Tarzan and the Ant-Men

Tarzan, the king of the jungle, enters an isolated country called Minuni, inhabited by a people four times smaller than himself, the Minunians, who live in magnificent city-states which frequently wage war against each other.

Tarzan befriends the king, Adendrohahkis, and the prince, Komodoflorensal, of one such city-state, called Trohanadalmakus, and joins them in war against the onslaught of the army of Veltopismakus, their warlike neighbours.

He is captured on the battle-ground and taken prisoner by the Veltopismakusians, whose scientist Zoanthrohago conducts an experiment reducing him to the size of a Minunian, and the ape-man is imprisoned and enslaved among other Trohanadalmakusian prisoners of war. He meets, though, Komodoflorensal in the dungeons of Veltopismakus, and together they are able to make a daring escape.

Spanish actor/Tarzan lookalike Esteban Miranda, who had been imprisoned in the village of Obebe, the cannibal, at the end of the previous novel, Tarzan and the Golden Lion, also appears in this adventure.
