Great white apes of Mars
A Princess of MarsThe Great white apes of Mars are immense predatory creatures whose place in Martian life is defined by both their threat to children and their role in a decisive encounter with John Carter. Carter first learns of them as a leading cause of childhood death; later, an attack brings him face to face with their strength and establishes the reciprocal loyalty between him and Woola.
Place in Martian Life
Carter’s account places the apes within a society where violent death is common. He estimates that only about one Martian in a thousand dies of illness, while many others die in duels, hunting, aviation, and war. Childhood is another perilous period: great numbers of young Martians fall victim to the Great white apes of Mars. The creatures therefore represent a persistent natural danger in a world already shaped by warfare and hazardous custom.
The apes’ predation is part of the larger contrast between Martian longevity and Martian mortality. Carter says that the average Martian who survives to maturity might live about three hundred years, and that the figure would approach a thousand were it not for the many causes of violent death. The danger posed by the apes belongs to this wider pattern, rather than standing apart as an isolated curiosity.
Encounter in the Ruined City
Carter encounters the creatures after leaving the city with Woola. As he attempts to get away from the animal, he leaps to a high window, only to be seized from behind and pulled into a room. There he sees a huge, ape-like being pinning him down while another approaches with a stone cudgel. The pair’s attack makes the general danger of the species immediate: Carter is alone, trapped indoors, and apparently about to be killed.
The creatures are described as standing roughly ten to fifteen feet tall and having an additional pair of limbs positioned between their upper and lower ones. Their eyes are close together and do not protrude; their ears are high and set farther to the sides than those of the Martians, and their snouts and teeth resemble those of an African gorilla. Carter finds them less repellent in appearance than the green Martians, but their physical scale and strength make them formidable opponents.
Woola’s Intervention and Carter’s Choice
As the second ape prepares to strike, Woola bursts into the room and attacks the creature holding Carter. The first ape escapes through the window, while Woola and the remaining attacker struggle. Carter watches the contest, recognizing that Woola has gained an initial advantage but is in danger of losing. The rescue is not an effortless display of the companion animal’s strength: Woola is vulnerable, and his intervention leaves him needing Carter’s help.
Carter considers fleeing, but sees Woola lying weakened and looking toward him. Remembering that Woola had just risked himself to protect him, Carter turns to face the approaching ape. He throws the cudgel to disrupt its charge, then strikes it with his fists and uses the moment when it falls to seize the weapon and finish the fight. His decision changes the encounter from a rescue by Woola alone into a reciprocal act of protection. Tars Tarkas, Sola, and several warriors arrive as Carter completes the defense, witnessing the conduct that earns their applause.
Narrative Significance
The Great white apes of Mars serve two connected functions in the story: they are a species-level danger in Carter’s account of Martian mortality, and they provide the threat around which his bond with Woola becomes visible through action. The scene contrasts the apes’ formidable size with the choices of the two characters they endanger. Woola protects Carter despite the risk, and Carter abandons the safer option of escape rather than leave his rescuer behind.
The encounter also gives Carter’s relationship with Martian animals a concrete consequence. His growing attachment to Woola is not merely a response to a useful guard; it is tested when Woola is in peril. In that reversal, the apes are more than adversaries: their attack exposes the mutual dependence and loyalty that shape Carter’s survival among the green Martians.
