[5] These stories caution mortals that any guest should be treated as if potentially a disguised divinity, due to both a deity's capacity to instill punishment or grant reward for their behavior, who highly valued generosity and welcoming attitudes towards strangers.
Deities were looked up to as symbols of virtuosity, and thus they were often depicted as performing theoxenia amongst themselves, reinforcing the established idea of xenia as a fundamental Greek custom.
Herman goes on to analyze instances of xenia in political and social relations:"...No less important an element in forging the alliance was the exchange of highly specialized category of gifts, designated in our sources as xénia (as distinct from xenía, the term of the relationship itself) or dora.
He points to the account of Odysseus giving Iphitos a sword and spear after having been given a formidable bow while saying they were "the first token of loving guest-friendship".
Xenia as a custom appears to have been a critical factor that helped determine layouts of homes and of common areas.
[13] In the classical work De Architectura, the Roman architect Vitruvius comments on how xenia was expressed in ancient Greek home layout and decoration.
In particular, he emphasizes the decorative paintings of food in guest apartments of Greek homes:"...When the Greeks became more luxurious, and their circumstances more opulent, they began to provide dining rooms, chambers, and storerooms of provisions for their guests from abroad, and on the first day they would invite them to dinner, sending them on the next chickens, eggs, vegetables, fruits, and other country produce.
[1] Displays of wealth in decoration and in parting gifts for guests likewise serve as both a status symbol and as a demonstration of xenia.
[13] Architectural theorist Simon Weir explained how Vitruvius refers to xenia at the beginning of Book 6 of De Architectura, in the anecdote of Aristippus shipwrecked and receiving hospitality from the Rhodians.
[15] In particular, Architectural historian, Lisa Landrum has also revealed the presence of Xenia in Greek theatre onstage and offstage.
