Itineraries

Our site of the Vicus ad Martis Tudertium shows up not only in some inscriptions (see this earlier post), but also in a few ancient and medieval itineraries, which are basically a kind of simple map for trips. Instead of representing the world in a more or less accurate two-dimensional image, itineraries are lists of places along a given route with the distance between each place given in Roman miles. (Of course you can combine these with what look to us more or less like maps, and then you get something like the Peutinger Tablet.)
Thanks to the internet tubes, several of these itineraries are available on-line:

• The Itinerarium Gaditanum ("Cadiz Itinerary") - in which "Martis" or "ad Martis" can be found near the end of the list, 16 (or 17 in one case) miles from Mevania (modern Bevagna) and 17 (or 13 or 18) miles from Narnia (yes, Narnia).
  
• The Tabula Peutingeriana ("Peutinger Tablet") - which is a distorted 2-D map with a number of itineraries put on it in a kind of semblance of geographical reality. (You can search for other versions too.) To find "ad Martis", scroll all the way to the right in the image I've linked to. You'll see Roma there, as a seated figure in a biggish circle. Can't miss it. Above Roma's head is a largish, red letter "A" and a bit above that an "M." Go left from the "M," to "U" then "N" then "E" then "C" (keep going and you'll get "Picenum" backwards). Under the "C" is one bit of writing. Ignore it. Under that, you'll see "vii ad Martis xvi." Careful observers will note that the next stop on this itinerary is neither Mevania nor Narnia.
  
• It's also in the Antonine Itinerary, but I can't find an on-line version of that.
  
• The stupid Bordeaux Pilgrim skipped us on his way from Rome to Milan, and took the eastern branch of the Flaminia.
