Written by The Odyssey continually harks back to one phrase that nearly all characters utter at one point or another: “Zeus’s Law.” It sounds like a scriptural concept that was lifted straight from the source poem by director Christopher Nolan. And in spirit, it is. The Odyssey, featuring Matt Damon as Odysseus, is Nolan’s adaptation of the epic.
Zeus’s Law is the mechanism on which the entire plot of this movie runs. It is the reason the Trojan War spirals the way it does and the reason Odysseus can’t get home. And it is also the reason his homecoming plays out the way it does. The movie is different from its source material in many ways. But it does share thematic similarities. Understanding what Nolan means by Zeus’s Law is important, for it is the difference between watching The Odyssey as a war epic and watching it as a three-thousand-year-old morality tale.

1. What Is Zeus’s Law in Greek Mythology?

What The Odyssey calls ‘Zeus’s Law’ is Nolan’s dramatization of xenia. Xenia is the ancient Greek code of hospitality, and it literally means “guest-friendship” (via Britannica.com). Xenia itself is one of the most heavily documented themes underpinning The Odyssey, the actual epic poem. It appears across many hospitality scenes. One instance in Homer’s epic is Telemachus welcoming the disguised Athena in Book One. But the specific phrase “Zeus’s Law” is not a named term on the page. However, it is a pretty compelling interpretation by Nolan. The director himself defines it basically as the Hellenic version of the Golden Rule: “Treat others the way you want to be treated” (via The New York Times).
The rationale behind the code rests on the duality of Zeus as the god of hospitality and the king of the gods. The host was supposed to honor and provide for the guest irrespective of his or her status because the beggar knocking at the door could well turn out to be one of the gods in disguise. It also entailed obligations from the other side, namely providing food, shelter, good treatment of the guest, and limitations regarding the time period of the stay and behavior towards the host.
Breaking the code was read as an insult to the gods themselves, punishable by retribution in the way of the theological concept of Karma in eastern religions such as Buddhism and Hinduism. This is precisely the mechanism Nolan leans on across the film’s almost three-hour runtime.
2. How the Divine Rule Tests Odysseus

Now that the law is set up, Nolan applies it in a stress test on almost all relationships in The Odyssey, on either side of the Aegean. In Ithaca, Penelope (Anne Hathaway) and Telemachus (Tom Holland) are constantly subjected to the pressure of maintaining social obligations of Zeus’s Law. Certain suitors try to manipulate the custom by provoking and insulting their hosts, particularly Telemachus. The reasoning is that if Telemachus retaliates, they can later cite a breach of the law as justification for killing him and taking Penelope as wife without consequence. So, here, the rule that’s supposed to protect the household becomes the very loophole the suitors exploit against it.
Odysseus is indicted by the same law long before he ever reaches home. He and his men break the ancient covenant of Zeus’s law in a major way with the Trojan Horse, a perversion of xenia that destroys the city, Athena’s temple, and every resident of Troy. That single violation sets the terms for everything that follows. Odysseus, his men, and even Agamemnon (Benny Safdie) are punished as they try to make their way home (the king of Mycenae is murdered by his wife, Clytemnestra (Lupita Nyong’o).
It is heavily implied (towards The Odyssey‘s ending by the man himself) that Odysseus’ journey takes a decade because of self-punishment for the atrocities committed by the Greeks on the citizens of Troy. The destruction born from breaking the law gives rise to a fear of strangers that is the exact opposite of what the law was designed to prevent.
Nolan stages that fear in miniature well before Odysseus reaches Ithaca. A village by the sea that Odysseus’ men stop at for food has already begun burning its own homes, in anticipation and fear of the people arriving on their shore. This is a community response so far removed from Xenia’s founding purpose that it plays as the law’s exact negative image. There is the same encroaching sense, familiar from No Country for Old Men (brought on by one of Javier Bardem’s most terrifying villains, Anton Chigurh), of a moral order that can no longer keep pace with the violence arriving at its door.
3. How Zeus’s Law Brings Odysseus’ Tale Full Circle

In the end, the law has become the conscience of Odysseus himself. By casting his guilt about the Trojan Horse as a reflection of Oppenheimer — the scientist who fell apart after creating a destructive force capable of taking down not just a city, but the whole civilization — Nolan makes the guilt his protagonist feels very specific and real. Odysseus even theorizes to Penelope that he and his men, in breaking Zeus’s law, effectively became the “Sea People,” the legendary raiders blamed for unraveling the Bronze Age world, though not mentioned in the source material.
Nolan has borrowed this mystery from history because there was actually a time in history that historians, including archaeologist Eric H. Cline, have attributed the decline of the Bronze Age civilization to the mysterious Sea People in addition to drought, disruptions in trading, earthquakes, and rebellions within the civilization itself (via Time).
In the case of the homecoming, the resolution comes about on account of the very law which damns Odysseus to begin with. In the case of Penelope welcoming her husband, who has been dressed up as a beggar, it is because of that unconditional hospitality that the king of Ithaca is able to get into his own house once again. But Odysseus breaks the law one final time. He has to, for the sake of his son. After he strings the bow and shoots an arrow through the axe-heads, he slaughters the suitors inside his own home. It is a nice payoff, and it is also why, despite this being one of Nolan’s longest movies, The Odyssey never seems boring.
It is this final breach of Zeus’s law that convinces Odysseus to go into exile with his wife and let their son rule Ithaca instead. The law he shattered to win the war is the one he shatters again to win his home back, so his son won’t have to. In the movie, breaking Zeus’s law is treated as something that could end civilization itself, since a world without basic kindness could just as easily collapse under its own weight. A lesson for us 21st-century people here?
