10. Our imagination longs to reconstruct those gigantic piles as they must have struck the beholder in their towering hugeness, approached from the plain probably by several stairways and by at least one ascent of a slope gentle enough to offer a convenient access to horses and chariots. What an imposing object must have been, for instance, the palace of Sennacherib, on the edge of its battlemented platform (mound of Koyunjik), rising directly above the waters of the Tigris,--named in the ancient language "the Arrow" from the swiftness of its current--into the golden and crimson glory of an Eastern sunset! Although the sameness and unwieldy nature of the material used must have put architectural beauty of outline out of the question, the general effect must have been one of massive grandeur and majesty, aided as it was by the elaborate ornamentation lavished on every portion of the building. Unfortunately the work of reconstruction is left almost entirely to imagination, which derives but little help from the shapeless heaps into which time has converted those ancient, mighty halls. [Illustration: 16.--WARRIORS SWIMMING ON INFLATED SKINS. (Babelon.)] 11. Fergusson, an English explorer and scholar whose works on subjects connected with art and especially architecture hold a high place, has attempted to restore the palace of Sennacherib such as he imagines it to have been, from the hints furnished by the excavations. He has produced a striking and most effective picture, of which, however, an entire half is simply guesswork. The whole nether part--the stone-cased, battlemented platform wall, the broad stairs, the esplanade handsomely paved with patterned slabs, and the lower part of the palace with its casing of sculptured slabs and portals guarded by winged bulls--is strictly according to the positive facts supplied by the excavations. For the rest, there is no authority whatever. We do not even positively know whether there was any second story to Assyrian palaces at all. At all events, no traces of inside staircases have been found, and the upper part of the walls of even the ground-floor has regularly been either demolished or destroyed by fire. As to columns, it is impossible to ascertain how far they may have been used and in what way. Such as were used could have been, as a rule, only of wood--trunks of great trees hewn and smoothed--and consequently every vestige of them has disappeared, though some round column bases in stone have been found.[M] The same remarks apply to the restoration of an Assyrian palace court, also after Fergusson, while that of a palace hall, after Layard, is not open to the same reproach and gives simply the result of actual discoveries. Without, therefore, stopping long to consider conjectures more or less unsupported, let us rather try to reproduce in our minds a clear perception of what the audience hall of an Assyrian king looked like from what we may term positive knowledge. We shall find that our
