Besides these mouldings, which were used but very rarely, we need only mention one more detail of the kind, namely, those vertical and horizontal grooves which occur upon the masonry walls and were derived from the structures in wood. They were chiefly used for the ornamentation of the great surfaces afforded by the brick walls (Fig. 261, Vol. I.), but they are also to be found upon stone buildings. We give, as an example, a fragment found at Alexandria, which is supposed to belong to the lower part of a sarcophagus. A curious variation of the same ornament exists in one of the royal tombs at Thebes (Fig. 140), in which each panel is separated from its neighbours by the figures of headless men with their hands tied behind their backs. They represent, no doubt, prisoners of war who have been beheaded, and the decorator has wished, by the use of a somewhat barbarous though graceful motive, to suggest the exploits of him for whom the sepulchre was destined. [Illustration: FIG. 139.--Fragment of a sarcophagus. _Description_, v. 47.] Not much variety was to be obtained from the use of these grooves, but yet they disguised the nudity of great wall spaces, they prevented monotony from becoming too monotonous, while they afforded linear combinations which had some power to please the eye. The Assyrians made use of hardly any other mode of breaking up the uniformity of their brick walls. [Illustration: FIG. 140.--Fragment of decoration from a royal tomb at Thebes. _Description_, ii. 86.] It has been asserted that the first signs of that egg-moulding which played so great a part in Greek architecture are to be found in Egypt. Nestor L'Hôte thought that he recognised it in the entablature, under the architrave, of some pavilions figured in decorations at Tell-el-Amarna and at Abydos.[134] He was certainly mistaken. The outline of the ornament to which he referred has a distant resemblance to the moulding in question, but the place which it occupies gives it an entirely different character; it seems to be suspended in the air under the entablature. In other painted pavilions the same place is occupied by flowers, bunches of grapes, and fruits resembling dates or acorns, suspended in the same fashion.[135] If such forms must be explained otherwise than by the mere fancy of the ornamentist, we should be inclined to see in them metal weights hung round the edges of the awnings, which supplied the place of a roof in many wooden pavilions.
