"He calls himself Erich von Harben," replied Metellus.

"Erich von Harben," repeated Tarzan. "I know him. Where is he now? Is he safe?"

Caecilius Metellus turned his eyes in the direction of the ape-man. "How do you know Erich von Harben, Sanguinarian?" he demanded. "Perhaps then the story that Fulvus Fupus told Validus Augustus is true—that this Erich von Harben is in reality a spy from Castra Sanguinarius."

"No," said Maximus Praeclarus. "Do not excite yourself. This Erich von Harben has never been in Castra Sanguinarius, and my friend here is not himself a Sanguinarian. He is a white barbarian from the outer world, and if his story be true, and I have no reason to doubt it, he came here in search of this Erich von Harben."

"You may believe this story, Metellus," said Cassius Hasta. "These both are honorable men and since we have been in prison together we have become good friends. What they tell you is the truth."

"Tell me something of von Harben," insisted Tarzan. "Where is he now and is he in danger from the machinations of this Fulvus Fupus?"

"He is in prison with Mallius Lepus in Castrum Mare," replied Metellus, "and if he survives the games, which he will not, Fupus will find some other means to destroy him."

"When are the games held?" asked Tarzan.

"They start upon the ides of August," replied Cassius Hasta.

"And it is now about the nones of August," said Tarzan.
