“Vinicius, art thou not mistaken?” asked Petronius. “Did Lygia really draw a fish for thee?”

“By all the infernal gods, one might go mad!” cried the young man, with excitement. “If she had drawn a bird for me, I should have said a bird.”

“Therefore she is a Christian,” repeated Chilo.

“This signifies,” said Petronius, “that Pomponia and Lygia poison wells, murder children caught on the street, and give themselves up to dissoluteness! Folly! Thou, Vinicius, wert at their house for a time, I was there a little while; but I know Pomponia and Aulus enough, I know even Lygia enough, to say monstrous and foolish! If a fish is the symbol of the Christians, which it is difficult really to deny, and if those women are Christians, then, by Proserpina! evidently Christians are not what we hold them to be.”

“Thou speakest like Socrates, lord,” answered Chilo. “Who has ever examined a Christian? Who has learned their religion? When I was travelling three years ago from Naples hither to Rome (oh, why did I not stay in Naples!), a man joined me, whose name was Glaucus, of whom people said that he was a Christian; but in spite of that I convinced myself that he was a good and virtuous man.”

“Was it not from that virtuous man that thou hast learned now what the fish means?”

“Unfortunately, lord, on the way, at an inn, some one thrust a knife into that honorable old man; and his wife and child were carried away by slave-dealers. I lost in their defence these two fingers; since, as people say, there is no lack among Christians of miracles, I hope that the fingers will grow out on my hand again.”

“How is that? Hast thou become a Christian?”

“Since yesterday, lord, since yesterday! The fish made me a Christian. But see what a power there is in it. For some days I shall be the most zealous of the zealous, so that they may admit me to all their secrets; and when they admit me to their secrets, I shall know where the maiden is hiding. Perhaps then my Christianity will pay me better than my philosophy. I have made a vow also to Mercury, that if he helps me to find the maiden, I will sacrifice to him two heifers of the same size and color and will gild their horns.”

“Then thy Christianity of yesterday and thy philosophy of long standing permit thee to believe in Mercury?”
