In the year 79, Agricola, a still greater general, extended the influence of Rome to the Firths of Forth and Clyde, which he formed into a frontier, by connecting them with a chain of forts. It was his policy, after he had subdued part of the country, to render it permanently attached to Rome, by introducing the pleasures and luxuries of the Capital. He was the first to sail round the island. In the year 84, having gone beyond the Forth, he was opposed by a great concourse of the rude inhabitants of the north, under a chief name Galgacus, whom he completely overthrew at _Mons Grampius_, or the Grampian Mountain; a spot about which there are many disputes, but which was probably at Ardoch in Perthshire, where there are still magnificent remains of a Roman camp. Tacitus, a writer related to Agricola, gives a very impressive account of this great conflict, and exhibits the bravery of the native forces as very remarkable; but the correctness of his details cannot be much relied on. It appears that Agricola, while on the western coast of Scotland, was desirous of making the conquest of Ireland, which he thought would be useful, both as a medium of communication with Spain, and as a position whence he could overawe Britain. He formed an acquaintance with an Irish chief, who, having been driven from his country by civil commotions, was ready to join in invading it. By him Agricola was informed that the island might be conquered by one legion and a few auxiliaries. The inhabitants, according to Tacitus, bore a close resemblance to the Britons.
