## Plot

Erich von Harben, a young German specialized in archaeology and dead languages, with a passion for mountain climbing starts investigating the legend of The Lost Tribe of the Wiramwazi Mountains and disappears. His father meets and asks Tarzan for help.
Tarzan in his search for Erich von Harben finds a lost remnant of the Roman Empire hidden in the mountains of Africa. They are inhabitants of two rival cities Castra Sanguinarius, ruled by Sublatus Imperator, and Castrum Mare, ruled by Validus Augustus.
Erich von Harben and his only remaining safari guide, Gabula, were captured and brought to Castrum Mare, where they meets Mallius Lepus, who takes Erich to his uncle, Septimus Favonius, introducing him as a barbarian from Germany. Erich von Harben falls in love with Favonia, the daughter of Septimus Favonius and makes an enemy of Fulvus Fupus.
Tarzan reaches Castra Sanguinarius, the city being ruled by Sublatus Imperator. Trying to get information about von Harben, Tarzan makes an enemy of the Emperor and his son Fastus. Protecting Dilecta, the daughter of Dion Splendidus, from Fastus he makes a friend out of Maximus Praeclarus, the young patrician officer who brought him to Castra Sanguinarius. Maximus hides him in his house.
Betrayed by a servant, Tarzan and Maximus Praeclarus are captured and chained in the dungeons beneath the Colosseum of Castra Sanguinarius. Here he meets Cassius Hasta, the nephew of Validus Augustus. They fight as gladiators against man and beast and win in the end. Still the emperor does not grant them their freedom. With help of Appius Applosus, a friend of Maximus they escape and lead a revolution against Sublatus with help of the slaves from the nearby villages and the Waziri, brought by Nkima. Once Sublatus is defeated, Tarzan installs Dion Splendidus as Emperor and leaves for Castrum Mare to find Erich and support Cassius Hasta in ascending to the Throne.
In the meantime Erich von Harben and Mallius Lepus were taken prisoners due to the intrigues of Fulvus Fupus, with no idea of Gabula's whereabouts. They were brought to the arena as participants to the games. Just before the games start, Gabula suddenly appears and slays Sublatus in his imperial loge, and in the confusion Erich and Mallius escape and take refuge in a deserted house near the Colosseum. Favonia, abducted by few thieves is brought by chance to the same location where Erich and Mallius free her.
Cassius Hasta returns to Castrum Mare together with Tarzan and the Waziri and encounters no resistance, since without Sublatus, Cassius is the rightful ruler. Tarzan finishes this quest by meeting Erich von Harben.
This novel is notable for the introduction of Nkima, who serves as Tarzan's monkey companion in it and a number of later Tarzan stories. It also reintroduces Muviro, first seen in Tarzan and the Golden Lion, as sub-chief of Tarzan's Waziri warriors.
