Query: allegorical adventure

Part way through the book I looked up "narthex." It's an antechamber of a church in which penitents wait. That, plus the opening with the heart beating strongly, the quest for an "Eden," the silver "chalice," which the narrator finds in Asiz's frozen hands, the strange story of the rope eater, the birth canal experience in which the narrator slithers through the glacier, looking for a way out to paradise only to return to hell make me think there's more to this story than I have quite figured out to my satisfaction. That's one of the reasons I like it so much. The details ring true without self-conscious display of scholarship. The narrator remains enigmatic, and I am hoping someone has some insights into allegorical interpretations.
