It would seem that some buildings had no outward ornament beyond the brilliant whiteness of this stucco, the effect of which may be seen at the present day in the whitewashed houses of the East. The glare of such a wall was happily contrasted with the soft verdure that sometimes grew about it, and the dark blue of the sky against which its summit was relieved. Such a contrast gives importance and accent to the smallest building, as painters who treat the landscapes of the South thoroughly understand. We have reason to believe, however, that as a rule the white stucco served as a background and support to other colours. No Chaldaean interiors have come down to us, while the exteriors are in such bad preservation that we can hardly form any true judgment of the colours and designs with which they were once adorned. But in the case of Assyria we know pretty well how the decorator understood his business, and it is probable that, like his colleagues, the architect and the sculptor, he was content to perpetuate the traditions of his Chaldaean masters. In certain cases the decorator makes use of wide unbroken tints. This is the simplest way of using colour. In the palace of Sargon, for instance, wherever the sculptured slabs are absent we find a plinth painted black in distemper. These plinths are from two to nearly four feet high, according to the extent of the courts or chambers in which they occur. The object of such a dado is clear; it was to protect the lower part of the wall, if not against deliberate violence, at least against dirt. A white stucco in such a position would soon have been disfigured by spots and various marks which would be invisible on a black background. Moreover, the contrast between the plinth and the white wall above it must have had a certain decorative effect.[342] This coloured dado 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 understand why the alcoves believed by MM. Place and Thomas to have been bedrooms were in each case painted with this same band of black.[343]
