6,1:1 Salerno

This proposed emendation restores a part of the line-work showing the coastal route, as proposed by  Talbert 1480 and Miller 353-4.

Salway 90 objects to this, writing:

... there are only a few places where a rubricated route ends on the coastline itself. The only one of these in which there is any real possibility that it is a deliberate attempt to represent a transfer to travel by sea per loca maritima is after 'Censenia' on the route running northwards along the Lucanian coast from Vibo Valentia.... Although the red line ends abruptly at the coastline, the next stage up the coast, Paestum, is labelled with a distance (Pestu(m) xxxui) and the facing stretch of water is correspondingly labelled Sinus Pestanus.There is a similar lacuna on the land route to the other side of Paestum until the next stage, Salernum (Salerno), from which two routes are shown heading inland. Given the topography of this coastline, alternately rugged and marshy, it is  not implausible that the route advised taking to 'tramping' vessels for this stretch. Nevertheless we should always bear in mind the simple explanation that the copyist has failed to drawn in the red line for the route, as has happened frequently elsewhere.
