"I must have him out of the way," said Cethegus to himself, "when the news arrives.--When you have repulsed the barbarians," he said aloud to Constantinus, "no doubt you will make a sally. What an opportunity to gather laurels while your commander is yet at a distance!"

"Yes," said Constantinus, "they shall see that we can fight, even without Belisarius."

"But you must aim with more composure," said Cethegus, turning to a Persian archer and taking his bow. "Do you see that Goth, the leader on horseback? He shall fall."

Cethegus drew the bow. The Goth fell from his horse, pierced through the neck by the arrow.

"And you use my shooting-machines clumsily too! Do you see that oak-tree? A leader of one of the Gothic thousands is standing beneath it, clad in a coat of mail. Pay attention!"

He directed the machine; aimed and shot. The mailed Goth was pierced through and through, and nailed to the tree.

Just then a Saracen horseman rode quickly up below the wall.

"Archon," he cried to Constantinus, "Bessas begs for reinforcements for the Prænestinian Gate! The Goths are advancing."

Constantinus looked doubtfully at Cethegus.

"Pshaw!" said the latter; "the only attack to be feared will be made upon the Gate of St. Paul, and that is well defended, I am certain. Tell Bessas that he is scared too soon. Besides, I have six lions, ten tigers and twelve bears in the Vivarium waiting for the next feast at the Circus. Let them loose upon the barbarians for the present. It will afford a spectacle for the Romans."
