It is possible that the palace had some direct outlet to the open country, so that its inhabitants could escape, unknown to the population of the city, in time of tumult, or could make a nocturnal sortie upon an enemy encamped beneath the mound. If there were any such arrangement it must have consisted of staircases contrived in the mound itself and closed, perhaps, at their inferior extremities with heavy bronze doors. No traces of such passages have been found. But even on the side towards the city, the side on which lay the natural approach to the palace, there is no sign of any ramp or staircase by which the forty-six feet of difference between the levels of the platform and the soil upon which the city was built, could be overcome. The palace had two great monumental façades, each pierced with three large openings flanked by winged bulls. One of these façades (that in front of the hall lettered I on the plan) formed one side of a spacious rectangular court (H) and faced towards the north-east. Some of the buildings surrounding this court have entirely disappeared (see plan), but it is certain that it communicated with the platform of the city walls and that of the palace itself by one opening or more. On the north-eastern side Thomas has placed a wide and easy inclined-plane by which horses and other beasts of burden could mount to the platform, so that the king’s chariot could deposit him at the very door of his apartments, and the heavily laden mules and bullocks could deliver their loads in the store rooms which occupied the whole eastern angle of the mound.[17] The other façade occupies the middle of the south-eastern face and is turned towards the town. It forms a majestic propylæum (Fig. 5) through which the largest of the courts is reached (A on the plan). In the more stately of the city gates foot prints may be traced, while in those that are less ornamental there are marks of wheels, suggesting that some entrances were reserved for pedestrians and others for carriages. It is likely enough that a similar arrangement obtained in the palace, and that in front of this south-eastern gateway there was a flight of steps instead of a continuous ramp. We find such an arrangement at Persepolis where both steps and balustrade, being cut in the rock, are still in good preservation; at Khorsabad, however, there is now no vestige of such a staircase. If the steps have not been carried away they must lie entombed at the very bottom of the _débris_. We cannot say then that our restoration is, in this particular, beyond contention, but it is both probable in itself and entirely in the spirit of Assyrian architecture. These steps must have been the shortest way from the town to the palace. Horsemen, chariots, convoys of provisions had to make a détour and reach both the palace platform and that of the city walls by the south-eastern ramp.
