We learn further from our authorities, that towards the end of the fourth century the inhabitants of Caledonia were known to the Romans under the names of Dicaledones and Vecturiones, it being conjectured that these correspond to the Caledonians and Mæats of Dio, and the Northern and Southern Picts of a later period. The connection of the latter part of the word Di-caledones with _Caledonii_ is evident, although the significance of the first syllable is doubtful,--some authorities conjecturing that it is the Gaelic word _du_, meaning “genuine.” It appears at all events to be established that during the early history of the Highlands, whatever other divisions may have existed among the inhabitants, those dwelling to the north and those dwelling to the south of the Grampians were two separate confederacies, and were known by distinct names.
Another not unimportant fact to be learned from the Roman historians in relation to the Picts or Caledonians is, that about the middle of the 4th century they were assisted by the Attacots, Saxons, and Scots. As to who the Attacots were it is now impossible to conjecture with anything like certainty, there being no sufficient reason for believing that they were allied to the Irish Scots. It is well enough known who the Saxons were, but how they came at this early period to be acting in concert with the Picts it is difficult to say. It is possible that numbers of them may have effected a settlement, even at this early period, in North Britain, although it is more likely that they were roving adventurers, who had left their homes, from choice or on compulsion, to try their fortune in Britain. They were probably the first droppings of the abundant shower that overwhelmed South Britain a century later. The Romans at this period had an officer with the title of “Comes litoris Saxonici per Britanniam;” and Claudian, in his praises of Stilicho, introduces Britain, saying--
“Illius effectum curis, ne bella timerem Scotica, ne Pictum tremerem, ne littore toto Prospicerem dubiis venturum Saxona ventis.”
It is interesting to notice that this[36] is the first mention made of the Scots in connection with what is now Scotland; but whether there were settlements of them at this time among the Picts, or whether they had come over from Ireland for the purpose of assisting the latter to harass the Romans, it is difficult to say. Probably, as was the case with the Saxons, these were the harbingers of the great migration that reached its culmination about a century and a half later. They appear, from what Ammianus says, to have been at this time a set of destructive vagabonds. We shall have more to say about them further on.
