The problem of the names of the Roman forts at the west end of Hadrian's Wall and along the Cumbrian Coast has been eased somewhat by Mark Hassall's inspired elucidation of that sector per lineam valli which lies between Carvoran and Stanwix: he argues that Birdoswald was Banna, and Castlesteads Camboglanna.

2 The meanings Banna = peak or promontory and Camboglanna = curving bank or crooked glen suit Birdoswald and Castlesteads respectively very well indeed.

6 Vindolanda and Magnis are also omitted. All three had appeared previously (10711-12): this is presumably because all three are detached from the Wall, not on it.

13 There is no problem with the substitution of Petriana for Uxellodunum. For a similar case of a unit giving its name to the place where it was stationed, cf. Not. Dig. Oc. XXXV, 24, tribunus cohortis novae Batavorum, Batavis (modern Passau, in Raetia). Such a name could even survive the departure of the unit. Thus the ala I Commagenorum was stationed at modern Tulln (just west of Vienna) which became known as Commagena (Alföldy, G., Noricum (1974), 257).Google Scholar The name survived a change of garrison: Not. Dig. Oc. XXXIV, 36 reads Equites promoti, Comagenis (equites promoti derive from the legions). We may note also that coh. I Hispanorum could have been transferred to the new fort at Burrow Walls when Netherby was given up: the garrison of Netherby in the third century was coh. I Aelia Hispanorum (RIB 968, 976 and 978).
