Parker in the Zoological Proceedings for 1863 (pp. 511-518), and in the same work for 1867 Prof. Huxley placed the Family among his Chenomorphae; but this view was contravened in 1876 by Garrod, who said, “The Screamers must have sprung from the primary avian stock as an independent offshoot at much the same time as did most of the other important families.” Accordingly in 1880 Mr Sclater regarded them as forming a distinct “Order,” Palamedea, which he, however, placed next to the true Anseres, from the neighbourhood of which, as has been already stated (ORNITHOLOGY, vol. xviii. p. 47), the present writer thinks the Palamedeidae can hardly be removed. (A. N.) SCREW. The screw is the simplest instrument for

converting a uniform motion of rotation into a uniform

motion of translation (see MECHANICs, vol. xv. p. 754). Metal screws requiring no special accuracy are generally cut by taps and dies. A tap is a cylindrical piece of steel having a screw on its exterior with sharp cutting edges; by forcing this with a revolving motion into a hole of the proper size, a screw is cut on its interior forming what is known as a nut or female screw. The die is a nut with sharp cutting edges used to screw upon the outside of round pieces of metal and thus produce male screws. More accurate screws are cut in a lathe by causing the carriage carrying the tool to move uniformly forward, thus a continuous spiral line is cut on the uniformly revolving cylinder fixed between the lathe centres. The cutting tool may be an ordinary form of lathe tool or a revolving saw-like disk. (See MACHINE Tools, vol. xv. p. 153.)

Errors of Screws.-For scientific purposes the screw must be so regular that it moves forward in its nut exactly the same distance for each given angular rotation around its axis. As the mountings of a screw introduce many errors, the final and exact test of its accuracy can only be made when it is finished and set up for use. A large screw can, however, be roughly examined in the following manner. (1) 'See whether the surface of the threads has a perfect

polish. The more it departs from this, and approaches the rough

torn surface as cut by the lathe tool, the worse it is. A perfect screw has a perfect polish. (2) Mount upon it between the centres of a lathe and the slip a short nut which fits perfectly. If the nut moves from end to end with equal friction, the screw is uniform in diameter. If the nut is long, unequal resistance may be due to either an error of run or a bend in the screw. (3) Fix a microscope on the lathe carriage and focus its single cross-hair on the edge of the screw and parallel to its axis. If, the screw runs true at every oint, its axis is straight. (4) Observe whether the short nut runs rom end to end of the screw without a wabbling motion when the screw is turned and the nut kept from revolving. If it wabbles the screw is said to be drunk. One can see this error better b fixing a long pointer to the nut, or by attaching to it a mirror o: observing an image in it with a telescope. The following experiment will also detect this error. (5) Put upon the screw two wellfitting and rather short nuts, which are kept from revolving by arms bearing against a straight edge parallel to the axis of the screw. Let one nut carry an arm which supports a microscope focused on a line ruled on the other nut. Screw this combination to dislerent parts of the screw. If during one revolution the microscope remains in focus, the screw is not drunk; and, if the cross-hairs bisect the line in every position, there is no error of run. Making Accurate Screws.--To produce a screw of a foot or even a yard long with errors not exceeding rowth of an inch is not difficult. rofessor William A. Rogers of Harvard observatory has invented a process in which the tool of the lathe while cutting the screw is moved so as to counteract the errors of the lathe screw. The screw is then partly ground to get rid of local errors. But, where the highest accuracy is needed, we must resort in the case of screws, as in all other cases, to grinding. A long solid nut, tightly fitting the screw in one position, cannot be moved freely to another position unless the screw is very accurate. If grinding material is applied and the nut is constantly tightened, it will grind out all errors of run, drunkenness, crookedness, and lo of size. The condition is that the nut must be long, rigid, and capable of being tightened as the grinding proceeds; also the screw must be ground longer than it will finally be needed so that the imperfect ends may be removed. The following process will produce a screw suitable for ruling gratings for optical purposes. , Suppose it is our purpose to produce a screw which is finally to be 9 inches long, not including bearings, and 1% inches in diameter. Select, a bar of soft Bessemer steel, which has not the hard spots usually found in cast steel, about 1; inches in diameter and 30 long. Put it between lathe centres and turn it down to 1 inch diameter everywhere, except about 12 inches in the centre, where it is left a little over 1% inches in diameter for cutting the screw. Now cut the screw with a triangular thread a

little sharper than 60°. Above all, avoid a fine screw, using about.

20 threads to the inch. The grinding nut, about 11 incries 10ng, has now to be made. Fig. 1 represents a section of the nut, which is made of brass, or better d d c b c 5 to, o. \o

of Bessemer steel. . It consists of four segments, a, n, which can be drawn about the screw by two collars, b, b, and the screw c. Wedges between the segments prevent too great pressure on the screw, The final clamping is effected by the rings and screws, d, d, which enclose the flanges, e, of the segments. The screw is now Fo in a lathe and surrounded by water whose temperature can e kept constant to 1° C., and the nut placed on it. In order that the weight of the nut may not make the ends too small, it must either be counterbalanced by weights hung from a rope, passing over pulleys in the ceiling, or the screw must be vertical during the whole process. Emery and oil seem to be the only available grinding materials, though a softer silica powder might be used towards the end of the operation to clean off the emery and prevent future wear. . Now grind the screw in the nut, making the nut pass backwards and forwards over the screw, its whole range being nearly 20 inches at first. Turn the nut end for end every ten minutes and continue for two weeks, finally making the range of the nut only about 10 inches, using finer washed emery and moving the lathe slower to avoid heating. Finish with a fine silica wder or rouge. During the process, if the thread becomes too lunt, recut the nut by a short tap so as not to change the pitch at any point. . This must of course not be done less than five days before the finish. Now cut to the proper length ; centre again in the lathe under a microscope; and turn the bearings. . A screw so ound has less errors than from any other system of mounting. #. periodic error especially will be too small to be discovered, though the mountings and graduation and centering of the head will introduce it; it must therefore finally be corrected. Mounting of Screws.-The mounting must be devised most carefully, and is indeed more difficult to make without error than"the screw itself. The principle which should be adopted is that no workmanship is persect; the design must make up for its imperfections. Thus the screw can never be made to run true on its bearings, and hence the device of resting one end of the carriage on the nut must be rejected. Also all rigid connexion between the nut and the carriage must be avoided, as the screw can never be adjusted parallel to the ways on which the carriage rests. For many purposes, such as ruling optical gratings, the carriage must move accurately forward in a straight line as far as the horizontal plane is concerned, while a little curvature in the vertical plane produces very little effect. These conditions can be satisfied by making the ways W-shaped and grinding with a grinder somewhat shorter than the ways. By constant reversals and by lengthening or shortening the stroke, they will finally become nearly perfect. The vertical curvature can be sufficiently tested by a short carriage carrying a delicate spirit level. Another and very efficient form of ways is V-shaped with a flat top and nearly vertical sides. The carriage rests on the flat top and is held by springs against one of the nearly vertical sides. To determine with accuracy whether the ways are straight, fix a flat piece of glass on the carriage and rule a line on it by moving it under a diamond; reverse and rule another line near the first, and measure the distance apart at the centre and at the two ends by a micrometer. If the centre measurement is equal to the mean of the two end ones, the line is straight. This is better than the method with a mirror mounted on the carriage and a telescope. The screw itself must rest in bearings, and the end motion be prevented by a point beaving against its flat end, which is ...'. hardened steel or a flat diamond. Collar bearings introduce periodic crors. The secret of success is so to

the screw. Also, by causing it to move

design the nut and its connexions as to eliminate all adjustments of the screw and indeed all imperfect workmanship. The connexion

must also be such as to give means of correcting any residual

periodic errors or errors of run which may be introduced in the mountings or by the wear of the machine. The nut is shown in fig. 2... It is made in two halves, of wrought iron filled with boxwool or lignum vitae plugs, on which the screw is cut. To each half a long piece of sheef steel is fixed which bears against a guidin edge, to be described resently. . The two halves are held to the screw by springs, so that each moves forward almost independently of the other. To join the nut to the N carriage, a ring is attached to the latter, vertical and which can turn round a The bars fixed midway on the two halves against this ring at points 90° distant Hence each half does its share independother in moving the carriage forward. parallelism between the screw and the tricity in the screw mountings thus the forward motion of the carriage.

Fig. 2. duce it ghosts" in the spectrum.” Indeed this is the most sensitive method of detecting the existence of this error, and it is practically impossible to mount the most perfect of screws without introducing it. A very practical method of determining this error is to rule a short grating with very long lines on a piece of common thin plate glass; cut it in two with a diamond and superimpose the two halves with the rulings together and displaced sideways over each other one-half the pitch of the screw. On now looking at the plates in a proper light so as to have the spectral colours show through it, dark lines will appear, which are wavy if there is a periodic error and straight if there is none. By measuring the comparative amplitude of the waves and the distance apart of two lines, the amount of the periodic error can be determined. The phase of the periodic error is best found by a series of trials after setting the corrector at the o amplitude as determined above. A machine o made as above and kept at a constant temperature should be able to make a scale of 6 inches in length, with errors at no point exceeding roorowth of an inch. When, however, a grating of that length is attempted at the rate of 14,000 lines to the inch, four days and nights are required and the result is seldom perfect, possibly on account of the wear of the machine or changes of temperature. Gratings, however, less than 3 inches long are easy to make. (H. A. R.) SCRIBE, AUGUSTIN EUGENE (1791-1861), the most popular playwright of France, was born at Paris on 24th December 1791, and died there on 20th February 1861. His father was a silk merchant and he was well educated, being destined for the bar. But, having a real gift for the theatre (a gift which unfortunately was not allied with sufficient literary power to make his works last), he very soon broke away from professional study and at the age of twenty produced, in collaboration, as is common in France, the first of a series of dramas which continued for fifty years. Les Dervis (1811) is usually cited as the first play in which he took a hand, though, as for some time he did not sign his work, identification is somewhat difficult. He achieved no distinct success till 1816, when Une Nuit de Garde Nationate made him in a way famous. Thenceforward his fertility was unceasing and its results prodigious. There may be in existence a complete list of Scribe's works, but we have never seen any that pretended to be such. He wrote every kind of drama—vaudevilles, 1 In a machine made by the present writer for ruling gratings the periodic error is entirely due to the graduation and centering of the head. The uncorrected periodie error from this cause displaces the lines rotormth of an inch, which is sufficient to entirely ruin all gratings

comedies, tragedies, opera-libretti. To one theatre alone he is said to have furnished more than a hundred pieces. But his life was entirely uneventful, and his election to the Academy in 1834 is almost the only incident which deserves chronicling. It ought to be said to Scribe's credit that, although he was the least original of writers and was more an editor of dramas than a dramatist, although he was for many years an object of the bitterest envy to impecunious geniuses owing to his pecuniary success, and although he never has pleased and never can please any critic who applies purely literary tests, his character stands very high for literary probity and indeed generosity. He is said in some cases to have sent sums of money for “copyright in ideas” to men who not only had not actually collaborated with him but who were unaware that he had taken suggestions from their work. His industry was untiring and his knowledge both of the mechanism of the stage and of the tastes of the audience was wonderful. Nevertheless he hardly deserves a place in literature, his style being vulgar, his characters commonplace, even his plots lacking power and grasp. He wrote a few novels, but none of any mark. The best known of Scribe's pieces after his first successful one are Une Chaîne (1842), Le Verre d’Eau (1842), Adrienne Lecouvreur (1849), and the libretti of many of the most famous operas of the middle of the century, especially those of Auber and Meyerbeer. SCRIBES. See IsrAEL, vol. xiii. p. 419. SCRIVENER'S PALSY. See CRAMP, vol. vi. p. 543. SCROFULA or STRUMA (formerly known in England as “king's evil,” from the belief that the touch of the sovereign could effect a cure'), a constitutional morbid condition generally exhibiting itself in early life, and characterized mainly by defective nutrition of the tissues and by a tendency to inflammatory affections of a low type with degenerative changes in their products. The subject has been considered in most of its features under PATHoLogy (vol. xviii. p. 405), and only a further brief reference is here necessary. Scrofula may be either inherited or acquired. Heredity is of all causes the most potent, and naturally operates with greater certainty where both parents possess the taint. As in all hereditary diseases, however, the liability may be scarcely perceptible for one or two generations, but may then reappear. Other causes referable to parentage may readily produce this constitutional state in children, as weakness or ill health in one or both parents, and, as seems probable, marriages of consanguinity. But, apart altogether from hereditary or congenital influences, the scrofulous habit is frequently developed, especially in the young, by such unfavourable hygienic conditions as result from overcrowded, cold, and dark dwellings, insufficient and improper food, exposure, and debauchery. Even among the old in such circumstances the evidences of scrofula may be seen to present themselves where before they had been absent. There are two well-marked types of the scrofulous constitution to be often observed, especially among the young. In the one the chief features are a fair complexion with delicate thin skin, blue eyes, dilated pupils, long eyelashes, soft muscles, and activity of the circulatory and nervous system; while in the other the skin is dark, the features heavy, the figure stunted, and all the functions, physical and mental, inactive. In many instances, however, it will be found that both types are more or less mixed together in one individual. The manifestations of scrofula generally appear in early life, and are often exhibited in young

children during the first dentition by inflammatory skin eruptions of obstinate character on the face and other parts; later on in youth there appear glandular swellings either externally, as on the neck, or affecting the gland structures of the chest or abdomen, while at the same time mucous membranes and bones may become implicated. The distinctive features of the scrofulous inflammatory affections are their tendency to chronicity and to suppurative and degenerative changes, the affected parts either healing slowly with resulting disfigurement, as on the neck, or continuing to retain traces of the products of the diseased action, which may set up serious disturbance of the health at some future time. Further, the scrofulous constitution always influences the duration and progress of any disease from which the individual may suffer, as well as its results. Thus in pneumonia, to which the scrofulous would seem to be specially liable, the products of the inflammation are not readily absorbed as in previously healthy persons, but, remaining in the lung-tissues, are: apt to undergo caseous degenerative changes, which may issue in phthisis (see PNEUMONIA and PHTHISIs)... The cónnexion of scrofula with tubercle is pointed out in the article PATHOLOGY (loc. cit.). Scrofula may under favourable circumstances tend to improvement as age advances, and it occasionally happens that persons who in early life showed unmistakable evidences of this condition appear ultimately to outgrow it, and become in all respects healthy and vigorous. The treatment is essentially similar to - that described for rickets or phthisis, and is partly preventive and partly curative. It consists mainly in hygienic measures to promote the health and nutrition of the young, and of suitable diet, tonics, &c., where evidences of the disease have declared themselves. See RICKETs, PHTHISIs. SCRUB-BIRD, the name (for want of a better, since it is not very distinctive) conferred upon the members of an Australian genus, one of the most curious ornithological types of the many furnished by that country. The first examples were procured by the late Mr Gilbert between Perth and Augusta in West Australia, and were described by Gould in the Zoological Society's Proceedings for 1844 (pp. 1, 2) as forming a new genus and species under the name of Atrickia clamosa, the great peculiarity observed by that naturalist being the absence of any bristles around the gape, in which respect alone it seemed to differ from the already known genus Sphenura. In March 1866 Mr Wilcox obtained on the banks of the Richmond river on the eastern side of Australia some other examples, which proved the existence of a second species, described by Mr Ramsay in the Proceedings for that year (pp. 438-440) as A. rufescens; but still no suspicion of the great divergence of the genus from the ordinary Passerine type was raised, and it was generally regarded as belonging to the Maluridae or Australian Warblers. However, the peculiar formation of the sternum in Atrichia attracted the present writer's attention almost as soon as that of A. clamosa was exhibited in the museum of the College of Surgeons, and at his request Mr Ramsay a little later sent to the museum of the university of Cambridge examples in spirit of A. rufescens, which showed a common structure. One of the sternal peculiarities was noticed by Mr Sclater (Ibis, 1874, p. 191, note); and in the present work (BIRDs, iii. p. 741) the Scrub-birds were declared to form a distinct Family, Atrichiidae, standing, so far as was known, alone with the Lyre-birds (see vol. xv. p. 115) as “abnormal Passeres.” §. the same view was also taken the next year by Garrod, who, in the Proceedings for 1876 (pp. 516, 518, pl. lii. figs. 4-7), further dwelt on the taxonomic importance of the equally remarkable characters of the syringeal muscles exhibited alike bv.

(A. N.) SCUDERY is the name of a family which is said to Have been of Italian origin and to have transferred itself to Provence, but which is only known by the singular brother and sister who represented it during the 17th century. GEORGES DE SCUDERY (1601-1667), the elder of the pair, was born at Havre, whither his father had moved from Provence, in 1601. He served in the army for some time, and, though in the vein of gasconading which was almost peculiar to him he no doubt exaggerated his services, there seems little doubt that he was a stout soldier. But he conceived a fancy for literature before he was thirty, and during the whole of the middle of the century he was one of the most characteristic figures of Paris. Despite his own merit, which was not inconsiderable, and his sister's, which was more, he was unlucky in his suits for preferment. Indeed from some stories told by men not his friends he seems to have hurt his own chances by independence of spirit. He received, however, the governorship of the fortress of Notre Dame de la Garde near Marseilles in 1643, and in 1650 was elected to the Academy. Long before he had made

himself conspicuous by a letter attacking Corneille's Cid, which he addressed to that body. He was himself an industrious dramatist, L'Amour Tyrannique being the chief piece which (and that only partially) has escaped oblivion. His other most famous work was the epic of Alaric (1654). He lent his name to his sister's first romances, but did little beyond correcting the proofs. His death occurred at Paris on 14th May 1667. Scudéry's swashbuckler affectations (he terminates his introduction to the works of Théophile de Viaud by something like a challenge in form to any one who does not admit the supremacy of the deceased poet), the bombast of his style, and his various oddities have been rather exaggerated by literary gossip and tradition. Although probably not quite same, he had some poetical power, a fervent love of literature, a high sense of honour and of friendship. His sister MADELEINE (1607-1701), born also at Havre in 1607, was a writer of much more ability and of a much better regulated character. She was very plain and had no fortune, but her abilities were great and she was very well educated. Establishing herself at Paris with her brother, she was at once admitted to the Rambouillet coterie, afterwards established a salon of her own under the title

of the Société du Samedi, and for the last half of the 17th

century, under the pseudonym of “Sapho’’ or her own name, was acknowledged as the first blue-stocking of France and of the world. Her celebrated novels, Artamene ou le Grand Cyrus, Clélie, Ibrahim ou l'Illustre Bassa, Almahide,

and others are known by quotation to every one, and were

the delight of all Europe, including persons of the wit and sense of Madame de Sévigné. But for at least a century and a half they have lain unread, and their immense length has often been satirized even by persons well read in letters with the term “folio,” when in fact they were originally issued in batches of small octavos, sometimes (allowing for two parts to each volume) running to a score or so. Neither in conception nor in execution will they bear criticism as wholes. With classical or Oriental personages for nominal heroes and heroines, the whole language and action are taken from the fashionable ideas of the time, and the personages can be identified either really or colourably with Mademoiselle de Scudéry's contemporaries. The interminable length of the stories is made out by endless conversations and, as far as incidents go, chiefly by successive abductions of the heroines, cónceived and related in the most decorous spirit, for Mademoiselle de Scudéry is nothing if not decorous. Nevertheless, although the books can hardly now be read through, it is still possible to perceive their attraction for the wits, both male and female, of a time which certainly did not lack wit. In that early day of the novel prolixity did not repel. “Sapho.” had really studied mankind in her contemporaries and knew how to analyse and describe their characters with fidelity and point. She was a real mistress of conversation, a thing quite new to the age at least as far as literature was concerned, and proportionately welcome. She could moralize—a favourite employment of the time— with sense and propriety, and the purely literary merits of the style which clothed the whole were considerable. Madeleine survived her, brother more than thirty years (scandal says that she was not sorry to be relieved from his humours), and in her later days published numerous volumes of conversations (to a great extent extracted from her novels) and short moral writings. Dryden says that he had heard of an intention on her part to translate the Canterbury Tales, and it is not impossible. She never lost either her renown or her wits or her good sense, and died at Paris on 2d June 1701. It is unfortunate and rather surprising that no one has recently attempted an anthology from her immense work.

HE present article is confined to the sculpture of the
Middle Ages and modern times; classical sculpture

has been already treated of under ARCHEoLogy (CLAssICAL), vol. ii. p. 343 sq., and in the articles on the several individual artists.

In the 4th century A.D., under the rule of Constantine's successors, the plastic arts in the Roman world reached the lowest point of degradation to which they ever fell. Coarse in workmanship, intensely feeble in design, and utterly without expression or life, the pagan sculpture of that time is merely a dull and ignorant imitation of the work of previous centuries. The old faith was dead, and the art which had sprung A TITLoo -ofrom it died with it. In the same century a large amount of sculpture was produced by Christian workmen, which, though it reached no very high standard of merit, was at least far superior to the pagan work. Although it shows no, increase of technical skill or knowledge of the human form, yet the mere fact that it was inspired and its subjects supplied by a real living faith was quite sufficient to give it a vigour and a dramatic force which raise it aesthetically far above the expiring efforts of paganism. Fig. 1 shows a very fine Christian relief of ill|| the 4th century, with a noble figure of an archangel holding an orb and a sceptre. It is a leaf from M an ivory consular dip- | tych, inscribed at the top \| AEXOY IIAPONTA RAI Mo MA60N THN AITIAN, A “Receive these presents \| ---wo and having learnt the oc- \|| o o | casion . . .” A number of large marble sarcophagi are the chief existing specimens of this early Christian sculpture. In general design they are close copies of pagan tombs, and are richly decorated outside with reliefs. The subjects of these are usually scenes from the Old and New Testaments. From the former those subjects were selected which were supposed to have some typical reference to the life of Christ : the Meeting of Abraham and Melchisedec, the Sacrifice of Isaac, Daniel among the Lions, Jonah and the Whale, are those which most frequently occur. Among the New Testament scenes no representations occur of Christ's sufferings;" the subjects chosen illustrate His power and beneficence: the Sermon on the Mount, the Triumphal Entry, into Jerusalem, and many of His miracles are

One of the finest in the former collection was taken from the crypt of the old basilica of St Peter; it contained the body of a certain Junius Bassus, and dates from the year 359.” Many other similar sarcophagi were made in the provinces of Rome, especially Gaul; and fine specimens exist in the museums of Arles, Marseilles, and Aix; those found in Britain are of very inferior workmanship. In the 5th century other plastic works similar in style were still produced in Italy, especially. reliefs in ivory (to a certain extent imitations of the later consular diptychs), which were used to decorate episcopal thrones or the bindings of MSS. of the Gospels.
