Many carried torches, and as their light flowed into the depths below a medley of affrighted yells went up. From the darkness huge evil eyes glimmered and titanic shapes loomed vaguely in the gloom. The mob wavered, ready to stampede, but di Strozza strode stolidly downward and the pack called on Allah and followed. Now the light showed a huge cavern in the center of which stood a black and utterly abhorrent altar, hideously stained, and flanked with grinning skulls laid out in strangely systematic lines. The horrific figures were disclosed to be huge images, carved from the solid rock of the cavern walls, strange, bestial, gigantic gods, whose huge eyes of some glassy substance caught the torchlight.
The Celtic blood in Cormac sent a shiver down his spine. Alexander built the foundations of this fortress? Bah—no Grecian ever carved such gods as these. No; an aura of unspeakable antiquity brooded over this grim cavern, as if the forbidden door were a mystic threshold over which the adventurer stepped into an elder world. No wonder mad dreams were here bred in the frenzied brain of Skol Abdhur. These gods were grim vestiges of an older, darker race than Roman or Hellene—a people long faded into the gloom of antiquity. Phrygians—Lydians—Hittites? Or some still more ancient, more abysmal people?
The age of Alexander was as dawn before these ancient figures, yet doubtless he bowed to these gods, as he bowed to many gods before his maddened brain made himself a deity.
At the foot of the stairs lay a crumpled shape—Musa bin Daoud. His face was twisted in horror. A medley of shouts went up: "The djinn have taken the Syrian! Let us begone! This is an evil place!"
"Be silent, you fools!" roared Nadir Tous. "A mortal blade slew Musa —see, he has been slashed through the breast and his bones are broken. See how he lies. Someone slew him and flung him down the stairs—"
The Persian's voice trailed off, as his gaze followed his own pointing fingers. Musa's left arm was outstretched and his fingers had been hacked away.
"He held something in that hand," whispered Nadir Tous. "So hard he gripped it that his slayer was forced to cut off his fingers to obtain it—"
Men thrust torches into niches on the wall and crowded nearer, their superstitious fears forgotten.
"Aye!" exclaimed Cormac, having pieced together some of the bits of the puzzle in his mind. "It was the gem! Musa and Kai Shah and di Strozza killed Skol, and Musa had the gem. There was blood on Abdullah's sword and Kai Shah has a broken arm—shattered by the sweep of the Nubian's great scimitar. Whoever slew Musa has the gem."
Di Strozza screamed like a wounded panther. He shook the wretched slave.
"Dog, have you the gem?"
The slave began a frenzied denial, but his voice broke in a ghastly gurgle as di Strozza, in a very fit of madness, jerked his sword edge across the wretch's throat and flung the blood-spurting body from him. The Venetian whirled on Kai Shah.
"You slew Musa!" he screamed. "He was with you last! You have the gem!"
"You lie!" exclaimed the Turk, his dark face an ashy pallor. "You slew him yourself—"
His words ended in a gasp as di Strozza, foaming at the mouth and all sanity gone from his eyes, ran his sword straight through the Turk's body. Kai Shah swayed like a sapling in the wind; then as di Strozza withdrew the blade, the Seljuk hacked through the Venetian's temple, and as Kai Shah reeled, dying on his feet but clinging to life with the tenacity of the Turk, Nadir Tous leaped like a panther and beneath his flashing scimitar Kai Shah dropped dead across the dead Venetian.
Forgetting all else in his lust for the gem, Nadir Tous bent over his victim, tearing at his garments—bent further as if in a deep salaam and sank down on the dead men, his own skull split to the teeth by Kojar Mirza's stroke. The Kurd bent to search the Turk, but straightened swiftly to meet the attack of Shalmar Khor. In an instant the scene was one of ravening madness, where men hacked and slew and died blindly. The flickering torches lit the scene, and Cormac, backing away toward the stairs, swore amazedly. He had seen men go mad before, but this exceeded anything he had ever witnessed.
Kojar Mirza slew Selim and wounded a Circassian, but Shalmar Khor slashed through his arm-muscles, Justus Zehor ran in and stabbed the Kurd in the ribs, and Kojar Mirza went down, snapping like a dying wolf, to be hacked to pieces.
Justus Zehor and Yussef el Mekru seemed to have taken sides at last; the Georgian had thrown in his lot with Shalmar Khor, while the Arab rallied to him the Kurds and Turks. But besides these loosely knit bands of rivals, various warriors, mainly the Persians of Nadir Tous, raged through the strife, foaming at the mouth and striking all impartially. In an instant a dozen men were down, dying and trampled by the living. Justus Zehor fought with a long knife in each hand and he wrought red havoc before he sank, skull cleft, throat slashed and belly ripped up.
Even while they fought, the warriors had managed to tear to shreds the clothing of Kai Shah and di Strozza. Finding naught there, they howled like wolves and fell to their deadly work with new frenzy. A madness was on them; each time a man fell, others seized him, ripping his garments apart in search for the gem, slashing at each other as they did so.
Cormac saw Jacob trying to steal to the stairs, and even as the Norman decided to withdraw himself, a thought came to the brain of Yussef el Mekru. Arab-like, the Yemenite had fought more coolly than the others, and perhaps he had, even in the frenzy of combat, decided on his own interests. Possibly, seeing that all the leaders were down except Shalmar Khor, he decided it would be best to reunite the band, if possible, and it could be best done by directing their attention against a common foe. Perhaps he honestly thought that since the gem had not been found, Cormac had it. At any rate, the Sheikh suddenly tore away and pointing a lean arm toward the giant figure at the foot of the stairs, screamed: "Allahu akbar! There stands the thief! Slay the Nazarene!"
It was good Moslem psychology. There was an instant of bewildered pause in the battle, then a bloodthirsty howl went up and from a tangled battle of rival factions, the brawl became instantly a charge of a solid compact body that rushed wild-eyed on Cormac howling: "Slay the Caphar!"
Cormac snarled in disgusted irritation. He should have anticipated that. No time to escape now; he braced himself and met the charge. A Kurd, rushing in headlong, was impaled on the Norman's long blade, and a giant Circassian, hurling his full weight on the kite-shaped shield, rebounded as from an iron tower. Cormac thundered his battle cry, "Cloigeand abu," (Gaelic: "The skull to victory.") in a deep-toned roar that drowned the howls of the Moslems; he freed his blade and swung the heavy weapon in a crashing arc. Swords shivered to singing sparks and the warriors gave back. They plunged on again as Yussef el Mekru lashed them with burning words. A big Armenian broke his sword on Cormac's helmet and went down with his skull split. A Turk slashed at the Norman's face and howled as his wrist was caught on the Norse sword, and the hand flew from it.
Cormac's defense was his armor, the unshakable immovability of his stance, and his crashing blows. Head bent, eyes glaring above the rim of his shield, he made scant effort to parry or avoid blows. He took them on his helmet or his shield and struck back with thunderous power. Now Shalmar Khor smote full on his helmet with every ounce of his great rangy body behind the blow, and the scimitar bit through the steel cap, notching on the coif links beneath. It was a blow that might have felled an ox, yet Cormac, though half- stunned, stood like a man of iron and struck back with all the power of arm and shoulders. The Circassian flung up his round buckler but it availed not. Cormac's heavy sword sheared through the buckler, severed the arm that held it and crashed full on the Circassian's helmet, shattering both steel cap and the skull beneath.
