This main theme is represented by the Greek myth of the Minotaur in the Labyrinth. It shows Carrie’s target who is an ex-Marine and possibly a terrorist standing inside the maze along with her, but elusive to her.
(In classical mythology, the Minotaur was a cursed offspring, with the body of a man and the head of a bull, who grew to be out of control as an adult. The beast was trapped and kept in a maze it could not find its way out of.)
The show is filled with drama and suspense! You can read more HERE.... but ***spoiler alert!!!!*** Keep in mind, as the symbolism of the Homeland maze is discussed in this link, some aspects of the show's storyline are revealed at the same time.
