Final answer:
In 'The Odyssey,' the Cyclops Polyphemus breaks the tenet of xenia, the ancient Greek concept of hospitality, by imprisoning and eating some of Odysseus's men instead of receiving them properly as guests.
Step-by-step explanation:
In Homer's epic poem The Odyssey, the Cyclops Polyphemus breaks the tenet of xenia, which refers to the ancient Greek concept of hospitality. When Odysseus and his men arrive at the cave of Polyphemus seeking shelter and sustenance, they expect to be received with the customary respect and provision that guests are due. Instead, Polyphemus disregards these expectations, showing contempt for the sacred laws of hospitality by imprisoning and eating some of Odysseus's men. This act directly opposes the values celebrated within Homer's epic poems, where adherence to social norms such as hospitality, glory, and excellence is deemed essential. By breaking the code of xenia, Polyphemus triggers the series of events that lead to his own suffering and the escape of Odysseus, highlighting the importance of this code in ancient Greek society.
