That it was indeed a stronghold was the more apparent to us the nearer that we came to it. The plan of it was that of a great fan, spread open upon the hillside, and extending also across the broad sweep of level land between the base of the promontory and the lake. The promontory had been so cut and shaped that its gentle slope had been transformed into six broad semicircular terraces, above the highest of which was a semicircular plateau of very considerable size, on which stood the Treasure-house, that also was the great temple. Along the face of each terrace, and around the face also of the plateau, a heavy defensive wall rose to a height of twenty feet or more; and from the base of the crowning plateau, thence accessible by a single broad flight of stairs—being led through openings in the rampart walls of the terraces, and down each terrace face by means of stair-ways—twelve streets descended, of which the central six ended at the water-side and the remainder against the great outer wall. It was this outer line of strong defence that gave the city—which otherwise would have corresponded curiously closely with the fortified city of Quetzaltepec, described by the Mexican chronicler Tezozomoc—its most distinctive characteristic. Such a vastly thick wall, for the great length of it, as this was I never have seen in any other place; and so solid was the building of it that it would have been proof against any ordinary train of siege artillery. For defence against a foe whose only missile weapons would be javelins and slings and bows, this great wall made the city absolutely impregnable. And that the protection that it gave might be still more complete—and also, as Tizoc explained to us, that in the case of siege the water supply might be assured, together with a supply of fish for food—the wall was carried out into the lake so far as to enclose a basin of more than four acres in extent; within which, should an enemy gain access to the valley, all the boats upon the lake could be brought together and held in safety. And finally, the one entrance to the city was by way of a tunnel-like canal cut in the wall thus rising from the water; the outer end of which canal was closed in ordinary times by a heavy grating, while in war time the inner end also could be closed by means of great metal bars.
It was towards this entrance that the barge that carried us was heading. Presently we reached it, and the grating was raised for our admission by means of chains which were operated from the top of the wall. So low and so narrow was the passage that our heads were within a few inches of the huge slabs of stone of which its roof was formed; and the rowers had need to unstep the mast and then to lay their oars inboard, while they brought the barge through by pushing with their hands against the roof and sides. The canal was fully forty feet long, and thus the enormous thickness of the wall was made apparent to us. It truly was, as I observed to Rayburn, a work that well might be attributed to the Cyclops.
"I never met a live Cyclop, Professor," Rayburn answered, "and I don't believe that these fellows ever did either; but it bothers me to know how they managed to do work like this without a steam-derrick. If we get out of here with whole skins and our hair on our heads, I hope it won't be until I've had a chance to talk to some of their engineers, and so get down to the facts."
A moment later we emerged from the tunnel through the wall, and so entered the enclosed basin that extended along the whole of the city's front. Within the basin were lying many canoes, and also boats of a larger sort that carried oars and that were rigged with a sort of lug-sail; but these all kept away from us, even as all the boats which we had seen during our passage of the lake had given us a wide berth. That our barge—one of those employed exclusively in the Priest Captain's service—was thus shunned was due, as I found later, to the wholesome dread in which the special servitors of the temple and of its head universally were held; for these very frequently abused the authority acquired through their semi-sacerdotal functions by using it as a cloak to cover acts of purely personal oppression, while at all times they were feared as the executors of their master's wrath. There was, indeed (though I did not mention this fact to Fray Antonio), a curiously close resemblance between the officials of this class and the familiars of the Inquisition, both in the duties which they performed and in the fear and hatred which they everywhere inspired.
But even dread of entanglement with the Priest Captain's servants could not restrain the curiosity of the crowd that pressed towards us on the broad pier upon which we disembarked. It was evident that this crowd was not made up of the common folk of the city, and also that it was moved by a purpose far higher than that of a mere idle longing to see something that was strange. From their dress, and still more from the beauty of their ornaments and the elegance of the arms which many of them carried, it was obvious that for the most part these men were citizens of the highest rank; and this fact was still further attested by the dignity of their demeanor and by the reverent age to which the majority of them had attained. So far from manifesting any vulgar excitement, the crowd maintained an absolute silence; and with this an exterior air of calm that was the more impressive because the eager, almost awe-struck expression upon every face showed how strong was the emotion that thus strongly was restrained. But when El Sabio, after much coaxing, crossed the gang-plank between the boat and the pier, and so came to where he could be seen of all plainly, there was a curious low sound in the air as though all at once every man in the crowd had heaved a sigh; and the sound swelled into a loud murmur as Pablo, in obedience to a quick order that I gave him in Spanish, briskly mounted upon the ass's back. In this murmur only one word was intelligible, and that I caught again and again: the prophecy!
But Pablo was no more than fairly seated upon El Sabio's back than the officer in command of our guard took him roughly by the shoulders and snatched him thence to the ground again; which act led Tizoc and me to a quick exchange of startled glances, for it showed very plainly that the Priest Captain—to whom the messenger telling of our coming into the valley had been sent before any of these people had seen Pablo mounted upon El Sabio's back—had anticipated this sign of the fulfilment of the prophecy and had given orders to prevent it. Luckily, the celerity with which Pablo had executed my quick order to mount had saved the day for us; and even more than saved it, for as we passed through the crowd, on our way from the water-side into the city, I caught here and there fragments of comment upon what had just passed which showed that not only was the sign told of in the prophecy recognized, but that the effort on the part of the officer to neutralize it was understood.
But before our going into the city there was a stirring conflict of authority concerning us between the temporal and the spiritual powers. We were no more than fairly landed, indeed, when an officer addressed the barge-master, who continued in charge of our party, and gave him a formal order to bring the strangers directly before the Council of the Twenty Lords. And to this the barge-master replied that he already was under orders to bring the prisoners, immediately upon their landing, before the Priest Captain—and there was something both curious and ominous, it struck me, in the marked manner in which the term "strangers" was employed by one of these men and the term "prisoners" by the other.
At this juncture we had further proof of the foresight of the Priest Captain, and of the determined stand that he was prepared to make rather than to suffer the miscarriage of big plans. While the barge-master and the messenger from the Council still were engaged in hot talk as to which of the two conflicting orders should be recognised, there was the sound of tramping feet and of arms clanking; and then a body of fully one hundred soldiers came quickly from behind a house that was near by the water-side and swept down on a double-quick to where we were standing at the end of the pier. The crowd, jostled aside to make way for the passage of the soldiers, evidently regarded them with astonishment; and this astonishment rapidly changed to anger as the purpose that brought them thither was made plain. In a moment they had closed in around us, separating us from the Council's messenger and from Tizoc; the barge-master placed himself at the head of them, and in sharp, quick tones gave the order to march; and the whole force, with ourselves in the centre of it, went off the pier at a round pace, and thence along a street that led towards the city's heart. Evidently acting under orders, the men broke their platoons and closed in around us; and I was well convinced that this unsoldierly marching was adopted to the end that El Sabio might not be seen.
Fray Antonio agreed with me that the Priest Captain was carrying matters with a dangerously high hand in thus opposing the will of the Council with armed force. This act of his, if Tizoc had correctly represented to us the excited condition of popular feeling, was quite sufficient in itself to stir into violent activity the slumbering fires of mutiny. But whether the revolt that we now believed must surely come would come in time to be of service to ourselves, we could not but look upon as a very open question.
"If this old scoundrel is as sharp as he seems to be," Rayburn said, "and if he keeps things up in the way he's begun, it's about all day with us. His play should be to get rid of us as quick as he can manage it; and I should judge, from the cards that he's put down, that that's precisely the way he means to manage the game. It's not much comfort to us to know that after he's cleaned us out somebody else will rake his pile."
