The conquests under Vespasian carry us further still into Scotland, and to the Grampians, against the _Caledonians_ under Galgacus. The extent to which they differed from the Britons is not to be collected from the account of Tacitus. We expect that they will be as brave; but ruder. Still, the details which we get from the life of Agricola are few. They fought from chariots, and their swords were broad and blunt. As the swords of the Bronze period were thin and pointed, this is an argument in favour of iron having become the usual material for warlike weapons as far north as the Grampians. The historical testimony to the inferior civilization of the North Britons, or Caledonians, is to be found in a later writer, Dio Cassius, in his history of the campaigns of Severus. "Amongst the Britons the two greatest tribes are the Caledonians and the Mæatæ; for even the names of the others, as may be said, have merged in these. The Mæatæ dwell close to the wall which divides the island into two parts; the Caledonians beyond them. Each of these people inhabit mountains wild and waterless, and plains desert and marshy, having neither walls nor cities, nor tilth, but living by pasturage, by the chase, and on certain berries; for of their fish, though abundant and inexhaustible, they never taste. They live in tents, naked and barefooted, having wives in common, and rearing the whole of their progeny. Their state is chiefly democratical, and they are above all things delighted by pillage; they fight from chariots, having small swift horses; they fight also on foot, are very fleet when running, and most resolute when compelled to stand; their arms consist of a shield and a short spear, having a brazen knob at the extremity of a shaft, that when shaken it may terrify the enemy by its noise; they use daggers also; and are capable of enduring hunger, thirst, and hardships of every description; for when plunged in the marshes they abide there many days, with their heads only out of water; and in the woods they subsist on bark and roots; they prepare, for all emergencies, a certain kind of food, of which, if they eat only so much as the size of a bean, they neither hunger nor thirst. Such, then, is the Island Britannia, and such the inhabitants of that part of it which is hostile to us."
