Valentia (Latin for "Land of Valens") was probably one of the Roman provinces of the Diocese of "the Britains" in late Antiquity. Its position, capital, and even existence remain a matter of scholarly debate. It was not mentioned in the Verona List compiled around AD 312 and so was probably formed out of one or more of the other provinces established during the Diocletian Reforms. Some scholars propose Valentia was a new name for the entire diocese, but the List of Offices names it as a consular-rank province along with Maxima Caesariensis and the other equestrian-ranked provinces. Present hypotheses for the placement of Valentia include Wales, with its capital at Deva (Chester); Cumbria south of Hadrian's Wall, with its capital at Luguvalium (Carlisle), Modern scholars dismiss the old idea that it was the lands between the Antonine Wall and Hadrian's Wall, possibly with a capital at Habitancum (Risingham), because of the dearth of Roman finds in that area. Name Its name properly refers the Eastern emperor Valens but some also hold it to have honoured Valentinian. Some researchers such as S. H. Rosenbaum, who place Valentia in far northern Britain also believe the name included wordplay with the Latin ("wall"), cf. the island Munitia (wordplay on munitio) of Aethicus Ister's Cosmography. History Ammianus Marcellinus records that, after dealing with the Pannonian rebel Valentine, Count Theodosius "...turned his attention to make many necessary amendments, feeling wholly free from any danger in such attempts, since it was plain that all his enterprises were attended by a propitious fortune. So he restored cities and fortresses, as we have already mentioned, and established stations and outposts on our frontiers; and he so completely recovered the province which had yielded subjection to the enemy, that through his agency it was again brought under the authority of its legitimate ruler, and from that time forth was called Valentia, by desire of the emperor, as a memorial of his success." This occurred in AD 369. It represented the Roman recovery from the Great Conspiracy, which overran northern and western Britain in 367, alongside Germanic attacks on the Roman shores. Ammianus speaks of the establishment of Valentia as the renaming of a recovered province (or possibly all of the territory in Britain), but the List of Offices names Valentia's governor separately alongside all four of the British provinces known from earlier sources. It is possible a new province
