The Marrucini were an Italic tribe that occupied a small strip of territory around the ancient Teate (modern Chieti), on the east coast of Abruzzo, Italy, limited by the Aterno and Foro Rivers.
Other Marrucinian centers included Ceio (San Valentino in Abruzzo Citeriore), Iterpromium (whose ruins are under the Abbey of San Clemente at Casauria), Civitas Danzica (Rapino), and the port of Aternum (Pescara), shared with the Vestini.
[2][3] The opening of the Aes Rapinum reads Aisos pacris toutai maroucai lixs asignas ferenter auiatas toutai maroucai ioues patres ocres tarin cris iouais .
The name of the city or tribe that it gives is touta marouca, and it mentions also a citadel with the epithet tarin cris.
Several of its linguistic features, both in vocabulary and in syntax, are of considerable interest to the student of Latin or Italic grammar (e.g. the use of the subjunctive, without any conjunction, to express purpose, a clause prescribing a sacrifice to Ceres being followed immediately by pacrsi eituam amatens).
