This paper gathers 22 inscriptions (some of them unpublished) dated to Roman period and read on the walls of 11 hypogea from Minorca (Balearic Islands). Although they share a similar context, their contents are diverse: they contain religious texts (the rare Roman god Summanus, as well as some Christian formulae), an epitaph (to Honorius), three graffiti with Vespasianus and some per¬sonal name (Iasidur, Tasidur, Iucuta, Iaso, Iaguren) suggested to have a North-African origin, more concretely Paleo-Amazigh.
