The “Friend and Helper” is Pan, a Greek demigod who’s half human and half goat. Pan oversees nature, among other things. Encountering him on this island, with Portly sleeping between his hooves, suggests that nature can be a protective force. For those who obey “the summons,” respect nature, and look at it with awe, the novel suggests that nature will give back and be helpful. But personifying nature like this also speaks to how powerful nature is. Pan doesn’t
have to protect Portly—his protection isn’t guaranteed.
