‘GUIDE OF SOULS’ is the usual translation given to the Hermes epithet ‘Psychopompos’ and it refers to his role as the god who leads souls into the underworld when they die.
Kerényi establishes the classical etymology of the Soul Guide as Hermes Psychopompos, then complicates it: the guide does not simply escort but ‘leads on’ through trickery, dislodging the soul from any fixed position.
