Road station
Biturs
Biturs is a station whose site is unknown, on the map's road from Nisibis towards Thelser. At the matching point in its sequence the Ravenna list names a Praetoris instead, and one older suggestion even placed the station at Birs Nimrud. From Concon the map counts twenty Roman miles, but the next stage, on to Thelser, runs to a full seventy-five.
