Snake

The snake is a symbol of the trouble lying ahead for Glass. Glass has a hallucination of a snake with black eyes biting him and tearing into his wounds. Although the snake is really there, it doesn't attack him.

Anstadt

The Anstadt is the rifle of Hugh Glass, which symbolizes his biggest desire for revenge.

Buffalo

Glass eating the buffalo is a symbol of him building up strength, as buffalos are revered by Native American tribes for their strength and stability. This is seen as a precursor to Glass's physical power and energy in the future.

Pawnee Indians/Superstition

The Pawnee Indians hold firm beliefs in superstitions. Glass begins to act as if he is possessed, which terrifies the superstitious Indians. Instead of killing Glass or keeping him as prisoner, they save his life, not wanting to have any part in harming a "possessed demon."
