[112] WILKINSON thought there was always a layer of stucco, even upon the beautiful granite of the obelisks (_Manners and Customs of the Ancient Egyptians_, 2nd ed., 1878, vol. ii. p. 286.) His statement must be treated with great respect. During his long sojourn in Egypt he examined the remains of the ancient civilisation with great care and patience, but yet we think his opinion upon this point must be accepted with some reserve. There are in the Louvre certain sarcophagi and other objects in hard stone, upon which traces of colour are clearly visible on the sunk beds of the figures and hieroglyphics, while not the slightest vestige of anything of the kind is to be found upon the smooth surface around those carvings. But it is certain that granite was often stuccoed over. MARIETTE has verified that it was so on the obelisk of Hatasu at Thebes; both from the inscription and the appearance of the monument itself he came to the conclusion that it had been gilded from top to bottom, and that the gold had been laid upon a coat of white stucco. "The plain surface," he says, "alone received this costly decoration. It had been left slightly rough, but the hieroglyphs, which had their beds most carefully polished, preserved the colour and surface of the granite." (_Itinéraire_, p. 178.) As for buildings of limestone or sandstone, like the temples of Thebes, they are always coated. When Egyptian buildings were new and their colour fresh, this method of decoration must have given them a most fascinating brilliancy. Whether the pencil alone were employed to trace the designs upon the smooth walls, or whether its powers were supplemented by the work of the chisel, these figures, which succeeded each other in thousands upon every wall and pillar, mingled with inscriptions which were in themselves pictures, and dressed in the most vivid colours, must have at once amused the eye and stirred the brain by the variety of their tints and of the scenes which they represented. But in spite of its breadth and vivacity the system had two grave defects.
