The third and final theme ofthe Odysseyxeniaxenos phobos
that I’ll discuss here is the code of hospitality (): the requirement to grant shelter, food, and wine, free of molestation, to a visiting stranger– a code sacred to Zeus himself. (By the way, the word, xenophobia, “fear of foreigners,” derives from the Greek (“guest/foreigner”) and (“fear”).
As I’ve discussed above, the historical period during which this poem evolved was very insecure, and so it’s hardly surprising that the Greeks would attach particular significance to this cultural code; imagine the importance of this kind of guarantee for nomadic, sea-faring traders. For the Greeks this code was enforced not only by cultural standards but also by religious values: it was both a right and a rite. (You’ll notice in the Od. that the manner in which hosts honor the code is very ritualistic; when the guests arrive, it’s almost as if the hosts are going through a series of tacitly understood but precisely enforced measures: first give food and shelter but don’t ask any questions until your guest is fed, sheltered, and rested, etc.).
Crucially, xenia operates as a touchstone that exposes virtue or vice and the degree of civilization in almost all the characters in the story.
For example, what started the Trojan War?: a violation of xenia (Paris, to say the least, didn’t behave as a good guest should when he abducted his host’s wife!).
Who are the “good guys” in the story? All those who practice xenia!
What about the suitors?: hey, they’re violating xenia too, and in Odysseus’ own home!: that’s why they deserve to die!
Look at the difference between the Phaiakians, the consummate form of civilization, and the Cyclopes, the most savage form, in this regard. Notice that Polyphemus asks Odysseus for his identity right away, and … well, you know the rest!). I’ll stop typing now because once you get going on this theme, you’re going to find it everywhere.
Here’s my question: where else, and in what sense, is the theme of hospitality brought to the reader’s attention? Your answer can focus on the literal, the interpretative, or both.
