DECORATION. 273 This coloured clado is to be found even in places to which it seems quite unsuited. At Khorsabad, for instance, it runs across the foot of those semicircular pilasters we noticed in one of the harem chambers (Fig. 101). These pilasters stand upon a plinth between three and four feet high, so that any contact with the dirt of the floor need not have been feared. The existence of the dado in such a position is to be accounted for by supposing that the decorator considered it as the regular ornament for the bottom of a wall. It is more difficult to under- stand why the alcoves believed by MM. Place and Thomas to have been bedrooms were in each case painted with this same band of black. 1 The most curious example of the employment of unbroken tints to which we can point, is in the case of M. Place's observatory. The stages of that building were each about twenty feet high, and each was painted a colour of its own ; the first was white, the second black, the third red, the fourth white. When the excavations were made, these tints were still easily visible. The building seems originally to have had seven stages, and the three upper ones must certainly have been coloured on the same principle as those below them. In his restoration, Thomas makes the fifth vermilion, the sixth a silver grey, while he gilds the seventh and last. 2 In this choice and arrangement of tints there is nothing arbitrary. It is founded on the description given by Herodotus of Ecbatana, the capital of the Medes, " The Medes built the city now called Agbatana, the walls of which are of great size and strength, rising in circles one within the other. The plan of the place is, that each of the walls should out- top the one beyond it by the battlements. The nature of the ground, which is a gentle hill, favours this arrangement in some degree, but it was mainly effected by art. The number of the circles is seven, the royal palace and the treasuries standing within the last. The circuit of the outer wall is very nearly the same with that of Athens. Of this wall the battlements are white, of the next black, of the third scarlet, of the fourth blue, of the fifth orange ; all these are coloured with paint. The two last have their battlements coated respectively with silver and gold." 3 1 PLACE, Ninire, vol. iii. plate 25. 2 Ibid., vol. i. pp. 141-146 ; vol. ii. pp. 79, So ; vol. iii. plates 36 and 37. 3 HERODOTUS (Rawlinson's translation), i. 98.
