"And now Cyllenian Hermes began to summon the souls of the Suitors"
Here, Hermes is acting in his role of psychopomp
– the guide of the dead. He collects newly deceased spirits and escorts them to the Underworld, where they are then integrated into the land of the dead. Hermes can be seen on white-ground lekythoi (vases used to pour oil during funeral rites) performing this function.
