From this we learn that in the 3d century there were two divisions of the inhabitants of the Highlands, known to the Romans as the Caledonians and Mæats or Mæatæ, the latter very probably inhabiting the southern part of that territory, next to the wall of Antonine, and the former the district to the north of this. As to whether these were Latinized forms of native names, or names imposed by the Romans themselves, we have no means of judging. The best writers on this subject think that the Caledonians and Mæats were two divisions of the same people, both living to the north of the Forth and Clyde, although Innes,[28] and one or two minor writers, are of opinion that the Mæats were provincial Britons who inhabited the country between the wall of Hadrian and that of Antonine, known as the province of Valentia. However, with Skene,[29] Mr. Joseph Robertson, and other able authorities, we are inclined to think that the evidence is in favour of their being the inhabitants of the southern portion of Caledonia proper. Herodian,[30] who wrote about A.D. 240, tells us that the Caledonians were in the habit of marking or painting their bodies with figures of animals, and that they wore no clothes in order that these figures might be preserved and exhibited. The next reference made by a Roman writer to the inhabitants of Caledonia we find in a panegyric pronounced in his presence on the Emperor Constantius Chlorus, by Eumenius, a professor of rhetoric at Augustodunum (_Autun_) in Gaul, in the year 296 or 297, who speaks of the Britons, in the time of Cæsar, having been attacked by the half-naked _Picts_ and Irish. To what people the orator meant to apply the term _Picts_, around which there has clustered so much acrimonious disputation, we learn from another oration pronounced by him on the same emperor, before his son Constantine, in the year 309, in which, recording the actions of Constantius, he speaks of the woods and marshes of _the Caledonians and other Picts_. After this no further mention is made of the Caledonians by any Roman writer, but towards the end of the 4th century Ammianus Marcellinus, in his account of the Roman transactions in Britain, speaks of the Picts in conjunction with the Saxons, Scots, and Attacots harassing the provincial Britons about the year 364. Further on he informs us that at this time the Picts were divided into two tribes or nations, the Dicaledones and Vecturiones, remarking, at the same time, that “the Attacots were a warlike race of men, and the Scots a people much given to wandering, and in the habit of ravaging or laying waste the districts into which they came.”[31]
