a village of the Marrucini, forming a station on the Via Claudia Valeria between Corfinium and Teate.
It is repeatedly mentioned in the Itineraries, but the distances are variously given. (Itin. Ant.
pp. 102,310; Tab. Peut.
) The line of the ancient highroad is, however, well ascertained, and the position of Interpromium is fixed by ancient remains, as well as mediaeval records, at a place on the right bank of the Aternus, just below the narrow gorge through which that river flows below Popoli.
The site is now marked only by a tavern called the Osteria di S. Valentino,
from the little town of that name on the hill above; it is distant 12 Roman miles from Corfinium (S. Pellino
), and 13 from Teate (Chieti
), or 21 from Pescara,
at the mouth of the Aternuis. (Holsten. Not. ad Cluv.
p. 143; D'Anville, Analyse de l'Italie,
p. 178; Romanelli, vol. iii. p. 117.)
An inscription also mentions Interpromium under the name of Pagus Interprominus (Orell. Inscr.
144; Romanelli, l. c.
); it is called “Interpromium vicus” in the Itinerary of Antoninus (p. 102), and was evidently a mere village, probably a dependency of Teate.
