Xenia is an ancient Greek concept that emphasizes hospitality and the generous treatment of guests. It is rooted in the belief that showing kindness to strangers is a moral duty, often linked to the favor of the gods. This practice was vital in Greek culture, where travel was common, and safe lodging was essential. In literature, xenia is often illustrated through stories of heroes and their interactions with hosts. For example, in Homer's epic poems, such as the Iliad and the Odyssey, the importance of hospitality is highlighted through various encounters between characters, showcasing the cultural significance of this tradition.
