The ape-man was chained next to the only other white in the dungeon, and he could not help but notice the keen interest that this prisoner took in him from the moment that he entered until the soldiers withdrew, taking the torch with them, leaving the dungeon in darkness. As had been his custom while he was in the home of Maximus Praeclarus, Tarzan had worn only his loin-cloth and leopard-skin, with a toga and sandals out of courtesy for Festivitas when he appeared in her presence. This evening, when he started out with Mpingu, he had worn the toga as a disguise, but in the scuffle that preceded his capture it had been torn from him, with the result that his appearance was sufficient to arouse the curiosity of his fellow prisoners, and as soon as the guards were out of hearing the man spoke to him. "Can it be," he asked, "that you are the white barbarian whose fame has penetrated even to the gloom and silence of the dungeon?" "I am Tarzan of the Apes," replied the ape-man. "And you carried Sublatus out of his palace above your head and mocked at his soldiers!" exclaimed the other. "By the ashes of my imperial father, Sublatus will see that you die the death." Tarzan made no reply. "They say you run through the trees like a monkey," said the other. "How then did you permit yourself to be recaptured?" "It was done by treachery," replied Tarzan, "and the quickness with which they locked the shackles upon me. Without these," and he shook the manacles upon his wrists, "they could not hold me. But who are you and what did you do to get yourself in the dungeons of Caesar?" "I am in the dungeon of no Caesar," replied the other. "This creature who sits upon the throne of Castra Sanguinarius is no Caesar." "Who then is Caesar?" inquired Tarzan. "Only the Emperors of the East are entitled to be called Caesar," replied the other. "I take it that you are not of Castra Sanguinarius then," suggested the ape-man. "No," replied the other, "I am from Castrum Mare." "And why are you a prisoner?" asked Tarzan. "Because I am from Castrum Mare," replied the other. "Is that a crime in Castra Sanguinarius?" asked the ape-man. "We are always enemies," replied the other. "We trade occasionally under a flag of truce, for we have things that they want and they have things that we must have, but there is much raiding and often there are wars, and then whichever side is victorious takes the things by force that otherwise they would be compelled to pay for." "In this small valley what is there that one of you may have that the other one has not already?" asked the ape-man.
