Speaking generally, the sculptors of Assurbanipal were the pupils of those of Sennacherib, with, perhaps, a larger endowment of taste and skill. Under them Assyrian art aimed higher than ever before. It was fascinated by movement, and endeavoured to render its accidents and unforeseen turns. From this point of view we must draw particular attention to the pictures representing the campaign of Assurbanipal against the Elamites. In these the figures are more numerous and more closely packed than anywhere else, and the chisel has attacked episodes more complicated and more difficult to treat. Here, for instance, is a chariot upset upon the battle-field; it is turned completely over, while the struggling horses pull different ways, and the occupants are thrown out head foremost. There are many technical defects and mistakes of drawing, but the attempt is none the less interesting.
Some of the reliefs show the same confused accumulation of figures as in the time of Sennacherib. Now and then we find as many as six horizontal divisions, each from ten to fourteen inches high. But their height obeys no regular or constant rule. The central division, with the king in his chariot, is two feet high. No attempt is made to distinguish planes by varying the size of the figures, to mark the successive moments of the action by dividing the groups, or to give prominence to the main incidents; the confusion is unbroken. Here, as in all the battle pieces, a very singular convention may be noticed. There are no dead or beaten Assyrians. If we may believe the artist, the kings of Nineveh won all their battles without losing a man!
The hunting scenes are arranged with more judgment. In certain respects we might place them in the same class as the great reliefs from Nimroud. By right of their dignity and breadth, the latter must be considered the masterpieces of Assyrian sculpture, but these later works can boast an amount of energy and vitality and a truthfulness of handling that are worthy of no stinted praise. The master by whom the conception was thought out abandoned the overloaded backgrounds that his immediate predecessors had brought into vogue. He concentrated his attention on the figures, to which he gave all the value he could. They stand out with singular force against a field whose unbroken surfaces happily suggest the immensity of the naked plains on which the hunts took place. We have already shown how well the distinctive features and movements of the dog, the lion, and the wild ass are rendered; in our Fig. 126 we give another example of the same kind. A sentiment of real interest is stirred in us on behalf of these wild goats with their young, who run and feed on the steppe while horsemen and beaters prepare to drive them into the treacherous nets.

Elsewhere, on the other hand, the sculptor has furnished the beds of his reliefs with certain vegetable and floral forms chiselled with the greatest care. We may give, as an example, the kind of royal park or garden in which we saw a pair of tame lions (see above, Fig. 77). Behind the animals, to the right, there is a tree round which a vine clings and mounts. It is heavy with clusters of ripe fruit, and even the curling tendrils with which its branches end are not forgotten. On the left there is a palm tree, or, at least, its trunk. Between the vine and the palm tall flowering stems rear their heads. The artist has wished us to understand that fruits, sweet-smelling flowers, and umbrageous leafage, combined to make these gardens the most agreeable of retreats for a king fatigued with war against human enemies or the beasts of the desert. The same intention is traceable on the famous slab already figured (Vol. I. Figs. 27 and 28), which shows the king and queen at table in one of these royal gardens. We reproduce the chief group on a larger scale in order that the beauty of the execution may have a chance of making itself felt (Fig. 127). Notice the treatment of the vine that bends over the heads of the royal couple. The heads themselves have suffered, but all the rest of the plaque is in excellent condition. Notice the pattern on the royal robes, and the details of the furniture. The latter may be recognized as truthful renderings of the magnificent chairs and tables of bronze, inlaid with ivory and lapis-lazuli, of which so many fragments have been found in the Assyrian palaces. Every detail that the chisel could render has been faithfully copied. Except in colour and material, the objects themselves are before us. The fringed coverlet thrown over the king’s knees, the cushion on which he leans, the garland thrown over the arm of his couch, the system of metal uprights and cross pieces of which the queen’s throne, the king’s bed, and the small table placed between them consist, might all be restored without difficulty. The chiselled feet of all these objects resemble fir-cones in shape. In the case of the table they are connected with its body by lion’s paws. On the lower bar of the queen’s chair there is a small couchant lion.
Fig. 128.—Terra-cotta statuette. Actual size. British Museum. Drawn by Saint-Elme Gautier.
It may be thought, perhaps with truth, that the sculptor has overdone these details, and that his figures are, in some degree, sacrificed to the decorations about them. Other examples from the same series, give a higher idea of the sculpture of this time; we may cite especially a fragment possessed by the Louvre, in which the treatment is of the skilfullest (Plate X). It represents Assurbanipal in his war-chariot at the head of his army. The chariot itself, and all the accessories, such as the umbrella and the robes of the king and his attendants, are treated with great care but they do not unduly attract the eye of the spectator. We can enjoy, as a whole, the group formed by the figures in the chariot, and those who march beside and behind it. Its arrangement is clear and well balanced; there is no crowding, the spacing of the figures is well judged and the movement natural and suggestive. The king dominates the composition as he should, and his umbrella happily gathers the lines of the whole into a pyramid. In all this there is both knowledge and taste.
The best of the Assyrian terra-cottas also belong to this period. The merit of their execution may be gathered from the annexed statuette, which comes from the palace of Assurbanipal (Fig. 128). From the staff in its hands it has been supposed to represent a king, but we know that every Assyrian was in the habit of carrying a stick with a more or less richly ornamented head, and here we find neither a tiara nor the kind of necklace which the sovereign generally wore (see Fig. 116). I am inclined to think it is the image of a priest.
In conclusion we may say that, in some respects, Assyrian sculpture was in a state of progression when the fall of Nineveh came to arrest its development and to destroy the hopes it inspired.
§ 7.—Polychromy.
We have now studied Mesopotamian sculpture in its favourite themes, in its principal conventions, and in the fluctuations of its taste and methods of work; we have yet to ask whether this sculpture, which differed in so many ways from the plastic art of Egypt, differed from it also in absence of colour. We have put off this question until now, because we had first to determine what materials the architect and sculptor employed, how they employed them, and what part was played by figures in relief and in the round in the architectonic creations of Chaldæa and Assyria.
In speaking of Egypt we have explained how a brilliant light destroys the apparent modelling of objects, how, by the reflections it casts into the shadows, it interferes with our power to distinguish one distant plane from another.[273] In every country where a vertical sun shines in an unclouded sky, the decorator has had to invoke the help of colour against the violence of the light, has had to accept its aid in strengthening his contours, and in making his figures and ornaments stand out against their ground. In describing Egyptian polychromy we said that we should find the same tendency among other nations, different in character and origin, but subjected to the influence of similar surroundings. We also allowed it to be seen that we should have to notice many changes of fashion in this employment of colour. Colour played a different and more important part in one place or period than in another, and it is not always easy to specify the causes of the difference. In the Egyptian monuments hardly a square inch of surface can be found over which the painter has not drawn his brush; elsewhere, in Greece for instance, we shall find him more discreet, and his artificial tints restricted to certain well-defined parts of a figure or building.
Did Assyria follow the teaching of Egypt, or did she strike out a line of her own, and set an example of the reserve that was afterwards to find favour in Greece? That is the question to be answered. Before we can do so we must produce and compare the evidence brought forward by Botta, Layard, Place and others, who saw the Assyrian sculptures reappear in the light of day. Ever since those sculptures were recovered they have been exposed to the air; they have undergone all the handling and rubbing involved in a voyage to Europe; and for the last twenty or thirty years they have been subjected to the dampness of our climate. We need, then, feel no surprise that traces of colour still visible when the pick-axe of the explorer freed the alabaster slabs from their envelope of earth have now disappeared.
Before examining our chief witnesses, the men who dug up Khorsabad, and Nimroud, and Kouyundjik, we may, to some extent, foretell their answers. We have already explained how the Mesopotamian architect made use of colour to mask the poverty of his construction and to furnish the great bare walls of his clay buildings. Both inside and outside, the Assyrian palaces had the upper parts of their walls and the archivolts of their doors decorated with enamelled bricks or paintings in distemper. Is it to be supposed that where the reliefs began all artificial tinting left off, and that the eye had nothing but the dull grey of gypsum and limestone to wander to from the rich dyes of the carpets with which the floors were strewn? Nothing could well be more disagreeable than such a contrast. In our own day, and over the whole of the vast continent that stretches from China to Asia Minor, there is not a stuff, however humble, that is woven on the loom or embroidered by the needle, but betrays an instinctive feeling for harmony so true and subtle that every artist wonders at it, and the most tasteful of our art workmen despair of reaching its perfection, and yet many of these faultless harmonies were conceived and realized in the tent of the nomad shepherd. We can hardly believe that in the palace where official art lavished all its resources in honour of its master, there could be any part from which the gaiety that colour gives was entirely excluded, especially if it was exactly the part to which the eye of every visitor would be most surely attracted.
Before going into the question of evidence one might, therefore, make up our minds that the Assyrian architect never allowed any such element of failure to be introduced into his work; and the excavations have made that conclusion certain. The Assyrian reliefs were coloured, but they were not coloured all over like those of Egypt; the grain of the stone did not disappear, from one end of the frieze to the other, under a layer of painted stucco. Flandin, the draughtsman attached to the expedition of M. Botta, alone speaks of a coat of ochre spread over the bed of the relief and over the nude portions of the figures;[274] he confesses, however, that the traces were very slight and that they occurred only on a slab here and there. Botta, who saw the same slabs, thought his colleague mistaken.[275] Place is no less decided: “None of us,” he says, “could find any traces of paint upon the undraped portions of the figures, and it would be very extraordinary if among so many bare arms and bare legs, to say nothing of faces, not one should have retained any vestige of colour if they had all once been painted.”[276] We might be inclined to ask whether the traces of pigment that have been noticed here and there upon the alabaster might not have been the remains of a more widespread coloration, the rest of which had disappeared. Strong in his experience, Place thus answers any doubts that might be expressed on this point: “We never found an ornament, a weapon, a shoe or sandal, partially coloured; they were either coloured all over or left bare, while objects in close proximity were without any hue but their own. Sometimes eyes and eyebrows were painted, while hair and beard were left untouched; sometimes the tiara with which a figure was crowned or the fan it carried in its hand was painted while the hand itself and the hair that curled about the head showed not the slightest trace of such an operation; elsewhere colour was only to be found on a baldrick, on sandals, or the fringes of a robe.” Wherever these colours existed at all they were so fresh and brilliant at the time of discovery that no one thought of explaining their absence from certain parts of the work by the destruction of the pigment. “How is it,” continues Place, “that, if robes were painted all over, we only found colour on certain accessories, on fringes and embroideries? How is it that if the winged bulls were coated in paint from head to foot, not one of the deep grooves in their curled beards and hair has preserved the slightest vestige of colour, while the white and black of their eyes, which are salient rather than hollowed, remain intact? Finally, we may mention the following purely accidental, and therefore all the more significant, fact: a smudge of black paint, some two feet long, was still clearly visible on the breast of one of the colossi in the doorway of room 19.[277] How can we account for the persistence of this smudge, which must have fallen upon the monster’s breast while they were painting its hair, if we are to suppose that the whole of its body was covered with a tint which has disappeared and left no sign?”
Such evidence is decisive. The colouring of the Assyrian reliefs must always have been partial. The sculptor employed the painter merely to give a few strokes of the brush which, by the frankness and vivacity of their accent, should bring the frieze into harmony with the wall that enframed it. Nothing more was required to destroy the dull monotony of the long band of stone. At the same time these touches of colour helped to draw attention to certain details upon which the sculptor wished to insist.
For all this, four colours were enough. Observers agree in saying that black, white, red and blue made up the whole palette.[278] These tints were everywhere employed pretty much in the same fashion.[279]
In those figures in which drapery covered all but the head, the latter was, of course, more important than ever. The artist therefore set himself to work to increase its effect as much as he could. He painted the eyeball white, the pupil and iris, the eyebrows, the hair and the beard, black; sometimes the edges of the eyelids were defined with the same colour. The band about the head of the king or vizier is often coloured red, as well as the rosettes which in other figures sometimes decorate the royal tiara. The same tint is used upon fringes, baldricks, sandals, earrings, parasols and fly-flappers, sceptres, the harness of horses and the ornamental studs or bosses with which it was covered, and the points of weapons.[280] In some instances blue is substituted for red in these details. Place speaks of a fragment lost in the Tigris on which the colours were more brilliant than usual; upon it the king held a fan of peacock’s feathers coloured with the brightest mineral blue.[281]
When figures held a flower in their hands it was blue, and at Khorsabad a bird on the wing was covered with the same tint.[282] In some bas-reliefs red and blue alternate in the sandals of the figures and harness of the horses.[283] We find a red bow with a blue quiver.[284] The flames of towns taken and set on fire by the Assyrians were coloured red in many of the Khorsabad reliefs.[285]
A few traces of colour may still be discovered upon some of Sargon’s sculptures in the Louvre and upon those of Assurnazirpal in the British Museum.[286] I could find no remains of colour either upon the reliefs of Assurbanipal or upon those of Sennacherib, where, moreover, Layard tells us he could discover none.[287]
It would be very strange however, if in these palaces of the last of the Sargonids the decorator had deliberately renounced the beauties of that discreet system of polychromy of which the traces are to be found in all the earlier palaces. It is possible that these touches of colour were reserved for the last when the palaces were erected, and that something may have happened to prevent them from being placed on the sculptures of these two sovereigns.
So far as we can discover, no trace of colour has been found on any of the arched steles or isolated statues left to us by Chaldæa and Assyria. This abstention is to be explained by the nature of the materials at the disposal of the sculptor in Chaldæa, the cradle of his art. These were chiefly igneous rocks, very hard, very close in grain and dark in colour, and susceptible of a very high polish. The existence of such a polish disposes of any idea that the figures to which it was given were ever painted. The pigment would not have stayed long on such a surface, and besides, the reds and blues known to the Ninevite artists would have had a very poor effect on a blue-black ground.
On the other hand, when they set to work to model in clay the Assyrians could give free rein to their love for colour. Most of the statuettes found in the ruins of their palaces had been covered with a single uniform tint, which, thanks to the porous nature of the material, is still in fair preservation. The tint varies between one figure and another, and, as they are mostly figures of gods or demons, the idea has been suggested that their colours are emblematic.[288] Thus the Louvre possesses a statuette from Khorsabad representing a god crowned with a double-horned tiara, and covered all over, flesh and drapery alike, with an azure blue.[289] A demon with the head of a carnivorous animal, from the same place, is painted black, a colour that seems to suggest a malevolent being walking in the night and dwelling in subterranean regions.[290]
The Assyrians also made use of what has been sometimes called natural polychromy, that is to say they introduced different materials into the composition of a single figure, each having a colour of its own and being used to suggest a similar tint in the object represented. Several fragments of this kind may be seen in the cases of the British Museum.[291] We may give as examples some eyes in black marble; the ball itself is ivory while the pupil and iris are of blue paste, a sandy frit in which the colour sank deeply before firing. Beards and hair were also made of this material; they have been found in several instances, without the heads to which they belonged. In the ruins from which he took these objects, Layard saw arms, legs and torsos of wood. They were so completely carbonized by fire that they could not be removed; at the least touch they crumbled into powder.
With wood, with enamel and coloured earths, with stones, both soft and hard, and metals both common, like bronze, and precious, like gold and silver, the sculptor built up statues and statuettes in which the peculiar beauty to be attained by the juxtaposition of such heterogeneous materials, was steadily kept in view. With inferior taste and less feeling for purity of form than the Greeks, this art was identical in principal with the chryselephantine sculpture that created the Olympian Zeus and the Athene of the Parthenon.
The idea that sculpture is the art in which form is treated to the exclusion of colour is quite a modern one.[292] The sculptor of Assyria was as ready to mix colour with his contours as his confrère of Egypt, but he made use of it in more sober and reserved fashion. How are we to explain the difference? It is easier to prove the fact than to give a reason for it. It may be said that the sunlight is less constant and less blinding in Mesopotamia than in the Nile valley, and that the artist was not called upon to struggle with such determination, by the profusion and brightness of his colours, against the devouring illumination that impoverishes outlines and obliterates modelling. We must also bear in mind the habits formed by work in such materials as basalt and diorite, which did not lend themselves kindly to the use of bright colours.
In any case the fact itself seems incontestable. We cannot say of the Ninevite reliefs as we said of those of Thebes, that they resembled a brilliant tapestry stretched over the flat wall-surfaces. If, in most of the buildings, touches of paint freely placed upon the accessories and even upon the figures and faces, lightened and varied the general appearance of the sculptures, still the naked stone was left to show all over the bed and over the greater part of the figures. From this we must not conclude, however, that the Assyrians and Chaldæans did not possess, and possess in a very high degree, the love for bold and brilliant colour-schemes which even now distinguishes their degenerate posterity, the races inhabiting the Euphrates valley and the plateau of Iran. But they gratified their innate and hereditary taste in a different way. It was to their woven stuffs, to their paintings in distemper and their enamelled faïence that the buildings of Mesopotamia owed that gaiety of appearance which has led us to compare them with the mosques of Turkey and Persia.
§ 8.—Gems.
“Every Babylonian had a seal,” says Herodotus;[293] this fact seems to have struck him directly he began to explore the streets and bazaars of the great oriental city. These seals, which appear to have attracted the eye of the historian by the open manner in which they were carried and the continual use made of them in every transaction of life, public or private, are now in our museums. They are to be found in hundreds in all the galleries and private collections of Europe.[294]
When Chaldæan civilization became sufficiently advanced for writing to be in widespread use and for every man to provide himself with his own personal seal, no great search for convenient materials was necessary. The rounded pebbles of the river beds gave all that was wanted. The instinct for personal adornment is one of the earliest felt by mankind, and just as the children of to-day search in the shingle of a beach for stones more attractive than the rest, either by their bright colours, or vivid markings or transparency of paste, so also did the fathers of civilization. And when they had found such stones they drilled holes through them and made them into earrings, necklaces and bracelets. More than one set of pebble ornaments has been preserved for us in the Chaldæan tombs. In many instances forms sketched out by the accidents of nature have been carried to completion by the hand of man (Fig. 129). They were not long contented with thus turning a pebble into a jewel. The fancy took them to engrave designs or figures upon them so as to give a peculiar value to the single stone or to sets strung into a necklace, which thus became a kind of amulet (Fig. 130).
In the first instance this engraving was nothing more than an ornament. But one day it occurred to some possessor of such a stone to take an impression upon plastic clay. Those who saw the image thus obtained were struck by its precision, and were soon led to make use of it for authenticating acts and transactions of every kind. The presence of such an impression upon a document would perpetuate the memory of the man who put it there, and would be equivalent to what we call a sign manual.
But even when it developed into a seal the engraved stone did not lose its talismanic value. In order to preserve its quasi-magic character, nothing more was required than the presence of a god among the figures engraved upon it. By carrying upon his person the image of the deity in which he placed his confidence, the Chaldæan covered himself with his protection as with a shield, and something of the same virtue passed into the impressions which the seal could produce in such infinite numbers.

No subject occurs more often on the cylinders than the celestial gods triumphing over demons. Such an image when impressed upon the soft clay would preserve sealed-up treasures from attempts inspired by the infernal powers, and would interest the gods in the maintenance of any contract to which it might be appended.[295]
To all this we must add that superstitions, of which traces subsist in the East to this day, ascribed magic power to certain stones. Hematite, for instance, as its name suggests, was supposed to stop bleeding, while even the Greeks believed that a carnelian gave courage to any one who wore it on his finger.
When engraving on hard stone was first attempted, it was, then, less for the love of art than for the profit to be won by the magic virtues and mysterious affinities, both of the material itself, and of the image cut in its substance. Then, with the increase of material comfort, and the development of social relations, came the desire of every Chaldæan to possess a seal of his own, a signet that should distinguish him from his contemporaries and be his own peculiar property, the permanent symbol of his own person and will. So far as we can tell, none but the lowest classes were without their seals; these latter when they were parties or witnesses to a contract, were contented with impressing their fingernails on the soft clay. Such marks may be found on more than one terra-cotta document; they answer to the cross with which our own uneducated classes supply the place of a signature.
When the use of the seal became general, efforts were made to add to its convenience. In order to get a good impression it was necessary that the design should be cut on a fairly even and regular surface. The river pebbles were mostly ovoid in form and could easily be made cylindrical by friction, and the latter shape at last became so universal that these little objects are always known as cylinders. These cylinders were long neglected, but within the last few years they have been the subject of some curious researches.[296] They may be studied from two different points of view. We may either give our attention to the inscriptions cut upon them and to their general historical significance, or we may endeavour to learn what they may have to teach as to the religious myths and beliefs of Chaldæa. As for us we are interested in them chiefly as works of art. It will be our duty to give some idea of the artistic value of the figures they bear, and to describe the process by which the engraving was carried out.
The cylinders are, as a rule, from two to three-fifths of an inch in diameter, and from three quarters of an inch to an inch and a half in length. Some are as much as an inch and three quarters, or even two inches long, but they are quite exceptional.[297] The two ends are always quite plain—the engraving is confined to the convex surface. As a rule the latter is parallel to the axis, but in some cases it is hollowed in such a fashion that the diameter of the cylinder is greater at the ends than in the middle (Fig. 131).
Nearly every cylinder is pierced lengthwise, a narrow hole going right through it. Those that have been found without this hole are so very few in number that we may look upon them as unfinished. In some cases the hole has been commenced at both ends, but the drill has stopped short of the centre, which still remains solid.
Fig. 131.—Concave-faced cylinder; from Soldi.
Fig. 132.—Cylinder with modern mount; from Rawlinson.
The cylinders were suspended by these holes, but how? In casting about for an answer to this question, the idea that the Babylonian attached the greatest importance to the clear reproduction, in the clay, of every detail of the design engraved upon his seal, has been taken as a starting point, and a system of mounting invented for him which would leave nothing to be desired in that respect (see Fig. 132). It is a reproduction, in small, of a garden roller; as a restoration, however, it can hardly be justified by the evidence of the monuments. Examine the terra-cotta tablets on which these seals were used, and you will see that their ancient possessors did not, as a rule, attempt to impress the whole of the scenes cut in them upon the soft clay. It is rare to find an impression as sharp and complete as that on the tablet from Kouyundjik, which we borrow from Layard (Fig. 133). In the great majority of cases signatories were content with using only one side of their seals, usually the side on which their names were engraved. Sometimes when they wished to transfer the whole of their cylinder to the clay, they did so by several partial and successive pressures.[298]
The imperfect stamp with which the Chaldæans were satisfied could easily be produced without the help of such a complicated contrivance as that shown in our Fig. 132. Nothing more was necessary than to lay the cylinder upon the soft clay and press it with the thumb and fore-finger. The hole through its centre was used not to receive an armature upon which it might turn, but merely for suspending it to some part of the dress or person. In most cases it must have been hung by a simple cord passed round the neck. Now and then, however, the remains of a metal mount have been found in place, but this is never shaped like that shown above. It is a bronze stem solidly attached to the cylinder, and with a ring at its upper extremity (Fig. 134).[299] Cylinders are also found with a kind of ring at one end cut in the material itself (Fig. 135).
How were these cylinders carried? They must have been attached to the person or dress, both for the sake of the protecting the image with which most of them were engraved, and for convenience and readiness in use as seals. In Chaldæa the fashion seems to have been, at one time, to fasten them to the wrist. In those tombs at Warka and Mugheir that we have described, the cylinders were found on the floors of the tomb-chambers, close to the wrist-bones of the skeletons; and the latter had not been moved since the bodies to which they had belonged were laid in the grave.[300] This fashion was apparently abandoned by the Assyrians, for in those reliefs which reproduce the smallest details of dress and ornament with such elaboration, we can never find any trace of the seal beside the bracelets. It is probable that it was hung round the neck and put inside the dress, in front, for greater security. It never occurs among the emblematic objects of which the necklace that spreads over the chest outside the robe, is made up. To this day traders in the East keep their seals in a little bag which they carry in an inside pocket.

The practical requirements of the Mesopotamians were satisfied with a hasty impression from their seals, but we must be more difficult to please. Before we can study the cylinder with any completeness we must have an impression in which no detail of the intaglio is omitted; such a proof is to be obtained by a complete turn of the cylinder upon some very plastic material, such as modelling-wax, or fine and carefully mixed plaster-of-Paris. The operation requires considerable skill. When it is well performed it results in a minute bas-relief, a flat projection, in reverse, of the whole intaglio. The subject represented and its execution can be much better seen in a proof like this than on the original object, it is therefore by the help of such impressions that cylinders are always studied; we make use of them throughout this work. Our Figs. 136 and 137 give some idea of the change in appearance between a cylinder and its impression.
The cutting on the cylinders, or rather on all the engraved stones of western Asia, is in intaglio. This is the earliest form of engraving upon pietra-dura in every country; the cameo is always a much later production; it is only to be found in the last stage of development, when tools and processes have been carried to perfection. It is much easier to scratch the stone and then to add with the point some definition to the figure thus obtained, than to cut away the greater part of the surface and leave the design in relief. The latter process would have been especially difficult when the inscriptions borne by many of the seals came to be dealt with. What long and painful labour it would have required to thus detach the slender lines of the cuneiform characters from the ground! And why should any attempt of the kind be made? As soon as these engraved stones began to be used as seals, there was every reason why the ancient process should be retained. The designs and characters impressed upon deeds and other writings were clearer and more legible in relief than in intaglio. And it must be remembered that with the exception of some late bricks on which letters are raised by wooden stamps, the wedges were always hollowed out. We find but one period in the history of Chaldæa when, as under the early dynasties of Egypt, her written characters were chiselled in relief. It is, then, apparent that the artists of Chaldæa would have done violence to their own convictions and departed from long established habits, had they deserted intaglio for work in relief. That they did not do so, even when their skill was at its highest point, need cause us no surprise.
The Chaldæans naturally began with the softest materials, such as wood, bone, and the shells picked up on the shores of the Persian Gulf. Fragments of some large pearl oysters and of the Tridacna squamosa, on which flowers, leaves, and horses have been engraved with the point, have been brought from lower Chaldæa to London (see Fig. 138).[301] Limestone, black, white, and veined marble, and the steatite of which most of the cylinders are made, were not much more difficult. These substances may easily be cut with a sharp flint, or with metal tools either pointed or chisel-shaped. With a little more effort and patience still harder materials, such as porphyry and basalt; or the ferruginous marbles—serpentine, syenite, hematite—could be overcome. The oldest cylinders of all, those that are attributed to the first Chaldæan monarchy, are mostly of these stubborn materials; their execution was easy enough to the men who produced the statues of Gudea.[302] All that such men required to pass from the carving of life-size figures to the cutting of gems was good eyesight and smaller tools.
It was only towards the end of this period that more unkindly stones began to be used, such as jasper and the different kinds of agate, onyx, chalcedony, rock-crystal, garnets, &c. The employment of such materials implies that of the characteristic processes of gem-cutting, whose peculiarity consists in the substitution of friction for cutting, in the supercession of a pointed or edged tool by a powder taken from a substance harder, or at least as hard, as the one to be operated upon. “The modern engraver upon precious stones,” says M. Soldi, “sets about his work in this fashion. He begins by building up a wax model of his proposed design upon slate. He then takes the stone to be engraved, and fixes it in the end of a small wooden staff. This done he makes use, for the actual engraving, of a kind of lathe, consisting of a small steel wheel which is set in motion by a large cast-iron flywheel turned by the foot. To the little wheel are attached small tools of soft iron, some ending in a rounded button, others in a cutting edge. The craftsman holds the staff with the stone in his left hand; he brings it into contact with the instrument in the lathe, while, from time to time, he drops a mixture of olive oil and diamond dust upon it with his right hand; with the help of this powder the instrument grinds out all the required hollows one after the other.”[303]

The first engravers who attacked precious stones had no diamond dust. They supplied its place with emery powder, which was to be found in unlimited quantities in the islands of the Archipelago, whence it was imported by the Phœnicians at a very early date. Moreover there was nothing to prevent them crushing the precious stones belonging to the class called corundum, such as sapphires, rubies, amethysts, emeralds, and the oriental topaz. No doubt the lathe or wheel was a comparatively late invention. M. Soldi thinks it hardly came into use in Mesopotamia till about the eighth century B.C. Before that the continuous rotary movement that was so necessary for the satisfactory conduct of the operation was obtained by other means. According to M. Soldi they must have employed for many centuries a hand-drill turned by a bow, like that of a modern centre-bit or wimble.[304]

On examining the oldest Mesopotamian engravings on precious stones a skilled craftsman would see at once that nearly all the work had been done with only two instruments—one for the round hollows and another for the straight lines. In the designs cut with these tools we find curiously complete likenesses of the small lay figures with ball-and-socket joints used by painters. Some idea of the strange results produced by these first attempts at gem-engraving may be formed from our reproductions of two cylinders in the collection at the British Museum. The influence of the process, the tyranny of the implement, if we may use such a phrase, is conspicuous in both. Note, for instance, in the first design, which is, apparently, a scene of sacrifice (Fig. 139), how the head and shoulder of the figure on the left are each indicated by a circular hollow. The same primitive system has been used in the cylinder where the god Anou is separated from another deity by the winged globe (Fig. 140). The design is here more complex. The bodies of the two divinities and the wings of the globe are indicated by numerous vertical and horizontal grooves set close together; but the circular hollows appear not only in the globe and in the piece of furniture that occupies the foreground, but also in the knees, calves, ankles, and other parts of the two figures.
