The child who was destined to play this part in the shaping of a new Europe was born before the close of the fourth century, perhaps in the year 389 A.D. His father, Calpurnius, was a Briton; like all free subjects of the Empire, he was a Roman citizen; and, like his father Potitus before him, he bore a Roman name. He belonged to the middle class of landed proprietors, and was a decurion or member of the municipal council of a Roman town. His home was in a village named Bannaventa, but we cannot with any certainty identify its locality.[21] The only Bannaventa that we know lay near Daventry, but this position does not agree with an ancient indication that the village of Calpurnius was close to the western sea. As the two elements of the name Bannaventa were probably not uncommon in British geographical nomenclature, it is not a rash assumption that there were other small places so called besides the only Bannaventa which happens to appear in Roman geographical sources, and we may be inclined to look for the Bannaventa of Calpurnius in south-western Britain, perhaps in the regions of the lower Severn. The village must have been in the neighbourhood of a town possessing a municipal council of decurions, to which Calpurnius belonged. It would not be right to infer that it was a town with the rank of a _colonia_, like Gloucester, or of a _municipium_, like St. Albans; for smaller Roman towns, such as were technically known as _praefecturae_, _fora_, and _conciliabula_, might be managed by municipal councils.[22]
