 i86 A HISTORY OF ART IN CIIALD/KA AND ASSYRIA. In Persia, the diameter of the eye was always very small compared to that of the dome. If we are justified in our belief that the constructors of the Parthian and Sassanide palaces were no more than the perpetuators of systems invented by the architects of Nineveh and Babylon, the Assyrian domes also may very well have been opened at the summit in this fashion. In the bas-relief reproduced in our Fig. 42, the two small cupolas are surmounted with caps around a circular opening which must have admitted the light. Moreover, the elaborate system of drainage with which the substructure of an Assyrian palace was honeycombed would allow any rain-water to run off as fast as such a hole would admit it. 1 Whatever may be thought of these conjectures, it is certain that the architects of Nineveh while they did not neglect accessory sources of illumination counted chiefly upon the doors to give their buildings a sufficient supply of light and air. As M. Place says, when we examine the plans of Sargon's palace at Khorsabad we are as much astonished at the size of the doorways as at the thickness of the walls. 2 " There is not a single doorway, even of the smallest chambers, even of the simple ante-rooms for the use of servants and guards, that is not at least six feet or more w r icle ; most of them are ten feet, and those decorated with sculptures even wider still." In their present ruinous state, it is more difficult to say for certain what their height may have been, judging, however, from the ruins and from the usual proportions of height and width in the voids of Assyrian buildings, the doors at Khorsabad must have risen to a height of between fifteen and twenty-two feet, " Such measurements are those of exceptionally vast openings, especially when we remember that most of them gave access, not to state apartments, but to rooms used for the most ordinary purposes, store-rooms, ante-rooms, kitchens, serving-rooms of all kinds, and bedrooms. When we find architects who were so reluctant as those of Assyria to cut openings of any kind in their 1 In the cupola of the palace at Sarbistan (Fig. 54), a window may be perceived in the upper part of the vertical wall, between the pendentives of the dome. Such openings may well have been pireced under Assyrian domes. From many of the illustrations we have given, it will be seen that the Ninevite architects had no objection to windows, provided they could be placed in the upper part of the wall. It is of windows like ours, pierced at a foot or two above the ground, that no examples have been found. 2 PL CE, Ninire, vol. i. pp. 312-314.
