"Dog of a Christian!" murmured Lucius, scrambling to his feet. "How did you know?"

Alyrus caught the words.

"How did I know? When a creature such as thou singest thy wicked songs in broad daylight, he must expect to be heard. A little more and thou, too, wilt go to feed the lions and offer entertainment to the thousands who are weary of other amusements and seek something new. Turn pale, scarecrow, and tremble. Thy day will come, the day when those and others—shall suffer. Ha! ha! it strikes home, doesn't it? Thou fearest, eh? So much the better."

Lucius stood before him, a pitiable figure. His body, brown as an Indian's, was bare almost to the waist. He wore only one garment, a sort of a shirt, made from the skin of one of his own sheep. His legs and feet were as brown as the rest of his body, and as tough as those of an animal.

His hair was black and long, a lock hung over his forehead and hid his black eyes. A long beard fell from cheeks and chin on to his hairy breast. There was nothing attractive about his appearance, it was thoroughly animal.

"I am not afraid," he replied, with such dignity that Alyrus stared at him. "When my time comes, I can die, trusting to a God whom thou knowest not, Alyrus, the Moor, doorkeeper in the house of Aurelius Lucanus."

"Thou knowest me, then?"

"I know thee well." His manner became cringing and servile. "I did but wait here a moment to rest, and fell asleep. I will go on my way."

Alyrus nodded and walked on, going first to the shoemaker's, a tiny shop where a man worked all day and slept at night. Having accomplished this business, and saved himself from having left a lying message for the lawyer, the porter went on his way to the Forum, where all was still now, for the business of the day was over. A few men were passing, but they paid no attention to the Moor.

It was quite dark, heavy clouds from the west were encircling rapidly toward Rome and the wind had increased to a gale. There were sharp flashes of copper-blue lightning and a roar of thunder like booming cannon, echoing against the Alban and Salbine Hills encircling the city.
