Abstract

Hospitality can be considered a key institution in the social relationships in the ancient Mediterranean. To identify the people involved in a hospitality agreement, in certain contexts small objects were used in a similar way to a password, which the Greeks called symbolon and the Romans tessera hospitalis. We know how the latter were used thanks to Plautus' Poenulus. At least 64 pieces are currently known which may be identified as tesserae hospitales. All come from the Western Mediterranean. The majority contain brief inscriptions, written in Etruscan, Latin, Greek, or Celtiberian. They share a series of common features, which impart a clear family resemblance beyond geographic, cultural, or linguistic borders
