The fort's name is unknown. It could have been Tamium as appears in the Ravenna Cosmography, although this may have been a river name and thus refers to the River Taff. Alternatively it may be Bovium (corrected from Bomio) of the Antonine Itinerary.
The Ravenna Cosmography was compiled by an anonymous cleric in Ravenna around AD 700. It consists of a list of place names covering the world.
