We can identify several pairs of doubles or doppelgangers in Edgar Allan Poe's The Narrative of Arthur Gordon Pym. Let's look at some of them.

The frame story to the tale contains the first set of doubles, the narrator, Arthur Gordon Pym, and the author himself. Notice first the similarities in their names, Edgar Allan Poe and Arthur Gordon Pym. Poe supposedly publishes Pym's tale for him as a work of fiction because Pym fears that his fantastic experiences will not be believed otherwise. So Poe actually creates a story within a story with himself as a character.

Within the tale itself, we see Pym and Augustus as doubles, both young boys out for adventure. They find it indeed, but it is hardly what they expect. After the crew mutinies and sets Captain Barnard and some of his crew adrift in a lifeboat, the boys must fend for themselves. However, one of the mutineers, Dirk Peters, turns against his companions and helps Pym and Augustus. The three manage to take the ship back together with another sailor named Parker.

Parker and Augustus become doubles of sorts in their fates. They both die, Augustus from a wound and Parker as the victim of cannibalism. This leaves Pym and Peters as the new doubles and the only survivors. They are picked up by the Jane Guy but left on their own again after Captain Guy and his crew are killed by natives. We might point to Captain Guy and Captain Barnard as doubles in their miserable fates as well.
