“ Palace-Mounds and Palaces.—In order to give a certain dignity to the royal residence, to secure the fresh breezes, and to render them more easily defended, the Assyrians, as well as the Babylonians and the Persians, built their palaces upon lofty artificial terraces, or platforms. These eminences, which appear like natural, flat-topped hills, were constructed with an almost incredible expenditure of human labor. The great palace-mound at Nineveh, called by the natives Koyunjik, covers an area of one hundred acres, and is from seventy to ninety feet high. ”
