“Marduk blast me,” rang his curse, “if I do not flay Rabit for giving me this beast!” But the horse only plunged more wildly.

One last thunder! Darius saw the saplings bowing, the leaves shook down as a falling cloud; out from betwixt the trees shot a beast the like of which the prince had never beheld before. A bull, but a bull of monster size—his horns the span of a bow, his hide mud-brown; out of his mouth, and with the lolling red tongue, one almost saw the live flames breathing, with more flame in the huge balls of his eyes. To see this took one instant. The auroch crashed on until face to face with the two riders, then halted in his shambling run not twenty paces from them, dropped his horns, and lashed his flanks with his tail. Darius wondered no more that mastiffs did not love to bring him to bay.

The Persian’s arrow lay on the bowstring, but he did not shoot. All the trembling had gone out of him. As if by a new sense, he knew that there was something stirring, creeping, in the thicket behind him. Did his ears fail when they heard a human whisper, low, but distinct—a whisper as of a man urging on his hound—“Now!”

Darius did not turn his head. His horse, subdued by his master touch, stood stock still, while the bull glared at them. But Belshazzar was in deadly straits. Try as he might, his beast would not stand steady, and, with the horse plunging underneath him, what chance to strike the bull with the short sword? The king’s face turned livid as he struggled.

“Shoot!” he cried, between his teeth; “shoot!”

Darius’s hand drew the arrow to its head. The auroch shook his horns, bellowed for the last time, and looked from Darius to Belshazzar, from Belshazzar to Darius. Which should feel his charge? The bull fixed his eyes on the king, gave a snort, a bound.

“Shoot!” cried Belshazzar again. As if in echo came a voice out of the thicket, “Back, Nergal! Woe! The king! Do not leap! Too late! Woe!”

And Darius swung himself in the saddle just in time to see the tawny body of Nergal, the royal lion, launching itself—not on the auroch, but on him. The arrow flew to meet the lion. It was Ahura the Great who shed on Darius the power that sent the startled charger with a wide bound to one side by the mighty press of a knee. The lion leaped. His flying claws tore the leather on the Persian’s sleeve. A mighty snarl—the beast dashed upon the turf. The saving of Ruth had been no shot like this. The deed was done too swiftly for thought or fear, while all around the woods were ringing with a fiercer conflict. The auroch had sought his prey the moment Nergal had leaped on his. The king had striven desperately to master his steed, but vainly. The monster caught the horse under his horns and tossed mount and rider in the air. Halting in full charge, he shook his great head and looked about. The horse was disembowelled—dying. The king, cast upon the greensward, was struggling to rise. He had lost his sword. The auroch lowered his head again. Still a foe? He would trample it out instantly!

“Help, in Marduk’s name, help!” the king was calling.
