DECORATION. 285 were from two to three inches high. In later days Arab architects followed the example thus set and pressed the elegant forms of the cufic alphabet into their service with the happiest skill. 1 For the composition of one of these figures of men or animals a large number of units was required, and in order that it might preserve its fidelity it was necessary not only that the separate pieces should exactly coincide but that they should be fixed and fitted with extreme nicety. At Babylon they were attached to the wall with bitumen. On the posterior surface of several enamelled bricks in the Louvre a thick coat of this sub- stance may be seen ; it has preserved an impression of all the roughnesses on the surface of the crude mass to which it was applied. It is impossible to decide whether this natural mortar was allowed to fill the joints between one enamelled square and another or not. None of these bricks have been found in place, and none, so far as we know, unbroken. The coat at the back may have rendered the adherence so complete that no further precaution was necessary. In Assyria, so far at least as Khorsabad is concerned, they were content with less trouble. The bricks forming the enamelled archivolt of which we have spoken are attached to the wall with a mortar in which there is but little adhesive power. 2 It offered no resistance when M. Place stripped the archway in order that he might enrich his own country with the spoils of Sargon. But for an accident that sent his boats to the bottom of the Tigris not far from Bassorah this beautiful gateway would have been rebuilt in Paris. 3 To fit all these squares into their proper places was a delicate operation, but it was rendered easy by long practice. Signs, or rather numbers, for the guidance of the workmen, have been noticed upon the uncovered faces of the crude brick walls. 4 Still 1 Two of these enamelled letters are in the Louvre. See also upon this subject, PLACE, Ninive, vol. ii. p. 86. I have also seen some in the collection of M. Piot. 2 PLACE, Ninive, vol. i. p. 236. 3 Only two rafts arrived at Bassorah ; eight left Mossoul, so that only about a fourth of the antiquities collected reached their destination in safety. The cases with the objects despatched by the Babylonian mission, that is by MM. Fresnel, Oppert, and Thomas, were included in the same disaster. But for this the Assyrian collections of the Louvre would be less inferior than they are to those of the British Museum. 4 PLACE, Ninive, o. i. p. 253.
