God of Boundaries
Hermes guards every boundary between spaces, whether physical borders between lands or metaphysical ones between worlds.
The Meaning of God of Boundaries
The herma — a squared stone pillar with a head of Hermes on top — stood at every boundary in the Greek world: property lines, city gates, crossroads, and the borders between territories. Moving or defacing a herm was a serious crime against both the god and the community. In 415 BCE, on the eve of Athens's disastrous expedition to Sicily, someone mutilated the hermai throughout the city in a single night. The Athenians were so horrified that they launched a massive investigation, and the scandal helped destroy the career of Alcibiades. Hermes guarded not only physical boundaries but also the threshold between life and death: as psychopomp, he escorted the newly dead from the world of the living to the banks of the Styx. He moved freely between Olympus, earth, and the underworld — the only god who could cross all three boundaries at will.
