Throughout the novel, the four friends are haunted by their past as four young and courageous men. The past in The Man in the Iron Mask is thus held dear as it embodies the age of romantic chivalry – an age which is clearly slipping away.
Aramis draws on his shared past with his friends in order to manipulate them.
Raoul lives in and dwells on the past even more so than his surrogate fathers, the four best friends.
