The unit list comprises three alae and twelve cohorts, all previously known, which accounts for about onethird of the number of auxiliary units attested in Britain during the reign of Hadrian. 13 alae were named on the constitution of 17 July 122; a fourteenth on that of 16 September 124. By 127 two alae had been transferred to Lower Germany. By then, or a little later, ala I Pannoniorum Tampiana had moved to Noricum. There was thus a maximum of ten alae in Britain in the latter part of Hadrian’s reign.
This diploma is now the earliest definite attestation of the full name of the ala Augusta Gallorum Proculeiana in a unit list. It can also be equated with the ala Augusta and ala Augusta ob virtutem appellata on inscriptions and on writing tablets. At the time of issue of this constition
the ala was most likely at Chesters on Hadrian’s Wall where it is named as ala Augusta ob virtutem
appellata on a Hadrianic altar to Disciplina.
The constitution of 17 July 122 names 37 cohorts and a further four are listed on other constitutions
from the reign of Hadrian.While just under a third are named on this diploma it is worth noting that many
are listed in the same relative position as they were in 122 and 127 with cohors I Augusta Nerviana Germanorum milliaria in first place. cohors I Hamiorum sagittariorum is also recorded in Hadrian’s reign in 122, 124, 127, and 135. More specifically it is attested at Carvoran on an altar set up for the welfare of L. Aelius Caesar by T. Flavius Secundus, praef(ectus) coh(ortis) I Hamiorum sagittar(iorum).33 At the same time, 136/138, T. Flavius Secundus is recorded on building stones from the rampart of the fort. He was perhaps the immediate successor of M. Mussius Concessus as prefect.
