1,5:1 Augustobona

The copyist seems to have created a spur to the line Bibe - Augustobona without the authorization of an itinerary to back it up. Talbert 640 observes: "Conceivably, the continuation from Bibe to the Avg Svessor(vm) - Dvrocortoro route is a copyist's erroneous addition (compare the horizontal continuation from Gerainas in 2B2)." This seems sensible, especially taking account of the necessary modifications (1,4:1) to the linework at left.
