"By the river, near the Mulvian bridge."

At length a pile of low square buildings was barely visible in the haze. It was close to the Tiber, and the rush of the water against the piling of the bridge was distinctly audible. As the two drew near to a closed gateway, a number of mongrel dogs began to snap and bark around them. From within the building came the roar of coarse hilarity and coarser jests. As Pratinas approached the solidly barred doorway, a grating was pushed aside and a rude voice demanded:—

"Your business? What are you doing here?"

"Is Dumnorix sober?" replied Pratinas, nothing daunted. "If so, tell him to come and speak with me. I have something for his advantage."

Either Pratinas was well known at the gladiators' school, or something in his speech procured favour. There was a rattling of chains and bolts, and the door swung open. A man of unusual height and ponderous proportions appeared in the opening. That was all which could be seen in the semi-darkness.

"You are Pratinas?" he asked, speaking Latin with a northern accent. The Hellene nodded, and replied softly: "Yes. No noise. Tell Dumnorix to come quietly."

The two stepped in on to the flags of a courtyard, and the doorkeeper, after rebolting, vanished into the building. Ahenobarbus could only see that he was standing in a large stone-paved court, perhaps one hundred and forty feet wide and considerably longer. A colonnade of low whitewashed pillars ran all about: and behind them stretched rows of small rooms and a few larger apartments. There were tyros practising with wooden swords in one of the rooms, whence a light streamed, and a knot of older gladiators was urging them on, mocking, praising, and criticising their efforts. Now and then a burly gladiator would stroll across the court; but the young noble and his escort remained hidden in shadow.

Presently a door opened at the other end of the courtyard, and some one with a lantern began to come toward the entrance. Long before the stranger was near, Ahenobarbus thought he was rising like a giant out of the darkness; and when at last Dumnorix—for it was he—was close at hand, both Roman and Greek seemed veritable dwarfs beside him.

Dumnorix—so far as he could be seen in the lantern light—was a splendid specimen of a northern giant. He was at least six feet five inches in height, and broad proportionately. His fair straight hair tumbled in disorder over his shoulders, and his prodigiously long mustaches seemed, to the awed Ahenobarbus, almost to curl down to his neck. His breath came in hot pants like a winded horse, and when he spoke, it was in short Latin monosyllables, interlarded with outlandish Gallic oaths. He wore cloth trousers with bright stripes of red and orange; a short-sleeved cloak of dark stuff, falling down to the thigh; and over the cloak, covering back and shoulders, another sleeveless mantle, clasped under the chin with a huge golden buckle. At his right thigh hung, from a silver set girdle, by weighty bronze chains, a heavy sabre, of which the steel scabbard banged noisily as its owner advanced.

"Holla! Pratinas," cried the Gaul, as he came close. "By the holy oak! but I'm glad to see you! Come to my room. Have a flagon of our good northern mead."
