Salisbury Plain has been suggested as the field.
The historian Victor, writing about 360 A.D., ascribes the recovery of Britain to this officer rather than to the personal efforts of Constantius. The suggestion in the text is an endeavour to reconcile his statement with the earlier panegyrics of Eumenius.
See p. 59. An inscription found near Cirencester proves that place to have been in Britannia Prima. It is figured by Haverfield ('Eng. Hist. Rev.' July 1896), and runs as follows: Septimius renovat Primae Provinciae Rector Signum et erectam prisca religione columnam. This is meant for two hexameter lines, and refers to Julian's revival of Paganism (see p. 233).
