Longman, Green, Longman, Roberts, & Green (London), 1863. this work was debunked over the course of the mid-19th century. Modern scholars are uncertain whether the province was named for the western senior emperor Valerius Maximian or the eastern junior emperor Galerius Maximian. Birley has argued that Maxima and Flavia originally consisted of a single province, which received the name ''Britannia Caesariensis'' as a mark of favour for support against the rebel Allectus in 296. Although Flavia is usually thought to have been formed from the old province of Lower Britain, Birley proposes that Upper Britain was divided in two (between Prima and Caesariensis) and then three (Prima, Maxima, and Flavia). This repeats Camden's earlier theory (relying on Sextus Rufus) that Maxima was formed first and Flavia followed sometime after. Stillingfleet, Edward
