CHAPTER XXXIV.

The day following the three ruffians lingered about the site of the old Hippodrome—through the open space of which the citizens passed in going from one part of the city to another. Toward evening a stone was thrown against the bronze-sheathed column, or walled pyramid, which still held some of the great plates that in the palmy days of Byzantium made it one of the wonders of the city. It was the signal for alertness. A short-bodied, long-armed, red-haired man, dressed in the white kilt and gold-embroidered jacket of a citizen, sauntered leisurely through the Hippodrome. He measured with his eye the space which once blazed with the splendor of fashion, when, beneath the imperial eye of a Justinian or Theodosius, the horses of Araby and Thracia ran, and the factions of "the Blues" and "the Greens" shouted, and the whirling wheels of the golden chariots sprinkled the dust upon the multitudes.

The man paused to gaze at the bronze column of three intertwined serpents, with silver-crested heads, which was believed to have been brought from the temple at Delphi to his new city by the great Constantine. He stood reverently before the tall Egyptian obelisk of rose-granite, whose light red glowed with deeper hue in the eastern flush of the twilight sky; puzzled over its vertical lines of hieroglyphs which thirty centuries had not obliterated, and studied the figures on its marble base, representing the machines used by the engineers of Theodosius in hoisting the great monolith to its place, a thousand years ago. Broken statues—the spoil of conquered cities in generations of Greek prowess which shamed the supineness of the present, stood or lay about the grand pillar of porphyry, which was once surmounted by the statue of Apollo wrought by Phidias.

"Shame for such neglect!" muttered the man. "A people that cannot keep its art from cracking to pieces with age, cannot long keep the old empire of the Cæsars."

The narrow street to the north of the Hippodrome square shut out the remnant of daylight as the man turned into it. His attention was drawn by the groaning of some poor outcast crouching in the dark shadow of an angle in the wall. As he stooped to inspect this object a stunning blow fell upon his head. Two stalwart men instantly pinioned his arms. They rolled his helpless body a few yards, and carried or slid it down a flight of steps into a dark cavern, whose sides echoed their footfalls and whispers, as if it were the place of the last Judgment where the secrets of life are all to be proclaimed. Reaching the bottom, one of the men produced a light. The glare seemed to excavate a hollow sphere out of the thick darkness, but revealed nothing, except the spectral flash of the bats flitting around the heads of the intruders, and the damp earthen floor upon which the men had thrown their victim. At length great forms rose through the gloom, like the trunks of a forest. The water of a subterranean lake gleamed from near their feet, but its smooth black sheen was soon lost in the darkness. A small boat, or raft, was near, into which the man was lifted; one of the ruffians sitting on his feet, the other by his head, while the third propelled the craft by pushing against great granite pillars between which they passed. After going some distance the boat ground its bottom against a mass of fallen masonry and dirt, which made a sort of island, perhaps twenty feet across. Here they landed, and dragged their victim.

"What would you have with me?" said the prostrate man.

"It is enough that we have you," said Pedro, in broken Greek. "We want nothing more; not even to keep your miserable carcass, since we have already got our pay for burying it. I'll be your father-confessor and shrive you. If you like the Latin—Absolvo te! and away go your sins as easily as I can strip this gold-laced jacket off your back. Or if you prefer the Greek—By the horns of Nebuchadnezzar, I've forgotten the priestly words! But I'll shrive you all the same without the holy mumble. And if you want to pray a bit yourself, why fold your feet in front of your nose and kneel on your back."

"Why do you kill me?" said the man. "I am nothing to you."

"Nothing to us, but something to him who has hired us. As honest men we must do what we were paid to do."

"Unless I can pay you more," said the man, instantly taking a hopeful hint.

"Do you wear the belt of Phranza, that you think you can pay so much?" replied one of the ruffians, feeling about the person of the helpless man.

"What I have I give—a hundred ducats."

"A hundred! Are you love-crossed that you value life so little? You'll skin well, my gentle lambkin; and as you are half tanned already, we will sell your hide to the buskin maker for almost that sum; and your fat (feeling his ribs) will grease a hundred galley masts. A thousand ducats is your value, you Albanian imp!"

"I do not possess so much," said the victim.

"But your sister does," said the ruffian; and not noting the surprised look of the man, continued: "We have arranged for that. Your life is worth to us just one thousand ducats of gold. Sign this!" producing a bit of paper on which was something written.

"I cannot read it in this light. You read it. I may trust such honest fellows as you are."

The man read—"To my sister, the Albanian, at the house of Phranza. I am in danger from which I can escape only if you will give the bearer one thousand ducats. Speak not to any one of it, or my life is forfeit. That you may know this is genuine the bearer will show you my ring and a clip of my hair."

"Give me your ring; and, comrade, warm the wax to seal the letter," said Giovan.

"But I am not the man you seek," said the victim.

"And who in the devil's name are you then?"

"A mere stranger."

"Prove it!"

"Take the ring, and the lady will not recognize it."

"We shall see," said the ruffian, "but we will take the hundred ducats now to pay for any trouble you have put us to."

His belt was stripped off, and its golden contents ripped out. The victim was untied, first having been completely disarmed. The three men entering the boat, pushed off in the direction from which they had entered.

The island prisoner watched the receding light as it flashed its long rays on the water, illumined the arches of the roof, and lit the crouching figures in the boat. The multiplying pillars became like a solid wall as the light receded, until at length the darkness was complete. The sound of the boat as it scratched against the stone at the landing, gave place to the most oppressive silence.

To attempt escape in the direction of the entrance would be folly. If he could find his way his captors would doubtless be on guard and easily overpower him, as he would have to wade or swim. But to remain where he was would be as hazardous, for the wretches would not risk exposure for the sake of the hundred ducats they had secured; but would probably return and put him out of the way of witnessing against them.

As he meditated, a low rumble like distant thunder, ran along the arches. "Some passing vehicle in the city above," he concluded.

A light drip, as of a bat's wing touching the water! Another! and another! "Strange that they should be so regular!" thought the man. "There must be some inlet: I will explore."

He walked cautiously into the water in the direction of the sound. Soon he was beyond his depth; but, being an expert swimmer, kept on; his outstretched arms answering as antennæ of some huge water-spider, and guarding him from collision with the pillars.

The dripping sound became louder. Now it was just above his head. He felt his way with his hands until it became evident that he was at the end or side of the subterranean lake. But the shore was steep; indeed, a wall. Fixing his fingers into the crevices between the stones, he was able to raise himself half out of the water. Reaching up with one hand he felt the curved edge of a viaduct, by which the dark lake was evidently fed, or had been in earlier days. But, bah! The water now trickling through it was foul. The spring had been stopped, and the viaduct become a sewer; fed doubtless through its rents with the soakage of the city.

But might there not be an opening into the upper air? If not, a great human mole—especially if, to blind scratching power, he adds the skill of one trained in the art of engineering—can possibly make an opening.

The prisoner climbed into the viaduct. It was large enough to allow him to crawl a short distance. A faint glimmer of light proved the correctness of his surmise that it was connected with the surface. But fallen stones blocked his way. As he lay planning with fingers and brain for his further progress, voices sounded from the reservoir. They were those of two of the cut-throats returning. He pushed himself back to the opening. His captors had missed him at the island. If they knew of this sluice, or chanced to come upon it in their search, he was lost in his present position; for a pair of bare heels was the only weapon he could show against their sharp daggers. He let himself down into the water, and swam silently away. The light, however, from his captors' lamp came nearer.

"Hist!" said one. "He is yonder; perhaps by the devil's window."

The boat pushed directly toward the viaduct he had left.

While they explored the opening, which might well be called the window into the blackness of darkness of the nether world, their victim swam rapidly, keeping always in the shadow of the great pillars. But the boat was upon his track again.

The fugitive now made a fortunate discovery. Several feet below the surface of the water the base of each pillar projected far enough for standing room. This base had probably marked the height to which the water was originally allowed to rise. By standing upon one of these projections, he was able to move round the pillar, so as to keep its huge block between himself and his pursuers. Thus they passed him. By the light in the boat he could discern the ground or shore near which was the entrance.

Returning to coast the other side of the cavern, they had passed close by him, when, his foot slipping, he was projected into the water. The wretches hailed with grim joy the splash, and turned the boat in the direction of the noise. But, dropping beneath the surface, the man swam to a pillar near by, from which he watched their baffled circuit of his former retreat.

This chase could not be kept up endlessly. Plunging again under the water, he swam directly to the boat. Rising suddenly, he grasped its side with main weight and overturned it. The cries of the men and the splashing of the boat echoed a hundred times among the arches; while the hissing oil of the open lamp, which, poured on the surface of the water, blazed for a moment, made as near a representation of pandemonium as this world ever affords, except in the brain of the demented.

Though the captive had endeavored to keep his bearings, and had not lost for an instant his presence of mind, the swirling of the boat had destroyed all impression of the direction he should take. He remembered that on one of the pillars the projecting base was broken. It was that on which he had stood when he caught a glimpse of the ground near the entrance. If he could find that pillar again he could take his bearings as readily as if a star guided him. Several pillars were tried before the talismanic one was discovered. Feeling the broken place, and recalling the way in which he stood upon the narrow ledge when he saw the entrance, he took his course accordingly, and swam on.

One of his pursuers had evidently found a lodgment somewhere, and was calling lustily to his comrade for help. But there came back no answer to his call.

On went the swimmer until the light of the outer world gleamed through the crevice of the door, twenty or thirty feet above him, and he crawled upon the ground.

Squeezing the water from his garments, he climbed the stairway, and, opening the heavy and worm-eaten doors, peered out. The street was crowded with passers; for another day had come since his entrance to the old reservoir. In his half naked and bedrabbled condition he hesitated to make his exit, and returned to the bottom of the stairs. A hand on the door above made him leap to one side.

Giovan entered. Peering intensely into the shadows, he descended the steps. Pausing a moment he whistled through his teeth. There was no response. He whistled louder on his fingers. A shout came back.

"Help! Giovan—help!"

Giovan's dagger protruded from his belt. Another's hand suddenly drew it, and, before he had recovered from his surprise, it entered his neck to the haft. The Italian's short breeches, velveteen jacket and skull cap were made to take the place of the remnant of the prisoner's once most reputable wardrobe, and he sallied forth.
