HOSPITALITY. – From *hoopes* (whence *hospitium*, *hospitalis*, *hospitalitas*), it is the act of welcoming a stranger into one’s home.
I. HOSPITALITY AMONG NON-CHRISTIAN PEOPLES
Hospitality is a universal practice among primitive peoples, both among individuals and groups, because the stranger, being potentially an enemy (*hoopes* and *hostis* share the same root: Varro, *De lingua lat.*, 4,1; Cicero, *De off.*, I, 12), could bring harmful influences to the place where he was hosted; hence it was advisable to make him a friend and even to assist him in case of need. Therefore, among present-day primitive peoples, after the first encounter with a stranger, negotiations are established with exchanges of gifts, followed by the integration of the guest into the community, with various manifestations of friendship: sacrifices, binding with the same rope, exchange of blood, peace pipe, etc. In Rome, in the rites of the *feciales*, the territory of the stranger is taboo, and therefore they use rites of magical purification (verbena) and particular exorcisms when entering hostile territory (Livy, I, 24; IX, 5). In Greece, hospitality is an obligation sanctioned by Zeus Xenios, protector of strangers. In Homer (*Iliad*, III, 35), the Trojan War is caused by Paris’s violation of hospitality against Menelaus. This viewpoint is confirmed by Aeschylus. Odysseus (*Od.*, VI, 119; IX, 175; XIII, 201), when he lands in foreign territory, asks whether it is inhabited by hospitable people who fear this protector of strangers. In Rome, Jupiter is also the protector of the guest (*Juppiter hospitalis*: Cicero, *Ad Quintum fr.*, 2,11). The passing stranger enjoyed the security guaranteed by the *paterfamilias* who hosted him (*hospitium praetatum*). Among the Romans, a *tessera hospitalis* (generally made of wood; in the army it was oral, almost like a password) or a sign of recognition was used, which guaranteed the safety and indemnity of both host and guest (Plautus, *Poen.*, I, 5, 27: *Deum hospitalem ac tesseram mecum fero*).As civilization developed, the duty of hospitality became a mere form of courtesy; Varro (*De arch.*, VI, 10) suggests building, next to the main dwelling, a smaller one intended for receiving guests.
