The three bodies of infantry were the Victores Juniores Britanniciani, the Primani Juniores, and Secundani Juniores. The six bodies of cavalry, the Equites Catafractarii Juniores, the Equites Scutarii Aureliaci, the Equites Honoriani Seniores, the Equites Stablesiani, the Equites Syri, and the Equites Taifali. The Equites Catafractarii were stationed at Morbium, supposed by Horsley to be Templeburgh on the south bank of the river Don. The provinces are twice given in the Notitia, and the order is the same in both—Maxima Cæsariensis, Valentia, Britannia Prima, Britannia Secunda, Flavia Cæsariensis. The position usually assigned to these provinces rests entirely upon the authority of the spurious Richard of Cirencester, and involves the supposition that when Constantine divided the provinces into four, he substituted the name of Maxima Cæsariensis for that of Lower Britain, and divided Upper Britain into three provinces, forming the district of Wales into a separate province called Britannia Secunda; but if the order in the Notitia is geographical, and proceeds from north to south, Maxima Cæsariensis is the most northerly, then Valentia and Britannia Prima extend across the island from west to east. Then south of them Britannia Secunda, and farther south Flavia Cæsariensis; and thus, before Valentia was formed, Maxima Cæsariensis and Britannia Prima would represent what had been Lower Britain, and the Dux Britanniæ would command the troops within it; Britannia Secunda and Flavia Cæsariensis what had been Upper Britain, and the Comes tractus maritimi, the troops within it. The new province would be formed in the west to meet the invasion in a new quarter from a new people, the Scots; and a new commander, the Comes Britanniarum, or Count of the two Britannias, would be placed there to protect the western frontier.
