PLV Inscriptions (Stanwix)


The fort of the largest unit on Hadrian’s Wall, the double-strength cavalry unit of ala Petriana, is poorly understood and has not produced the volume of inscriptions of some smaller forts elsewhere. Paradoxically, none of the inscriptions actually mentions the unit, although a cavalryman is depicted on one of the tombstones.

The building inscriptions imply the construction in stone of the (originally turf-and-timber) fort by the Twentieth Legion (2028) and its refurbishment by the Sixth (2027) in AD 238–44, but this may be an over-simplistic interpretation. It is certainly salutary that no inscription names the unit in garrison, ala Petriana (which is named in the Notitia Dignitatum). The cavalry tombstone (2030), of the traditional ‘rider’ type showing a barbarian foe being trampled, leaves little room for doubt about a mounted presence here.
