CERFE´NNIA a town of the Marsi, not mentioned by Pliny or the other geographers, but placed by the Itineraries on the Via Valeria, 13 miles from Alba Fucensis, and 17 from Corfinium. Its site is fixed by Holstenius at the foot of the hill on which stands the modern village of Coll‘ Armeno, where an old church of Sta Felicitàstill bears in ecclesiastical records the adjunct in Cerfenna. It was at the foot of the remarkable pass over the Apennines called in the Tabula the Mons Imeus (now the Forca Caruso), which led from thence to Corfinium. From an inscription published by Holstenius (Orell. Inscr. 711) we learn that this part of the Via Valeria was first constructed, or at least rendered passable for carriages, by the emperor Claudius, who continued it from Cerfennia to the Adriatic at the mouth of the Aternus.
