Phorenice, it seemed, had more rage against the Priests’ Clan on the Mountain and more bright genius to help her to a vengeance than I had credited. Her troops stormed easily the gates we had left to them, and swarmed up till they stood where the pathway was broken down. In the fierceness of their rush, the foremost were thrust over the brink by those pressing up behind, before the advance could be halted, and these went screaming to a horrid death in the great gulf below. But it was no position here that a lavish spending of men could take, and presently all were drawn off, save for some half-score who stood as outpost sentries, and dodged out of arrow-shot behind angles of the rock. It seems, too, that the Empress herself reconnoitered the place, using due caution and quickness, and so got for herself a full plan of its requirements without being obliged to trust the measuring of another eye. With extraordinary nimbleness she must have planned an engine such as was necessary to suit her purposes, and given orders for its making; for even with the vast force and resources at her disposal, the speed with which it was built was prodigious. There was very little noise made to tell of what was afoot. All the woodwork and metalwork was cut, and tongued, and forged, and fitted first by skilled craftsmen below, in the plain at the foot of the cleft; and when each ponderous balk and each crosspiece, and each plank was dragged up the steep pass through the conquered gates, it was ready instantly for fitting into its appointed place in the completed machine. The cleft was straight where they set about their building, and there was no curve or spur of the cliff to hide their handiwork from those of the Priests who watched from the ramparts above our one remaining gate. But Phorenice had a coyness lest her engine should be seen before it was completed, and so to screen it she had a vast fire built at the uppermost point where the causeway was broken off, and fed diligently with wet sedge and green wood, so that a great smoke poured out, rising like a curtain that shut out all view. And so though the Priests on the rampart above the gate picked off now and again some of those who tended the fire, they could do the besiegers no further injury, and remained up to the last quite in ignorance of their tactics. The passage up the cleft was in shadow during the night hours, for, though all the crest of the Sacred Mountain was always lit brightly by the eternal fires which made its defence on the farther side, their glow threw no gleam down that flank where the cliff ran sheer to the plains beneath. And so it was under cover of the darkness that Phorenice brought up her engine into position for attack.
