VIA POSTUMIA was, as we learn from an inscription (Orell. Inscr. 3121), the proper name of the road that crossed the Apennines direct from Dertona to Genua. But it appears to have fallen into disuse; at least we do not find it mentioned by any ancient writer, and the road itself is included by the Itineraries under the general name of the Via Aurelia. It has therefore been considered more convenient to describe it in that article.
