The "paintings in the temple of Belos," described by Berosus, were in all probability carried out in the same way. They decorated the walls of the great temple of Bel Merodach at Babylon, where "all kinds of marvellous monsters with the greatest variety in their forms" were to be seen.[372]
We see therefore, that both by sacred and profane writers is the important part played by these paintings in the palaces and temples of the capital affirmed. And Ctesias, who is not content with allusions, but enters into minute details, tells us how the work was executed, and how its durability was guaranteed. The modern buildings of Persia give us some idea as to the appearance of those of Babylon. No doubt the plan of a mosque differs entirely from that of a temple of Marduk or Nebo, but the principle of the decoration was the same. If the wand of an enchanter could restore the principal buildings of Babylon we should, perhaps, find more than one to which the following description of the great mosque of Ispahan might be applied with the change of a word here and there: "Every part of the building without exception is covered with enamelled bricks. Their ground is blue, upon which elegant flowers and sentences taken from the Koran are traced in white. The cupola is blue, decorated with shields and arabesques. One can hardly imagine the effect produced by such a building on an European accustomed to the dull uniformity of our colourless buildings; he is filled with an admiring surprise that no words can express."[373]
If we should set about making such a comparison, the principal difference to be noticed would be that arising out of the prohibitions of the Koran. The Persian potter had to content himself with the resources of pure ornament, resources upon which he drew with an exquisite skill that forbids us to regret the absence of men and animals from his work. The coloured surfaces of the Babylonian buildings must have had more variety than those of the great mosque at Ispahan or the green mosque at Broussa. But the same groups and the same personages were constantly repeated in the same attitudes and tints, so that their general character must have been purely decorative. Even when they were combined into something approaching a scene, care was taken to guard, by conventionality of treatment and the frequent repetition of familiar types and groups, against its attracting to itself the attention that properly belonged to the composition of which it formed a part. The artist was chiefly occupied with the general effect. His aim was to give a certain rhythm to a succession of traditional forms whose order and arrangement never greatly varied, to fill the wide surfaces of his architecture with contrasts and harmonies of colour that should delight the eye and prevent its fatigue.
Were the colours as soft and harmonious as we now see them in those buildings of Persia and Asia Minor that will themselves soon be little more than ruins? It is difficult to answer this question from the very small fragments we possess of the coloured decorations of the Babylonian temples and palaces, but the conditions have remained the same; the wants to be satisfied and the processes employed a century ago were identical with those of Babylon and Nineveh; architect and painter were confronted by the same dazzling sun, and, so far as we can tell, taste has not sensibly changed over the whole of the vast extent of country that stretches from the frontiers of Syria to the eastern boundaries of the plateau of Iran. New peoples, new religions, and new territorial divisions have been introduced, but industrial habits have remained; in spite of political revolutions the workman has transmitted the secrets of his trade to his sons and grandsons. Oriental art is now threatened with death at the hands of Western competition. Thanks to its machines Europe floods the most distant markets with productions cheaper than those turned out by the native workman, and the native workman, discouraged and doubtful of himself, turns to the clumsy imitation of the West, and loses his hold of the art he understood so well. Traditions have become greatly weakened during the last half century, but in the few places where they still preserve their old vitality they may surely be taken as representative of the arts and industries of many centuries ago, and as the lineal descendants of those early products of civilization on which we are attempting to cast new light. If, as everything leads us to believe, the colours and patterns worked by the women of Khorassan and Kurdistan on their rugs and carpets are identical with those on the hangings in the palaces of Sargon, of Nebuchadnezzar, and of Darius, why should we not allow that the tints that now delight us on the mosques of Teheran and Ispahan, of Nicæa and Broussa, are identical with those employed by the Chaldæan potter?
There is no doubt that both had a strong predilection for blue—for the marvellous colour that dyed the most beautiful flower of their fields, that glowed on their distant mountains, in their lakes, in the sea, and in the profound azure of an almost cloudless sky. Nature seems to have chosen blue for the background of her changing pictures, and like the artists of modern Persia those of antique Mesopotamia understood the value of the hint thus given. In the fragments of Babylonian tiles brought home by travellers blue is the dominant colour; and blue furnishes the background for those two compositions in enamelled brick that have been found in situ. The blue of Babylon seems however to have had more body and to have been darker in shade than that of the Khorsabad tiles.
We have already referred to this inferiority in the Assyrian enamel. It may be explained by the fact that the Assyrian architect looked to sculpture for his most sumptuous effects; he used polychromatic decoration only for subordinate parts of his work, and he would therefore be contented with less careful execution than that required by his Babylonian rival. The glazed tiles of Assyria were not, as in Chaldæa, quasi bas-reliefs. Their tints were put on flat; the only exception to this being in the case of those rosettes that were made in such extraordinary numbers for use on the upper parts of walls and round doorways; in these the small central boss is modelled in low relief (see [Figs. 121] and [122]).

These glazed bricks were chiefly used by the Assyrian architect upon doorways and in their immediate neighbourhood.[374] M. Place found the decoration of one of the city gates at Khorsabad almost intact.[375] The enamel is laid upon one edge of the bricks, which are on the average three inches and a half thick. Figures are relieved in yellow, and rosettes in white against the blue ground. A band of green marks the lower edge of the tiara.[376] The same motives and the same figures were repeated for the whole length of the band. The figures are winged genii in different postures of worship and sacrifice. They bear in their hands those metal seals and pine cones that we so often encounter in the bas-reliefs. Distributed about the entrance these genii seem to be the protectors of the city, they are beneficent images, their gesture is a prayer, a promise, a benediction. On each side of the arch, at its springing, there is one of greater stature than his companions ([Fig. 123]). His face is turned towards the vaulted passage. Upon the curve of the archivolt smaller figures face one another in couples; each couple is divided from its neighbours by rosettes ([Fig. 124]).
