Hospitality in Greek Society

In Greek culture hospitality is not only important because Zeus is the God of hospitality and will literally kill you if you disappoint him, or sleep with your spouse. Also, because as we know from reading myths in which Zeus disguises himself to look like a swan and mortal man, that disguises are very common with the Gods. Since the Greeks are fully aware of this then they are very cautious and welcoming because they never know if the stranger knocking at their door could be a God in disguise. And for example, Telemachus, of the Odyssey was most definitely making the right move when he was so welcoming to Athena in the disguise of Mentes.
